What are the requirements regarding gounding and bonding should I consider when installing conduit and cabling from 1600 amp enclosed circuit breaker to bus bars of existing switchboard? The cable is 5 sets of 4-500Kcmil and 1-4/0 copper. I need to know if I need to drive ground rods and/or go the main waterpipe etc. Or is the 4/0 to switchbr. grounding bus the only grounding situtation to take care of?
