Q: Every few hours—sometimes minutes!—my living room and one side of my kitchen lose electrical power. I’ll check the breaker panel and, sure enough, a circuit breaker has tripped…again. Should I call an electrician, or is there a simple DIY fix I can try first?

A: While it’s frustrating when a circuit breaker keeps tripping, they are important safety mechanisms. Designed to shut off the electrical current when something goes wrong, circuit breakers are one of the best ways of protecting a home from an electrical fire. “When a circuit breaker trips, typically it is because we use too much electricity, which causes it to overload and turn off,” says Christopher Haas, expert electrician and owner of Haas & Sons Electric in Millersville, Maryland. For those who need an electrical panels 101 refresher course or aren’t sure how to reset circuit breakers, each breaker has an on/off switch and controls a separate electrical circuit in the home. When a breaker trips, its switch automatically flips “off,” and it must be manually turned back on to restore electricity to the circuit. For those wondering, “Is it dangerous if a circuit breaker keeps tripping?” the answer is that it can be, depending on the source of the problem. An electrician can ultimately deal with the root issue, but a little sleuthing will reveal whether it’s something that’s easily remedied.

In many cases, the cause of a circuit breaking tripping is an overloaded circuit.

A circuit overloads when more electrical current is being drawn through the wires than they can handle, tripping the circuit breaker. If this happens, there may be a few additional signs:

• Buzzing noises coming from outlets
• Devices charging slowly
• Electrical outlets not working
• Flickering lights
• Scorch marks on outlets and light switches

If a circuit breaker keeps tripping in one room, homeowners can test for circuit overload by turning off all the switches in the affected area and unplugging all appliances and devices. After the breaker is flipped back on, the devices can be turned back on one at a time, with homeowners waiting a few minutes in between to see if the circuit remains on. If the breaker trips before all the appliances are turned on, the experiment can be repeated, this time turning them on in a different order. It may be necessary to do this several times to find out how many appliances can be operated at once before the circuit overloads.

“As a short-term solution, you can unplug unnecessary appliances to prevent tripping circuit breakers. You may still get some trips, but you can limit them by unplugging devices that you don’t need to use,” advises Dan Mock, vice president of operations at Mister Sparky , an electrical company with 90 locations in the U.S. The best long-term solution, however, is to pay an electrician for the cost to rewire the house and add additional circuits. The cost to replace an electrical panel is about $1,274 on average.

Other times, the issue may be caused by a short circuit.

A “short” circuit means that two wires that should not be coming into contact are inadvertently touching, triggering a sudden surge of electricity through the wires. A short can occur in an outlet, a switch, or within an appliance if wires are loose or have been chewed through by mice or pets. Some signs of a short circuit include:

• Popping sounds
• Discolored outlets or switches
• Burning smells

Testing to see if an appliance has a short is similar to testing for an overloaded circuit. When an appliance that has a short in its wiring is turned on, it will immediately trip the circuit. Homeowners can also try plugging it into an outlet in a different room. If the breaker for that room trips, there’s a short in the appliance (if it’s unclear what breaker goes to what room, the breaker can be identified with one of the best circuit breaker finders ). Electrical shorts can be a major fire hazard, so it’s a good idea to call a licensed electrician for this circuit breaker repair. It’s wise to stop using the outlet or appliance until a pro takes care of the problem.

Another potential cause of a circuit breaker tripping is a ground fault.

A ground fault occurs when the electricity running through a home’s wiring diverts from the wiring loop and travels to the ground, usually due to faulty wiring or water infiltration in an outlet or switch box. Water is a conductor, which is why walking through puddles is often listed as something not to do in a power outage in case of downed power lines. Once water makes contact with wires, electricity can jump from the wiring loop and follow the water trail. This creates a surge in electricity leading to a tripped circuit breaker. If a person comes in contact with the electricity that is on its way to the ground, this can result in electrocution. Homeowners may notice a few signs of a ground fault, including:

• Tripped GFCI (ground fault circuit interrupter) outlets;
• A burning smell coming from an outlet; and
• Lights flickering.

Newer electrical breakers have features designed to protect against the danger of ground faults. According to Haas, “Ground fault breakers sense electricity going to earth as opposed to going through the wires of the circuit. You’ll find [these] for bathrooms, kitchens, garages, exteriors, and basements.” GFCI outlets are another safety feature that shut off the electric current within a fraction of a second of sensing a ground fault.

If a ground fault is the problem, the cause of the errant water must be discovered and repaired, and any damaged wiring must also be replaced. It’s also a good idea to install GFCI outlets in rooms where water is commonly used. A GFCI outlet costs $210 on average.

Sometimes a bad or worn-out circuit breaker can be the culprit.

In some cases, the circuit breaker itself may be faulty. Breakers that are old, damaged, or were installed incorrectly may trip frequently for no apparent reason. Alternatively, faulty breakers may not trip when they are supposed to, leaving the home at risk of electrical fire. Some signs of a bad circuit breaker include:

• The circuit breaker getting hot and tripping frequently;
• The circuit breaker won’t reset;
• It has been over 10 years since the breaker was last serviced; and
• The breaker has scorch marks.

An important electrical safety tip to keep in mind is that resetting a breaker over and over again can cause what is called an arc flash, which is a small electrical explosion that can be deadly. If resetting the breaker once does not remedy the issue, it’s a good idea for the homeowner to hire an electrician near them who knows how to replace a circuit breaker safely. Mock warns, “Don’t take any chances with circuit breakers. Instead, call a licensed electrician who knows the safe ways to replace breaker boxes, upgrade circuits, and diagnose potential electrical problems in your home.” Wiring a breaker box is a job to leave to an experienced electrician.

A professional electrician can help determine the specific cause of a frequently tripping circuit breaker.

Most circuit breaker problems—aside from those explained in the sections above—will need to be inspected and addressed by a licensed electrician. According to the Electrical Safety Foundation International (ESFI) , each year “thousands of people in the United States are critically injured and electrocuted as a result of electrical fires, accidents, [or] electrocution in their own homes.” While homeowners may be tempted to save on electrician costs by attempting circuit breaker replacement or repair themselves, electrical work is not suitable for casual DIYers. “Yes, you have to pay, but you can save many hours of head-scratching by hiring an electrician. Electricians will also have all the right tools for diagnosing and repairing the circuit,” Haas adds. “Lastly, they will come with a warranty/guarantee should something arise, and they will typically return at no additional cost.”

Electric - breaker trips after 30 minutes

A breaker trips after 30 minutes. All switches and recptacles were replaced in the last 2-4 years. It started about a week ago at 3am. I replaced the breaker but that didn’t resolve the issue. Nothing new has been added to the circuit recently. There are a lot of of two way and thfee way switches on this circuit but nothing new. The only other thing I can think of it there must be a loose wire on one of the switches and I’ve checked about half so far.

does anyone have any other ideas

When a standard breaker trips after a period of time, it usually means that its circuit is slightly overloaded, carrying current somewhat above the breaker's rating.

Is the breaker a GFI or AFCI type?

