Where can a GC-200 Ground Fault Relay be used?

GC-200 Ground Fault Relays work in conjunction with new Square D bolted pressure switches, or circuit breaker shunt trip coils installed in service entrance switchboards. GC-200 relays replace existing Square D GC-100 relays. They may also be used with competitor breakers and switches with 120Vac shunt trips.
