Hope everyone is doing well. I had a question about setting the ground fault protection for a 500 hp motor that is being protected by a 1000 amp breaker at 480V. The breaker has LSIG setting capabilities and I wanted to coordinate the ground fault setting on this 1000 amp breaker with the 4000 amp main breaker that also has ground fault protection. I just wanted to know, should I be careful not to set the ground fault too low on the 1000 amp breaker that feeds the 500 hp motor? I want to coordinate it with the main, but am afraid that I will be dealing with nuisance tripping if I set the ground fault protection too low.