Cory_cregger original author.

its the $8 replacement from Home Depot - i don’t see it labeled on the breaker. the house was built in 1989 before a lot of the codes changed. the kitchen is not on the circuit and only a bathroom light so I assume GFI. It’s odd that it randomly went out since nothing was added to the circuit.

Any recommendations?

You say it's a replacement, so it's not original, right? When was it replaced? If it's not a GFI or AFI one (does it have any reset buttons on it?) then your cheapest solution is to get a new one and try it out. Do you know how to replace it?

I replaced it - That was the first thing I tried. It’s still tripping around 30 mins

You say "There are a lot of of two way and thfee way switches on this circuit," but also "the kitchen is not on the circuit and only a bathroom light." Which is it?

Does the breaker feel at all warm when it trips? Even slightly?

How does the buss bar the breaker plugs onto look? Any corrosion or discoloration? Do you hear any unusual noises from the panel near that breaker, such as humming or hissing?

How old is your panel? What brand?

See if you can borrow a clamp ammeter to measure the actual current being drawn from the breaker.

If the breaker cost $8, it's not a GFI or AFCI type.

Changing a breaker is usually a waste of time and money. They just don't fail that often, especially non-GFI and non-AFI breakers. I don't recommend replacing one without being certain it was defective. One way to test a breaker is to swap its wire onto the adjacent breaker. If the symptom follows the wire, it's not the breaker.

Sorry, cory, I didn't read your original post carefully enough. Have you discovered all the circuits which are on this breaker? If you turn them all off, does the breaker still trip? If the answers are "yes", then I think you'll have to open the boxes, one at a time, and disconnect the incoming wire and redo the test. As DavidR says, it might be a heavy load; if you can find a clamp-on current meter, then when the boxes are open, measure the current.

Could be a circuit which is near capacity and it trips from the load placed on it when the refrigerator kicks on (which is a momentary large current draw). You could test this by temporarily unplugging the refrigerator and seeing if the breaker still trips.

Circuit Breaker Tripping: Troubleshooting Guide

Hubert Miles | Licensed Home Inspector, CMI, CPI

Updated on January 5, 2024

A circuit breaker tripping results from short circuits, overloaded circuits, and ground faults. In each case, an unintended excessive flow of current triggers the trip. You must reset the circuit breaker by flipping it back on to restore power.

Circuit breakers trip because they cannot handle the amount of current running through them. Tripping the circuit breaker interrupts the flow of electricity and protects your devices or appliances from damage.

Get FREE estimates from licensed electricians in your area today. Whether you need to replace an outlet, hang a ceiling fan, a new electrical panel, or repair wiring, We Can Help!

Without electrical circuit breakers , the possibility of electrical fires would be much higher.  

This guide looks at what causes circuit breakers to trip, what you can do, and how to identify a bad breaker.

What Would Cause a Circuit Breaker to Trip

There are three leading causes of circuit breaker trips:

• circuit overload
• electrical faults (i.e., ground faults and arc faults)
• short circuits

Below are factors that can cause circuit breaker trips. 

Circuit Overload

A circuit overload happens when the flow of electric current running through the circuit exceeds the amperage of the devices it serves. 

For example, if your microwave is a 12.5 amp appliance, you can run it on a 15 amp circuit. That means your microwave is safe as long as the amperage running through the circuit is 15 amps .

However, if the circuit receives an excessive electrical load over 15 amps , it will automatically trip to protect your device from damage. If the circuit doesn’t trip, the excess current will fry the circuit in your microwave. 

Also, if you operate too many appliances and devices on one circuit, its internal mechanism heats up, causing the breaker to trip. 

Circuit overload is the most common reason for breakers tripping. 

Ground Faults

A ground fault occurs when the active wire comes into contact with a ground wire made of bare copper. Sometimes, this fault may happen when the hot wire touches the metal box connected to the ground wire.

Excessive current flows once the active wire touches the ground wire, flowing into the earth. If you step on the affected area, ground faults can cause shock and even electrocution. The uncontrolled flow of electricity will cause the circuit breaker to trip.

Arc Faults 

An arc fault happens when exposed faulty wiring touches, causing the electric current to arc at the meeting point. As a result, sparks occur, which can ignite an electric fire.

A corroded or loose connection is the main culprit for arc faults. Circuit overloads, ground faults, or short circuits trip an AFCI (Arc Fault Circuit Interrupter) circuit breaker.

Arc faults result from damaged, loose, or corroded terminals and wires. The arc fault builds up over time as the heat due to the cable damage and terminals build up to the point of ignition.

Short Circuits

A short circuit occurs when an active wire touches a neutral wire, and the electrical current takes an unintended path of least resistance. 

The common cause of short circuits is frayed wires coming into contact when the wires touch. The electrical current flow increases significantly, causing the circuit breaker to trip to stop the electricity from damaging appliances.

It is a short circuit because the current bypasses the proper circuit wiring channels and flows through a shorter, unplanned pathway.

Short circuits occur 

• When insulation melts and wires are exposed
• Within appliances with damaged internal wiring
• Due to damaged and frayed extension or appliance cords

How do You Fix a Breaker that Keeps Tripping?

A dedicated circuit breaker tripping indicates too much current flowing through the wiring or connection to the outlet.

Here is a step-by-step guide to follow when you notice the first trip:

• Begin by turning off all the appliances and unplug electrical devices from the outlet. Also, switch off light fixtures and unplug those that you can. This prevents any appliances from damaged when the breaker is reset and a sudden surge of power comes through.
• Open the circuit panel or box and locate the on and off buttons of the circuit breaker. You may notice an orange or red color on the breaker when it is off. 
• Flip the switch from off to on to reset the circuit breaker. Once the breaker is reset, you can switch and test the appliances to see if the electrical power is flowing.
• Keep safe as you reset the breaker by working from the side of the electrical box instead of the front. That way, you will avoid any sparks (should there be any) when you switch the breaker back on.
• Some people prefer to switch the main electrical switch when working on the circuit breaker for added safety. 

Types of Circuit Breakers

Standard circuit breaker.

Standard circuit breakers monitor the modulation of the electric current coming into your devices and appliances. 

This circuit breaker stops the current from flowing when it detects the excessive flow of electricity. 

Standard circuit breakers come in two forms:

• Single-pole circuit breakers
• Double pole circuit breakers

Single-Pole Circuit Breakers

Single-pole circuit breakers are the most common breakers in homes and buildings. They monitor the electric current’s flow in one wire and trip if that wire experiences a very high influx of electricity.

These breakers deliver only 120 volts and work well for 15 to 30 amp circuits. Single-pole circuit breakers come with one switch in the back. 

Double-Pole Circuit Breakers

The double-pole circuit breakers monitor the current in two wires simultaneously. You will notice two switches on the back of these breakers.

The double-pole circuit breakers will trip even if only one of the wires receives too much current. They can accommodate between 15 to 200 amps while delivering 240 volts. 

