Home Wiring 101: Dealing with Circuit Breakers and Fuses
By: Barbara Johnson
How to Turn Power On and Off to a Circuit
Each circuit should be labeled next to the breakers or fuses or on the inside of the service panel door to indicate which breaker or fuse controls the wiring to each part of your home.
If the circuits aren’t labeled, you’ll have to the flip the breakers or unscrew the fuses one by one until you find the one that controls the circuit you want to turn on or off.
To turn the power off to an electrical circuit, flip the breaker switch toward the outside of the panel or unscrew the fuse. To turn power to a circuit back on, push the circuit breaker switch toward the center of the box or screw the fuse back in.
