A circuit breaker box houses the main and individual circuits for appliances in your home. Circuits serve to protect the home in the case of current overload. If an overload of power occurs, because of faulty electrical wiring or a multitude of other reasons, the breaker will trip causing power to be shut off, either to individual appliances or to the entire house.
Most homeowners have experienced a tripped circuit breaker at one time or another. If you are unable to get power to a particular appliance, chances are the breaker was tripped. Because this is common, especially in older homes, it is important to label each circuit in the circuit breaker panel. To label the circuits, you can check by switching off each circuit to determine what power source each is linked to. Labeling each circuit in the circuit breaker box can make it much easier and less frustrating in the future.