Single-pole breakers are a good fit for lighting fixtures and other standard home outlets. On the other hand, double-pole breakers work for larger appliances like dryers and washing machines. 

Ground Fault Circuit Interrupter (GFCI)

The GFCI circuit breaker interrupts the line due to ground faults. They trip when the current starts to follow an uncharted path into the ground. These ground fault surges occur when a foreign conductor, like water, comes in contact with a receptacle .

At the same time, they offer protection against circuit overloads and short circuits. 

GFCI circuit breakers come built into specialized outlets required for wet areas in the home, including :

• Outdoor areas like the balcony, patio, porches, and decks
• Laundry rooms
• Swimming pools
• Six feet from a sink
• Six feet from the bathroom

These breakers help prevent shock or electrocution should the electrical outlet contact water. 

Arc Fault Circuit Interrupter (AFCI) 

The AFCI circuit breaker detects normal and abnormal arc faults, so it will trip when it detects a dangerous arc fault that can cause a fire. 

The AFCI circuit breaker doesn’t work to protect devices and appliances plugged into an outlet. It works to prevent electrical fires due to faulty connections and wiring. The internal sensing mechanism in the circuit breaker senses the conditions of an electric arc, and the circuit trips to avoid an electric fire.

AFCI protection can also be built into an outlet. The National Electrical Code (NEC) requires these types of breakers to feature in :

• Common rooms
• Laundry areas

AFCI and GFCI circuit breakers can co-exist and complement each other for the best protection.

Combination All Fault Circuit Interrupter (CAFCI)

The CAFCI breaker senses and reacts to any electrical fault, including ground and arc faults.

CAFCI is a relatively new technology that meets new NEC requirements for circuits requiring arc and ground fault protection.

Do Circuit Breakers Get Weak?

A circuit breaker can wear out and become weak. If a breaker trips frequently, the thermal or magnetic element can lose calibration, causing it to trip at lower amp loads than intended. A breaker constantly under thermal stress caused by overloading the circuit will eventually trip more frequently.

Let’s not forget breakers are not impervious to damage. As the internal mechanical parts wear out, they become very sensitive and may not hold under normal load amperage and temperatures.

Electricians refer to this as a bad breaker .

Will a Bad Breaker Keep Tripping

By definition, bad breaker malfunctions, so it will keep tripping until it is either replaced or rectified .

A licensed electrician performs this simple test to see if a breaker will keep tripping and determine if it can be repaired or replaced in the following steps.

• The electrician will switch off all the fixtures and appliances in the house. Also, unplug everything.
• Find the malfunctioning circuit breaker . The electrician will go to the electrical box and locate the breaker lighting orange or red or the one with the switch off.
• They will ascertain that it is the correct circuit breaker. After that, the electrician puts the breaker off.
• With the switch on, the breaker is back on as well. The electrician will plug the appliances into the outlet with the problem circuit breaker. Now, they will turn the devices and appliances on. 

If the breaker trips, the electrician will investigate the circuit’s current amount. The breaker is bad if the current is according to the appliance’s rating.

How You know if a Circuit Breaker is Bad

Breakers do wear out after a while. It has a problem if the breaker doesn’t stay on after resetting it.

Since the circuit breaker controls the electric flow in the house, it is essential to monitor it and catch signs that it has gone bad early.

Here are key signs that denote a bad circuit breaker :

It Frequently Trips

Frequent tripping could be because of a bad breaker. After tripping and resetting, your circuit breaker should stay on unless it detects high current flow. 

To ensure that the issue is not the electricity but the circuit breaker, call an electrician to examine your electricity’s flow and determine whether it is the cause of the constant tripping.

If it is not, then the circuit breaker is the problem. 

The Breaker Overheats

Electrical systems will heat up when active. Typically a breaker can heat to about 60°C (140°F) before problems arise.

Terminations for standard rated breakers: UL 489 Paragraph 7.1.4.2.2 says the temperature rise on a wiring terminal at a point to which the insulation of a wire is brought up as in actual service shall not exceed 50°C (122°F). Terminations for 100% rated breakers: UL489 Paragraph 7.1.4.3.3 says the temperature rise on the termination shall not exceed 60°C (140°F). Handles, knobs, and other user surfaces: UL489 Paragraph 7.1.4.1.6 says the maximum temperature on handles, knobs, and other surfaces subject to user contact during normal operation shall not exceed 60°C (140°F) on metallic and 85°C (185°F) on nonmetallic surfaces.

Call an electrician immediately if the breaker becomes too hot.

There are Scorch Marks

Scorch marks around receptacles, appliances, and the electrical box should tell you your circuit breaker has gone bad.

The burn marks indicate that wiring insulation has melted off and the circuit wires are now sparking and emanating heat or fire. That means that the circuit breaker did not interrupt the excess current and reached the wires and burned them. 

You may see melted wire sheathing on the wire where it connects to the breaker.

Professional electricians can use a  thermal imaging infrared camera to locate the heat source. The infrared camera allows them to pinpoint the problem area through the walls and other construction material.

A Burning Smell

Sometimes you may smell the insulation burning, but no scorch marks are present to denote which outlet is the problem. 

With the help of the infrared camera, an electrician can help locate electrical issues. 

If you encounter a burning odor, shut off the main power and call for emergency service from an electrician. 

The electrical wires burn because power surges through the circuit, melting the wire insulation.

What is Nuisance Tripping

Nuisance tripping is when a breaker trips without a fault to warrant the interruption to the electric current flow.

Nuisance tripping occurs due to several reasons:

Stringent Protection on Circuits 

Sometimes the circuit is protected by stringent conditions that detect any variance as a fault and cause a trip. 

Such stringent conditions can be tuned to accommodate the home’s or building’s electric needs.

A Highly Sensitive Circuit Breaker

In some cases, the circuit breaker has been set to susceptible settings so that they can detect even the slightest fault, even a minor average variance.

For example, the manufacturer can set an AFCI circuit breaker to sensitive standards to detect another circuit’s arc. This common issue may occur in a daisy chain where the circuit breakers connect in a linear series. There may be a faulty electrical outlet you are unaware of on the circuit. It is common for multiple rooms to share a breaker in older houses.

The Breaker Encounters Power Under Different Conditions

The variation in the current is normal, but the breaker responds to it by tripping because the flow is outside the breaker’s regular operation.

Your circuit breaker is tripping because the voltage it is encountering is not within the standard operation. You will need to adjust the circuit breaker or the voltage to eliminate nuisance tripping.

The Breaker Trips with Nothing Plugged in

A breaker tripping with nothing plugged in occurs when a hot, neutral wire is touching somewhere in the circuit. The common causes include frayed or damaged electrical wires, loose connections, faulty electrical receptacles, light switches , or dimmers.

Electrical wire damage happens when:

• wiring is chewed by animals such as rats, squirrels , raccoons, etc
• wire sheathing and insulation ages and become frayed
• wires rub against sharp edges such as punch-outs with missing grommets or wire clamps

Loose connections often occur when electrical wire nuts come loose or electrical tape wears out causing wires to touch.

