Electrical Safety 101: Circuit Breakers, Load Centers, and Fuses
Circuit breakers act as an automatic electrical switch, protecting an electrical circuit from damage. Overloads or short circuits normally cause this damage. A circuit breaker interrupts the current flow after a fault is detected. Circuit breakers, unlike fuses, don''t have to be replaced but instead can be reset.
