Roof Fan Grounding
Roof Fan Grounding
(OP)
I just walked our building roof and noticed tat some fans have external grounds and some don't. Just wondering what common practice is. NEC doesn't address it except in 430.12 where it implies that it may sometimes be required. I would think it's safer just to do it as I have a ground loop around the perimeter of the building.