Defective wiring can be anywhere along the circuit, so it’s best to contact a licensed electrician to troubleshoot why the breaker is tripping.

Replacing a Bad Circuit Breaker

• Check the electrical panel to see the compatible approved circuit breaker brands. Also, make a note of the brand of the electric panel . This is to help you determine if there are upgrades they could recommend for the hardware.
• Order online or go to the hardware store and purchase the breaker of the same voltage as the one you are replacing.
• Go and open the electrical box and switch off the bad breaker. Loosen the terminals and remove the wires using a pair of needle-nosed pliers. Ensure the pliers have rubber insulated handles to avoid shock or electrocution since you will use the pliers to grab the live wires from the terminal. That is a safety measure.
• Remove the bad breaker. Replace it with the new breaker and slip its clips into place. Remember to switch off the replacement breaker.
• Next, using the pliers, hold the wiring and tighten the screws on the terminal. It is crucial to ensure that the wires and screws in the terminals are in the right place.
• Turn the breaker on and replace the electrical panel cover.

Can a Breaker Fail Without Tipping

If you have a newer electrical panel , it’s not likely for a breaker to fail and not trip. However, in older breaker boxes like Federal Pacific , the breaker failing to trip is common.

The main reason Federal Pacific was investigated by the Consumer Products Safety Commission (CPSC) was widespread structure fires involving breakers failing to trip when an electrical overload was present. They found that the circuit breaker contacts would fuse to the bus bar.

Modern breakers will trip when a failure occurs as an added layer of safety. Most older breakers did not have these safeguards.

With AFCI breakers, if the Internal sensing mechanism fails, the breaker reverts to a standard breaker. The AFCI sensor mechanism will no longer work, but the breaker would still trip from overcurrent protection. Therefore, you should test the AFCI breaker regularly.

Conclusion 

Listen to your circuit breaker . It’s alerting you of a problem when it trips. That communication could be a problem with the breaker itself, the circuit, or the amount of electric current coming into your home.

What Causes Circuit Breakers To Trip?

• April 2, 2024

If your circuit breakers keep tripping, there’s no need to stress. This is a typical situation. Below, you’ll find details on the reasons behind this and tips for avoiding it going forward. Get a handle on your circuit breaker issues!

Table of Contents

Understanding Circuit Breaker Tripping

Circuit breakers are protection devices for electrical circuits. When too much current passes, the breaker trips, stopping the flow of electricity and preventing damage. This can be caused by faulty wiring, too many appliances on one circuit, or a ground fault.

Overloading can cause tripping. This happens when too many devices are connected to a single circuit. Heat builds up in the wires, which can start fires or cause damage. To prevent this, distribute loads across multiple circuits and don’t connect too many appliances to one outlet.

Short circuits also lead to tripping. This happens when two wires with opposite charges come in contact or when a wire touches something grounded. This causes an immediate surge in current that triggers the breaker. Check for exposed wires or insulation damage, and call an electrician if you spot any signs of trouble.

Ground faults can also cause tripping. This happens when there’s an unintentional connection between a live wire and a conductive surface. Install GFCIs to avoid this.

In short, know what causes circuit breakers to trip. Identify potential hazards like overloading, short circuits, and ground faults. Take steps to prevent accidents and ensure your electrical equipment is safe. If you’re unsure how to handle electrical problems, call a licensed electrician.

Overloading Causes

Circuit breakers trip to stop overheating, electrical fires, and damage to electrical parts. Plugging in too many devices can cause the circuit to become overloaded, so the breaker trips to cut off the power.

Short circuits are like a blind date gone wrong. They can be explosive, and often end in disaster. This happens when a hot wire comes into contact with a neutral or insulation/water. This throws off the electric balance, causing danger and tripping.

Short Circuit Causes

A short circuit happens when a low-resistance path appears between two points in the circuit that aren’t usually connected. This can cause too much current to flow, making a circuit breaker trip. Insulation or wiring damage, faulty appliances, and circuit overload are the most common reasons for a short circuit. It’s critical to identify and fix the root cause quickly to avoid electrical fires and other dangers .

When too much power passes through a circuit, the circuit breaker will automatically turn off. It’s designed to protect wiring and guard against electrical accidents . But if the breaker trips regularly, there may be underlying issues that need investigation and repair. Often times, this means upgrading or replacing components.

Sometimes short circuits are caused by human error or wear and tear. But they may also come from design or installation problems. Planning and upkeep from local electricians can keep electrical systems running safely and appropriately for a long time. If your circuit breaker is tripping a lot, get an experienced technician to review your system and suggest solutions that match your needs and budget .

Overheating Causes

Circuit breakers are essential safety features. They stop electrical fires and protect your appliances. When overloaded, too much current flows, producing heat. This causes the breaker to trip!

Other factors can cause overheating. Damaged insulation on wires increases resistance. Loose connections add resistance and heat. High temperatures and poor ventilation worsen the situation.

It’s important to maintain and service the electrical system. Checks of all components will make sure they work efficiently. To avoid tripping, prevent overheating. This will reduce energy consumption and safeguard equipment. So, let’s learn about circuit breakers and how they deal with overloads!

Circuit Breaker Types

Circuit breakers are essential for any electrical system. They prevent overloaded and faulted circuits . There are different types of circuit breakers suitable for specific electrical loads.

See the table below for the different types of circuit breakers and their functions:

It is crucial to select the right type of breaker. Each one has its own advantages in specific situations. For instance, thermal circuit breakers are perfect for small appliances like hair dryers or irons . Meanwhile, magnetic circuit breakers are great for bigger loads such as air conditioners or refrigerators .

Remember, circuit breakers are like Beyoncé – they can handle a lot, but have their limits.

Circuit Breaker Ratings and Specifications

Circuit breakers are designed to protect electrical circuits from overloads. To ensure that circuits and appliances are safe, the ratings and specifications of circuit breakers need to be understood.

If a circuit breaker trips often, it may mean there’s an issue. It’s best to get professional help in these cases. Time to go on a hunt for your electrical wiring!

Troubleshooting Circuit Breaker Tripping

Circuit breakers can flip out for multiple reasons, like overloads , short circuits , and ground faults .

Overloads happen when too much electricity passes through the circuit, creating too much heat and tripping the breaker. Short circuits are when two or more wires touch, resulting in extra current. Ground faults occur when the power takes an unexpected route, like through a person’s body.

To figure out why your circuit breaker is tripping, it’s important to figure out what is going on and act accordingly. Inspections and maintenance can also help avoid future tripping.

Stop your circuit breaker from misbehaving with these prevention tips!

Preventing Circuit Breaker Tripping

A circuit breaker tripping can be prevented with understanding. When circuits are overloaded, breakers trip to avoid overheating and potential fires. Here are 3 steps that can help you prevent circuit breakers tripping:

• Know the electrical load – work out how many appliances & devices are connected to one circuit. Don’t overload them by spreading high-energy equipment across multiple circuits .
• Look after your appliances – ensure all your appliances & devices are in good condition, with no damaged cords or frayed wires.
• Upgrade your system – if you’re tripping breakers often you may need to upgrade the electrical system with higher capacity breakers or more circuits.

