I am going to bring 400 amp service to a remote location, meter only no disco's till they terminate at their locations one to the house the second to the shop; The house has a ufer to establish service, however the shop doesn't have a ufer. Would I be required to establish its service at the remote location and bring 4 wires to the shop or can I still establish service at the shop and use 2 ground rods in lieu of ufer? Thanks sparky
