gascircuit breakers leak check for testing

2021-3-17All circuit breakers provide "overcurrent protection." This means that, if current in excess of the breaker's rating in amps is flowing through the circuit, the breaker will trip and disconnect the circuit to avoid overheating the wiring or equipment it serves, which could potentially start a fire.