Plus, investing in surge protectors can also assist in preventing circuit overload and subsequent tripping of breakers. By following these steps you can make sure your home’s electricity runs safely and without interruption due to circuit breakers tripping.

Remember: these precautions will keep you from tripping more than just your circuit breakers!

Safety Precautions

Safety must be taken seriously when dealing with circuit breakers . Always switch off the main power supply before beginning work. Wear protective gear such as insulated gloves and boots to stay safe from electrocution. Never touch wires or components inside the box without proper training. Keep the area around the breaker box free from any flammable substances. Inspect breakers for damage or wear regularly .

Label each circuit breaker correctly . Test them frequently for functionality. This will help identify circuits quickly in case of an emergency. These precautions and practices ensure safety while dealing with circuit breakers. When in doubt, blame it on the circuit breaker – it’s always a good scapegoat for electrical woes!

Circuit breakers are essential components of any electrical system. They stop too much current flowing and thus, protect against potential fires . The most common cause for tripping is overload. But, other causes like short circuits and ground faults can also cause the breaker to trip. When it trips, there is something wrong that needs to be fixed right away.

Short circuits occur when two wires touch each other. This creates a low resistance path which allows a lot of current to flow with no load. Ground faults occur when the hot wire touches something incorrectly wired or with a damaged cord.

To prevent tripping, regular maintenance of the electrical system is needed. Keeping appliances in good condition, replacing worn-out cords and fixtures, and periodically checking for loose wires all help reduce the chances of tripping. In summary, understanding why the breaker trips and taking precautionary measures will keep you safe and save you repair costs.

Why Does My Circuit Breaker Keep Tripping?

The circuit breakers in your house or building are there to protect you from the dangers of electrical faults. Still, it can be pretty stressful when one of those breakers repeatedly trips, no matter how many times you try to turn it back on.

When your circuit breaker trips, that means there’s an electrical fault in the circuit it protects. You can fix it by troubleshooting all appliances and electrical components on that circuit. For example, a device is likely faulty, or there’s damage to wall sockets and electrical wiring. Once you resolve the root cause, you can turn the breaker back on.

Unfortunately, troubleshooting a tripping circuit breaker isn’t always straightforward. Don’t worry, though. This guide will teach you to fix the problem much more effectively.

Is It Dangerous If A Circuit Breaker Keeps Tripping?

Table of Contents

Yes, it’s very dangerous if you have a circuit breaker that keeps tripping.

To know why you must first understand the purpose of that circuit breaker. You see, it’s very dangerous when too much electrical current flows through a circuit. So, a circuit breaker is added to that circuit to prevent that from happening.

Excessive current in the circuit will cause the breaker to trip. As the name suggests, that will break the circuit and stop the flow of electricity entirely.

However, if your circuit breaker keeps tripping, that means there’s an ongoing electrical fault somewhere on that circuit. 

For example, there could be a fault in the appliance or their wiring.

Until you fix the fault and stop the circuit breaker from tripping, you run the risk of:

• Electrocution to anyone handling any part of that circuit.
• Electrical fires could spread throughout the house or building.
• Damage to any appliance on that circuit, requiring expensive replacements and repairs.

So, when you have a tripping circuit breaker, you must resolve it immediately. You should only fix it yourself if you have the necessary skills. If not, be sure to call a qualified electrician.

How To Find What Is Tripping My Circuit Breaker?

Finding the root cause behind your tripping circuit breaker will require a bit of detective work on your part.

Use this 3-step process to find the root cause:

Step 1: Identify The Affected Circuit

First and foremost, you must identify the affected circuit, which the tripping circuit breaker protects.

To do that, start at the main electrical box and open the panel. That’s where you’ll find all of the circuit breakers for your home or building.

In some cases, you’ll find that each circuit breaker has a clear label telling you what it’s for. If that’s the case, you’ll have a much easier time finding the root cause of the problem.

However, if there are no labels, you’ll have to test them manually. Reset the circuit breaker and see which appliance or part of your house turns on. Pay attention to when it trips and see which parts of the house no longer have electrical power.

Once you identify the affected circuit, you can then troubleshoot the electrical components and appliances in that part of the house.

Step 2: Check All Electrical Outlets And Appliances On That Circuit

Let’s suppose that the tripping breaker is for your kitchen’s electrical circuit. In that case, you’ll have to check the electrical components and appliances in that part of the house.

What you’re looking for are signs of electrical damage or faults. 

For example, look for burning smells or burn marks on your appliances and plugs. 

Step 3: Test Individual Appliances And Look For Patterns

You’ll have to go through a lot of trial and error for this troubleshooting process. For example, suppose you suspect that a specific appliance is causing your breaker to trip. In that case, it’s best to test it on another circuit.

For example, plug your toaster into a wall socket at another part of the house. When that causes a different circuit breaker to trip, you’ll know that the appliance is to blame.

Besides that, look out for patterns when the breaker trips. For example, do you notice it tripping whenever the fridge compressor turns on? That’s a clear sign that you should get a technician to troubleshoot the fridge instead.

How To Fix A Breaker That Keeps Tripping?

Sometimes, it’s not an appliance that’s causing your circuit breaker to keep tripping. So once you rule out any problems with your devices, here are a few other things to consider.

Why Does My Breaker Keep Tripping With Nothing Plugged In?

Try not to get frustrated when your circuit breaker trips even with nothing plugged in. Once you’re sure that none of your appliances are on, you’ll have to troubleshoot for:

• Short circuits caused by problems with your electrical wiring.
• Excessive currents, like from power surges during thunderstorms.
• Ground faults, when a live electrical wire touches the ground.
• Faulty circuit breakers, if you have old circuit breakers at the end of their useful lifespan.

Troubleshooting the above can be pretty risky if you’re not sure what you’re doing. So, again, don’t be afraid to contact an electrician to do it for you.

Why Does My Circuit Breaker Trip Only At Night?

As you’ve seen in earlier parts of this guide, troubleshooting a tripping circuit breaker involves trial and error, as well as spotting patterns.

So, if your circuit breaker keeps tripping at night, focus your attention on appliances that only run during that time.

For example:

• Do you have automatic lights that only turn on at night?
• Do you have an HVAC (heating, ventilation, air conditioning) system that runs at night?
• Do you have computer systems or similar equipment that run at night?

Once you narrow down the appliances that might cause the circuit breaker to trip only at night, troubleshoot them one at a time using the same steps described above.

For example, you can plug the appliances into different circuits in your house to see if they trip other circuit breakers instead.

Why Does My Circuit Breaker Trip After 30 Minutes?

After resetting a tripped circuit breaker, you might find that there’s a slight delay before it trips again. That delay could be 30 minutes or even a few hours before the breaker predictably trips again.

The reason that happens is that the circuit is overloaded but only barely over the circuit breaker’s limit. In other words, there is an electrical fault, but not enough to instantly trip the circuit breaker.

