I have a ground loop around a small rectangular building, ground rods at four corners of the loop. Lightning protection provided on roof. Presently, the down conductors from the air terminals connect to the ground loop, and the ground bus in the panel connects to this same ground loop. NEC and NFPA says
that the lightning ground system and the power ground system need to be seperate systems, but connected together.But, if these two systems need to be bonded together anyway, why can they not be the same system (why can't I have one grounding system that both the power grounding and the lightning protection tie in to)?because i blv bonding makes them one system i.e parallel paths to earth
