I'm working on an estate with a main house and two outbuildings. The meter is on one of the outbuildings, with lugs for the runs to the house and both outbuildings. There are no disconnects at the meter. The main house has a 200-amp panel with a main disconnect and driven rods. There are 4 wires between the meter and the 200-amp service (3) 200-amp, and (1) 3 or 4 ga., which is labelled white, but is likely the ground wire.
Anyway, I hope this is clear enough. The grounds and neutrals are all terminated in this 200-amp panel. My question is...should they be divided at this point or bonded?
