I live in California. We just started using the 2011 NEC. Is there any requirement for a separate grounding bar at a Residential Main Service Panel if all of the holes on the neutral buss bar have not been used? This is not a subpanel. The only reason I know of for adding another ground bar is if all of the holes are used and there are not enough holes for the neutral wires to be installed separately.
