How To Open Breaker Box

A breaker box, also known as an electrical panel, is a metal enclosure that houses circuit breakers. Circuit breakers are electrical switches that protect electrical circuits from damage caused by overcurrent. When an electrical circuit draws too much current, the circuit breaker will trip, which will stop the flow of electricity to that circuit. This can help to prevent electrical fires and other damage.

To open a breaker box, you will need a flat-head screwdriver or a breaker box key. First, locate the breaker box in your home. It is usually located in a basement, garage, or utility room. Once you have found the breaker box, open the door using the flat-head screwdriver or breaker box key.

Inside the breaker box, you will see a number of circuit breakers. Each circuit breaker is labeled with the circuit that it protects. To turn off a circuit, simply flip the corresponding circuit breaker to the “off” position. To turn a circuit back on, flip the corresponding circuit breaker to the “on” position.
