How to Reset a Circuit Breaker

Located inside or outside of your home is a circuit breaker panel (sometimes called a fuse box) that contains circuit breakers for each of the circuits in your home. Some homes have more than one circuit breaker panel, there may be a main panel plus one or more sub panels in other locations.

Caution: Please read our safety information before attempting any testing or repairs.

A circuit breaker provides protection for each of your electrical circuits by stopping the flow of current if an overload or fault occurs. When an electrical fault occurs or the load on your circuit becomes too great, the breaker on that circuit trips and interrupts the flow of current to that circuit. A tripped circuit breaker is still sometimes referred to as a "blown fuse" in reference to the older technology that circuit breakers replaced. If your home uses an actual fuse and not a circuit breaker, click here for information on fuse boxes.

Instructions To Reset a Circuit Breaker

Before electricity can be restored, the circuit breaker must be reset. However, even before you do that, you must take steps to ensure that it is safe to do so. Turn off or unplug all of the devices that are plugged into the circuit. Make certain no dangerous condition exists before restoring power.
