How to Reset a Circuit Breaker

Before you head to reset your circuit breaker, turn off all light switches and unplug, turn off or disconnect important appliances and devices in the area of your home that has lost power. This will prevent damage when the power is reset. Don’t forget to save any files before disconnecting your computer. 

1. Find the circuit breaker box

It's usually located wherever power enters the home — try the basement, garage or utility closet. If this outage has left you in the dark, be sure to grab a flashlight before you go searching for the box.

2. Open the cover

Open the circuit breaker box, but never touch the box with wet hands or remove the cover. You’ll be able to identify the tripped breaker in one of a few ways. Look for a switch that is not in the on position. In fact, this switch could be anywhere in between the on and off positions. Some circuit breakers will have a bit of orange or a red next to them to indicate they’ve been tripped. If any part of the box feels hot, do not flip the switch. Leave it alone and call an electrician.

3. Reset the circuit breaker

When you reset the breaker, use one hand and stand to the side to avoid electrical arcing in case the breaker malfunctions. First, flip the breaker to the off position. This might seem counterintuitive, but the switch has to be turned off before it can be turned on again. You should hear a click as the switch flips into place. Then flip it from off to the on position. Again, you should hear a distinct click as it snaps into place.

Finally, head back inside the house and make sure the power is back on.

Troubleshooting Circuit Breaker Problems

If this step-by-step guide for resetting circuit breakers has not solved your problem and your power has not returned, go back to the breaker box and flip the switch off and then on again one more time. If the power still doesn’t come back on or if the breaker shuts off again, there could be a number of things tripping the circuit breaker. You may have a short or some other issue that needs to be addressed by a professional electrician.