As a result, the breaker is constantly on the verge of tripping. Still, it often takes a bit of time before that happens.

So, whether your circuit breaker takes 3 minutes or 30 minutes to trip, you must troubleshoot the circuit using the same steps described above.

In short, you must check for electrical faults in:

• All appliances plugged into that circuit, like lights, TVs, kitchen equipment, and anything else.
• All power sockets and switches on that circuit, including wall switches and wall outlets that you plug appliances into.
• All electrical wiring for that circuit, which might have suffered burns or been chewed through by pests.

How Do You Reset A Tripped Breaker?

Resetting a tripped circuit breaker is very straightforward.

First, you must understand that a standard circuit breaker has 3 positions:

• ON: On one side, you have the ON position. That means the electrical current will flow through the breaker and the circuit.
• OFF: You can push the breaker to the OFF position on the other side. That will stop any electricity from flowing in the circuit.
• Center: More importantly, you have the center position. When your circuit breaker trips, it will not go to the OFF position. Instead, it’ll go to the center to indicate that it tripped and was not shut off on purpose.

Do not push the switch from the center to the ON position to reset a tripped breaker. Instead, do this:

• Firstly, move the switch to the OFF position.
• Secondly, move the switch all the way to the ON position.

When The Tripped Circuit Breaker Won’t Reset:

When you try to reset your circuit breaker, but it trips instantly, that’s a telltale sign that there’s a short circuit.

Do not try to force the circuit breaker to stay on. Instead, you must troubleshoot the circuit and fix the root cause first.

When The Breaker Keeps Tripping After Reset:

Suppose you successfully reset the circuit breaker, but it trips soon after. In that case, you likely have a ground fault in the circuit.

That’s when the electricity flows straight to the ground instead of going through the circuit normally. Again, you must resolve the root cause of this issue before you can turn your circuit breaker back on again.

Dealing with a circuit breaker that keeps tripping without any load can be frustrating and worrisome.

If you find yourself constantly resetting the breaker without a resolution, it is crucial to understand the underlying causes and discover effective solutions.

In this comprehensive guide, we will explore common wiring problems that lead to breaker trips and provide expert guidance on how to address them.

By understanding and rectifying these issues, you can ensure a safe and reliable electrical system in your home or building.

Let's dive into the reasons behind circuit breaker trips without load and learn how to resolve them.

Understanding Why Your Circuit Breaker Keeps Tripping Without Load

To effectively address the issue, it is important to understand why your circuit breaker keeps tripping.

Although it may seem like there is no load present , there is always some electrical load in the system. This is because components such as capacitors, diodes, and transistors continuously conduct small amounts of current, even when devices are turned off.

Therefore, the notion of tripping without load is actually inaccurate. The key question is, what is causing the circuit breaker to trip despite minimal or no additional load?

Wiring Problems Leading to Circuit Breaker Tripping:

Several wiring problems can contribute to circuit breaker trips without load. Let's explore the three most common issues and their solutions:

Current Leakage:

One potential cause is current leakage, where one or more input wires experience small amounts of current flow. Although this can be frustrating, it is actually a safety precaution to protect against electrical hazards.

To address current leakage , it is crucial to identify the source of the leakage. This may involve inspecting the insulation, wire jackets, and connections for any signs of damage.

Seeking assistance from an electrician can help diagnose and rectify current leakage issues, ensuring a safe electrical system. 

Damaged Wires:

Damage to the wiring can also result in circuit breaker trips without load.

Insects or other pests may have caused significant damage by chewing on the wires. Even under low loads, such damage can disrupt the electrical flow and trigger the breaker.

Resolving this issue requires a thorough inspection of the wiring system. Identifying any areas with frayed, exposed, or damaged sections and repairing or replacing the affected wires will help restore proper functionality and prevent future trips.

Loose Wire in an Outlet:

A loose wire in an outlet is another frustrating wiring problem that can cause frequent breaker trips. This issue is particularly common in outlets equipped with a GFCI Outlet .

A loose wire disrupts the electrical connection and prompts the breaker to trip repeatedly.

Resolving this problem requires replacing the outlet or repairing the wiring connection. It is crucial to seek the expertise of a qualified electrician to ensure the task is performed safely and accurately.

Seeking Professional Assistance

While the provided solutions are applicable to a circuit breaker tripping without load, it is important to seek professional assistance if the problem persists.

A certified electrician can conduct a thorough inspection of your electrical system to identify any underlying issues.

They may recommend load balancing techniques, upgrading the electrical infrastructure, or addressing other potential causes of breaker trips. By relying on their expertise, you can prevent future disruptions and ensure a stable electrical system.

Preventing Circuit Breaker Tripping

Implementing preventive measures can significantly reduce the likelihood of circuit breaker trips without load. Consider the following steps: 

Regular Maintenance:

Schedule periodic inspections and maintenance of your electrical system by a certified electrician. They can identify potential wiring problems, loose connections, and other issues before they escalate. Regular maintenance helps keep your electrical system in optimal condition, minimizing the risk of breaker trips. 

Proper Grounding:

Ensure your electrical system is properly grounded. Grounding provides a safe path for electrical current in the event of a fault, reducing the likelihood of circuit overloads and breaker trips. A professional electrician can verify and enhance the grounding system if needed. 

Evaluate Electrical Appliances:

 Periodically assess the electrical appliances and devices connected to your circuits. Older appliances may draw excessive power, leading to breaker trips. Consider upgrading outdated or energy-inefficient appliances with newer, more energy-efficient models. This not only reduces the risk of breaker trips but also lowers energy consumption and utility costs.

Install Dedicated Circuits: 

If you have high-demand appliances or equipment that consistently cause breaker trips, consider installing dedicated circuits. Dedicated circuits provide exclusive power sources for specific appliances, minimizing the chances of overloading and tripping the breaker. Common examples include refrigerators, air conditioners, and washing machines. Checking your breakers and circuits using a circuit breaker finder can be helpful.

Educate Household Members: 

Promote awareness and responsible electricity usage among household members. Encourage them to evenly distribute electrical loads, avoid overloading circuits, and promptly report any electrical issues. By practicing safe electrical habits collectively, you can prevent unnecessary breaker trips and maintain a stable electrical system.

Dealing with a circuit breaker that keeps tripping can be frustrating. However, by understanding the underlying causes, such as current leakage, damaged wires, and loose connections, you can take appropriate steps to effectively resolve the issue.

Remember, electrical repairs should always be entrusted to experienced professionals to ensure safety and prevent potential hazards. Once the necessary repairs are completed, you can enjoy a stable electrical system, free from the inconvenience of frequent breaker trips.

Proactive maintenance, periodic inspections, and timely repairs will help ensure the smooth functioning of your circuit breakers, promoting a safe and reliable electrical environment in your home or building.

By addressing wiring problems promptly and following preventive measures, you can minimize the likelihood of circuit breaker trips without load and maintain a well-functioning electrical system.

How can you fix a breaker that keeps tripping?

