What overcurrent relay could you install between phase and ground? This needs to be changed, the relay (CT) would be installed on the neutral conductor or around all phases (residual) but not between phase and ground.

Might be trivial, but residual ground fault is the addition of a Neutral ct to the existing breaker ct's, while zero sequence ground fault is the addition of a CT that encompasses all phases including the neutral.Originally Posted by Trevorvaligura
