  • What happens when you press the TEST button on a circuit

    Jul 12, 2018All 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. Breakers with a small colored button marked “TEST”—it could be white, yellow, green, or
