How do you connect ground fault protection system to a circuit breaker?
If I have a 480 circuit breaker and I want to protect the system from ground fault (i.e. install ground fault protection to this circuit breaker)
How the connection for this circuit will be ??
CT, relay, 480/120 transformer and the main circuit breaker and its shunt trip
How they are going to be connected to each other
connect the EFR between CT and OCR relay star points. The setting of EFR is usually 20% of OCR setting.Connect trip contacts to trip circuit or bus
