Siemens 30-amp 1-Pole GFCI Circuit Breaker

Siemens ground fault equipment protection circuit breakers provide protection to equipment from damaging line-to-ground fault currents. This circuit breaker will detect line-to-ground faults and de-energize the circuit for all ungrounded conductors of the circuit. If the current going to the equipment is greater than 30 mA than the current coming back the GFCI will open the circuit stopping the flow of electricity.