To resolve a breaker that keeps tripping, follow these steps: 

- Identify the cause: Determine if the breaker is tripping due to an overload, short circuit, or ground fault. This will help you address the specific issue effectively.

- Unplug devices: If overloading is the cause, unplug some devices from the circuit to reduce the electrical load.

- Reset the breaker: After unplugging devices, reset the tripped breaker by flipping it to the "off" position and then back to the "on" position. This should restore power to the circuit.

- Distribute loads evenly: If overloading is a recurring problem, redistribute the electrical loads across multiple circuits or consider installing dedicated circuits for high-demand appliances.

- Consult a professional: If the breaker continues to trip or if you suspect an underlying wiring issue, seek the assistance of a qualified electrician. They can diagnose and resolve the problem safely and effectively. 

What causes a breaker to trip repeatedly?

A breaker can trip repeatedly due to various reasons, including:

- Overloading: When the electrical load on a circuit exceeds its capacity, the breaker trips to prevent overheating and potential fire hazards.

- Short circuits: A short circuit occurs when the hot wire comes into direct contact with the neutral wire or ground wire. This can result in excessive current flow and cause the breaker to trip.

- Ground faults: Ground faults occur when a hot wire comes into contact with a ground wire or a conductive surface. This can also lead to excessive current flow and trigger the breaker.

- Wiring issues: Damaged or faulty wiring, loose connections, or faulty breakers themselves can cause repeated trips.

Identifying the specific cause is crucial to effectively addressing the issue and preventing future trips. 

Is a breaker bad if it keeps tripping?

Not necessarily. While a breaker that keeps tripping can indicate an underlying problem, it does not necessarily mean that the breaker itself is faulty. Breakers are designed to trip and interrupt the electrical flow when they detect potential dangers like overloads, short circuits, or ground faults. This is a safety feature intended to protect the electrical system and prevent hazards.

However, if a breaker consistently trips even when the electrical load is within the circuit's capacity, it could indicate a faulty breaker that needs replacement. A qualified electrician can assess the breaker's condition and determine if a replacement is necessary.

Remember, it is important to consult a professional to diagnose and resolve breaker tripping issues, ensuring the safety and proper functioning of your electrical system.

What to Do If Your Circuit Breaker Trips

Basically, electric current flows into your home into the breaker box (usually built in the garage or in the basement in the home) where it’s split into a number of circuits and sent throughout the house.

For rooms that only need electrical power for small things like lighting fixtures and televisions, you usually only need 15-amp circuits. For rooms with bigger appliances, such as the kitchen or bathroom, you’ll usually have 20-amp circuits. Certain appliances, like the oven or dryer, are so power consuming they need 30 – 50-amp circuits all to themselves! When it is said that a circuit breaker “trips,” it means that circuit has detected what’s known as a fault condition and has shut itself off to prevent the wiring from overheating and potentially igniting itself.

Resetting a tripped circuit breaker is generally pretty easy – you just need to go back to the electrical panel, find the circuit that’s not facing the same direction as the rest and flip it back to it’s original setting. If the breaker trips again right after you do this, that’s a problem – you’ll have to figure out the cause of the problem before you can fix it.

If your circuit breaker trips right after being reset, you could be facing one of three issues:

•  an overloaded circuit
•  a short circuit
•  a ground fault

Overloaded Circuit

An overloaded circuit is the most likely problem that would make your breakers trip. In simple terms, it means there is more current flowing through the circuit than it is made to carry, so it shuts off to stop any damage.

Remember earlier when we spoke about the different levels of current certain rooms in your home receives? When you are searching for an overloaded circuit, try finding any appliances on the overloaded circuit that would be using more electricity than the circuit would allow. Pay extra attention to objects such as space heaters, toasters, hair dryers straighteners, etc. – These things tend to consume the most power.

The solution for overloaded currents is pretty simple – just unplug things you’re not using! If this doesn’t solve the issue, call an electrician – you may have loose connections somewhere in the house, though this is pretty rare.

Short Circuit

If the problem is not being caused by an overloaded circuit, most likely a short circuit is the issue. Short circuits are a slightly more serious problem than overloaded circuits, which happens when the hot (black) wire touches another hot wire or a neutral wire. The surest way to tell if you are having a short circuit is to first check your power cables for damage or a melted covering (make sure the appliance is unplugged first)  and to check the power outlets or plugs for discoloration or a burning smell. If you can’t locate the problem, hire an electrician to take a look at it.

Ground Fault

If you’ve looked at the two other possibilities and checked for problems, but you don’t think you have an overloaded or a short circuit, you should check to see if a ground fault is causing your troubles. A ground fault exists when the hot (black) wire touches the ground (bare) wire or the walls of a metal outlet box. If you have a ground fault, it’s best to have a  Vancouver electrician take care of the problem.

New porch light trips breaker after 30 minutes or so

• Add to quote

I replaced our porch light with a new fixture yesterday. After having the porch light turned on for maybe 30 min to an hour, it went out. I go check the breaker box and the circuit is tripped. I flip it off and back on, go turn on the porch light, works fine. However, I didn't want to leave it on overnight worried it may cause issues. After doing some research, it seems like it's probably a circuit overload. If it were a short circuit, it seems like it would trip immediately after turning it on, so I am assuming it's the former and there are just too many amps running. If that's the case, why wouldn't the old porch light have tripped the breaker? Isn't the amps related to the outlet and not the fixture? I am using 5w LED bulbs x 3 in the new fixture. The old porch light only had 1 of 3 bulbs working (why I replaced it) so it would only have one bulb going instead of 3. Could that be my issue? Just wondering if I should look for a different fixture or if it matters. Or do I hire an electrician to redistribute the load of that specific circuit? Other options? Any advice is appreciated, thank you!  

Is the breaker AFCI or a regular breaker? What is it's amperage. What else is on the circuit?  

The fixture and bulbs determine the load. Three 5w leds would be a very small load.  

circuit tripped, means what? Breaker tripped? GFCI breaker tripped? GFCI outlet tripped? By tripped the handle is in the middle position? You must force it off and then back on?  

Sorry yes, the breaker tripped at box. Not sure amps on breaker but there are a number of things on the same breaker... basement lights.. stair lights... other room lights...etc.  

Look on the switch handle of the breaker. It will tell you the amperage.

Check your new work first, if wires are heating they can move to where they can short. Check your connections  

Shut off all the other loads and see if the lights stay on without tripping the breaker.  

Yes it runs fine by itself so far...2 hours in.  

I would replace the light again. The problem started after you changed the light. I had this issue one on my fathers house. Replace both lights on the front of garage and they would trip the breaker after about an hour. Replaced them with a different light and never had an issue again.

What is a circuit breaker?

A circuit breaker is an automatic switch that interrupts electrical flow when there is a fault or overload in the system. It is designed to protect electrical circuits from damage by cutting off power when the current exceeds a certain level.

We can define a circuit breaker as  “A circuit breaker is an automatic switch that interrupts electrical flow when there is a fault or overload in the system. It is designed to protect electrical circuits from damage by cutting off power when the current exceeds a certain level”.

