The function of the circuit breaker on the distribution box
A circuit breaker is an electrical safety device designed to protect an from damage caused by current in excess of that which the equipment can safely carry (). Its basic function is to interrupt current flow to protect equipment and to prevent. Unlike a, which interrupts once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. North American distribution boards are generally housed in enclosures, with the positioned in two columns operable from the front. Some panelboards are provided with a door covering the breaker switch handles, but all are constructed with a dead front; that is to say the front of the enclosure (whether it has a door or not) prevents the operator of the circuit breakers from contacting live electrical parts within. carry the current from incoming line (hot) conductors to the breakers.
