('08 Code)
I have a roof top DC system to an inverter with ground-fault protection connecting the 480v interactive system by a breaker in MDP.
Am I correct in reading 690.47 that my equipment grounding conductors will satisfy the grounding and no grounding electrode (other that the existing AC service) is required ??