How does it help the electrical circuit?

Circuit breakers help to prevent electrical fires by interrupting the flow of electricity when there is an overload or short circuit. They also help to protect electrical equipment from damage by cutting off power when there is a fault in the system. This helps to save money on repairs and ensures that your equipment lasts longer.

This image gives an idea about the working of breakers in the wiring.

Circuit breaker trips at night:

It can be very frustrating when your circuit breaker trips at night, especially if you are not sure why it is happening. Here are some common reasons why circuit breakers trip at night:

• Overloaded circuits:

An overloaded circuit is the most common reason why circuit breakers trip at night. This happens when you have too many electrical devices or appliances running at the same time, and the circuit cannot handle the load. As a result, the circuit breaker trips to prevent damage to the system.

• Short circuits:

A short circuit occurs when the hot wire touches the neutral wire, creating a direct path for electricity to flow. This can cause the circuit to overload and trip the breaker.

• Faulty appliances:

Faulty appliances can also cause circuit breakers to trip at night. This is because they can cause a short circuit or overload in the system, which can trip the breaker.

Should I worry if the circuit breaker trips at night?

If your circuit breaker trips at night, you should not panic. It is a common occurrence, and it does not necessarily mean that there is a serious problem with your electrical system.

Why is My AC Tripping the Circuit Breaker?

October 04, 2021

Air conditioners are vital to Floridians, so it's no surprise that homeowners would be stressed if their AC suddenly started turning off.

If this is happening to you now, it’s likely a tripped circuit breaker. When your AC trips the circuit breaker after running for only a few minutes, your breaker cuts the power to the AC system.

Why is your AC tripping the circuit breaker? Many issues can be at play, but the primary 3 reasons include:

• An overloaded circuit
• A grounded compressor
• A faulty breaker

We’ll review how to reset your circuit breaker to see if that restores your AC’s power. If it doesn’t, we’ll dive into the potential problems related to a tripped circuit breaker and how to troubleshoot them.

Want a professional to identify and fix your AC’s tripped circuit breaker? Contact Advanced Air for an AC repair . We provide punctual and round-the-clock service .

Reset your circuit breaker

Reset your circuit breaker to see if it stops tripping

Before we look at what could be causing the frequent tripping, let's first try resetting the circuit breaker. You can do so by:

• Let the unit cool down for about 5 minutes. The Department of Energy recommends letting the unit rest before resetting any breakers.
• Turn off your thermostat.
• Locate your gray main circuit panel by checking your closets, garage, or basement. Make sure there's no water on the ground in the room with the panel. If there is, do NOT stand in the water while resetting the breaker.
• Find the AC switch. The breakers are typically labeled. If not, look for the switch that is either in a middle position or OFF. Some manufacturers have a visible color indicator that shows that a breaker has tripped.
• Push the switch OFF unless it's already OFF. If already OFF, skip to Step #6.
• Push the switch ON. You should feel a satisfying click into place.
• Wait for 30 seconds.
• Turn your AC back on to test.

If your AC immediately trips again, do NOT reset the breaker again until the cause is corrected. Multiple overcurrents, or surges of electricity, can damage your AC and even start a fire.

Read on to learn about the potential issues causing your AC to trip the circuit breaker.

Three main reasons behind your AC tripping the circuit breaker:

1. an overloaded circuit.

Circuit breakers shut off the flow of electricity whenever the number of amps (a unit of electrical current) exceeds its amp rating. For example, if the circuit breaker has a rating of 15 amps, it'll trip whenever 20 amps flow through the circuit.

So, whenever your AC is using too much energy, it's pulling in more amps than usual, causing a surge and your circuit breaker to trip.

Your air conditioner can use too much energy if:

The air filter is dirty:

An Advanced Air technician can help you replace your filter

Air conditioners need air to be flowing into the system to cool your home enough to meet your set temperature.

When air filters get clogged with debris and dirt, they block airflow from entering the system. Your AC now has to compensate by working harder and using more electricity to cool your home. The circuit breaker isn’t used to this amount of energy consumption and trips to protect your AC.

The condenser is dirty:

Our technicians can help clean your condenser

Your AC's outdoor unit is called the condenser. It plays an essential role in keeping your home cool by dumping the heat your indoor unit absorbs from your home's air outside.

When the condenser is dirty or blocked by bushes, your outdoor unit can no longer effectively transfer the heat outside, and your AC has to use more energy and take longer to cool your home. This increase in needed power trips the circuit breaker.

The condenser fan doesn't work correctly:

As we mentioned above, the condenser is your outdoor AC unit. The condenser's fan helps dissipate heat back outside. If you stand next to the condenser and can't hear the fan rumbling, it's likely broken.

When the fan’s motor is broken or worn out, the electricity from your AC system to the motor has nowhere to go and is flowing freely. Your AC will automatically detect this issue and trip your circuit breaker to prevent the wires from frying and damaging your system or home.

The refrigerant is leaking:

What is refrigerant? It's a cold substance in your AC that helps the indoor unit absorb heat from the air. Leaking refrigerant means your AC can't cool your home as effectively due to reduced heat absorption abilities, forcing it to use more power and tripping the breaker due to overload.

How do you know you have a refrigerant leak? You can tell when:

• You see ice forming on the condenser
• You hear hissing or bubbling noises coming from your inside AC unit
• You have higher than normal monthly energy bills

Advanced Air technicians can diagnose the problem behind your circuit tripping

If you suspect your breaker keeps tripping because of any of these reasons, try changing out your air filter monthly and booking an appointment with an AC technician to clean the condenser. Also, make sure to check your condenser's fan and inspect the refrigerant lines.

2. A shorted compressor

Typically, electricity flows in a loop called a circuit. When a compressor "shorts," it's because a malfunction interrupts the loop, allowing too much electricity to flow through the circuit. The circuit breaker then trips to shut off electricity to prevent the overload from potentially causing a fire.

Most malfunctions are because of a winding, where electrical currents pass through inside the compressor, breaking and not being able to handle its load anymore. The additional electricity ignites the oil in the compressor, causing a sudden current surge that burns out the compressor and forces the circuit breaker to trip.

Unfortunately, a burned-out compressor most likely needs to be replaced because a functional compressor is vital as it pumps refrigerant throughout your system.

Replacing the compressor can be expensive if you don't have a valid warranty. If you have a valid warranty, financing options can help. Or, you might want to look into replacing your system entirely. You can use our handy AC installation cost calculator to see if a replacement would be more cost-effective than replacing your compressor.

3. A faulty breaker

A damaged circuit breaker

Your circuit breaker may keep tripping because of an issue with the breaker itself.

To determine if the breaker is damaged, find your home's main circuit panel and look for indicators that you have a faulty breaker, such as:

• The breaker is hot when you touch it
• You can smell a burning odor near the breaker
• You see loose connecting wires
• You see burn marks on the breaker
• You see obvious worn-out parts

If you notice any of the above indicators, you're dealing with a faulty breaker that needs professional replacement. Call a technician immediately.
