There Are 3 Reasons Why A Circuit Breaker Keeps Tripping:

Won't Reset - Trips Immediately:

#1. It will not reset because there's a short in the wire attached to the circuit breaker.

A wiring short can occur between two live wires, between a live wire and a neutral (white) wire or between a live wire and ground.

When shorts happen, large amounts of power travel across the wire causing the breaker to instantly trip, thus eliminating the over current danger. This does not mean that you have circuit breaker problems! In fact it’s just the opposite and it’s doing its job correctly.

In these cases the circuit breaker will not reset until the shorted wiring has been fixed. Excessively trying to reset it can do additional damage to the wiring, the breaker and any device plugged into that circuit.

  • Tip: If you think a short has happened in your home ask yourself this question: “What was I doing before the circuit breaker tripped?” It can give you a clue as to where the short exists. It’s also possible that a device you just plugged in or turned on has a short and you do not have wiring or circuit breaker problems.
  • Example: If you just plugged a blender in you can try unplugging the blender and resetting the breakers that are tripped. If the breakers don’t trip again your wiring is fine and you need to buy a new blender. If however you have unplugged everything that could be causing the problem and the circuit breaker will not reset, you need to schedule an electrician to correct the wiring problem.

A shorted wire cannot be fixed by excessively trying to reset the breaker and doing this can increase the size of the repair. It could damage other appliances or components sharing the same wiring.

If you have questions regarding shorted out wires or circuit breaker problems you can call our Mesa AZ electricians for free over the phone help. They will walk you through a few simple and safe steps to try to correct the problem before scheduling an appointment to repair the problem.

Trips Frequently:

#2. It keeps tripping because the wire connected to the circuit breaker is overloaded.

As mentioned earlier, circuit breakers limit the maximum amount of electrical current that can flow across the attached wires for safety. An overloaded condition happens when this maximum safe threshold is crossed, resulting in the circuit breaker tripping off to stop the wires from overheating.

Possible solutions to correct overloaded wiring

Reduce the power demand on the wires:

Sometimes plugging an appliance or device into another circuit can eliminate this problem if your breaker is overloading because you are taking part of the demand off the overloaded circuit and applying it to a different one. Just make sure you are not overloading that circuit now.

Tip: Where numerous light fixtures are involved, changing your standard incandescent light bulbs to CFL’s or LED’s can reduce the power demand enough to correct the overloaded condition. Replacing five 65 watt lamps with five 13 watt CFL’s will reduce demand by over 2 amps or about 15% on a 15 amp circuit. LED lamps provide further reduction in energy use. Doing this will save you money on your electric bill and possibly eliminate the need for an electrician.

Stop using multiple devices at the same time:

This can be an inconvenience and it’s more of a temporary remedy than a long term solution. Everything plugged into to a circuit draws power and when it’s all used or turned on at the same time the total power demand is increased. Using appliances or devices one at a time can prevent the breaker from overloading but when you forget and run them at the same time you’ll quickly remember your circuit breaker problems.

Add another power circuit:

Providing additional new electrical circuits to supply ample power is the best solution if you cannot reduce the demand enough to solve the problem. To determine how much additional power is needed you will need to add up the wattage of everything on the problem circuit and divide it by 120 volts. This will give you the amount of total amps required.

Example: An overloaded 20 amp kitchen circuit that has a microwave drawing 1800 watts on it along with a toaster drawing 1600 watts would require 3400 watts or 29 amps (1800 +1600 =3400 total watts | 3400 watts divided by 120 volts = 28.333 amps). In this scenario one additional circuit would be recommended for using both at the same time.

If you would like help determining how much additional power you may need you can call our in-office electricians in Mesa AZ for free over the phone help. They will make the calculation for you and provide you with a free competitive estimate for a professional installation.

#3. The circuit breaker is worn out or broken.

Often time’s broken or worn-out circuit breakers will not reset in older homes. It can occur in newer home too, when the panel door has been continually left open exposing the breakers to the elements. Exterior main panels in Mesa that have a South or West exposure can experience shorter life expectancy from their breakers due to additional heat as well.

If you have a worn-out breaker in your panel that will not reset there is a possibility that you will, in the near future, need to replace other breakers too. Think about it like tires on your car, they all get about the same usage and have all aged the same amount of time. It’s not uncommon to see multiple circuit breakers shutting down at random in these cases. See our circuit breaker replacement page or contact our Mesa electricians for more information.

What is a circuit breaker and what does it do?

They are there to protect the wiring inside your home from overheating and possibly starting a fire. If you have a breaker that keeps shutting down there is definitely a reason why it’s happening and the services of a good electrician may be required.

Each circuit breaker has a maximum amount of current (amperage) that it will allow to pass through it and each wire has a limited safe amount of current that it can deliver without heating up. This relationship is a vital safeguard and properly sizing the breaker with the attached wire is essential. Never install a larger breaker to correct the problem if your breaker shuts down repeatedly or will not reset; you could start an electrical fire.
