I feel like an idiot for having to ask this question that I should know. Residential 200A service, concrete foundation, a piece of rebar is stubbed out to make the UFER ground connection. I would need to run #4 copper per table 250.66 correct? Also will your normal "acorn" or ground rod connector work to connect the wire to the rebar? I'm pretty sure code still requires two ground rods 6' apart, but do you really need it if you have a UFER ground?
