Have a house with 400 amp service that comes in to an attached shop. We are coming out of the milbank to two separate 200 Amp panels on each end of the house ( They are about 125' away) and another 200 amp panel in the shop.
The house is using basalt FRP rebar in the footings... So the question comes should I have scrap the FRP rebar in just the shop and have #4 rebar installed in the footings of the shop only and tie to it for a Ufer ground or should I just install the 20' of #4 bare copper in the footing along side the FRP rebar? Would one provide a better ground over the other?
