Power comes from the circuit breaker panel. It controls electricity flow in your home. Switching it off stops electricity to the outlet and switch combo.
Locate Your Circuit Breaker Panel
Find the main breaker box in your house. It is usually in the basement, garage, or utility room. Look for a metal box on the wall with a door.
Identify The Correct Breaker
Inside the panel, breakers have labels. Find the one that controls the room with the switch and outlet combo. The label might say “kitchen,” “living room,” or “outlet.”
Switch Off The Breaker
Flip the breaker to the off position. You should hear a click. This action stops electricity from reaching the switch and outlet.
Double-check Power Is Off
Use a voltage tester or plug in a lamp to confirm no power flows. Test both the switch and outlet to be sure. Safety first, always.
