I had this in the Grounding vs. Bonding forum. I wondered if moving to the NEC forum made more sense. Sorry if you have already read it.
Does a metallic weatherproof cover need a direct contact to ground even if the gasket on the backside of the cover may protect the cover from energized conductors?
NEC550.15(D) and NEC406.5(B) seem to be very clear. However, a manufacturer has released a flat weatherproof receptacle cover to the market where the mounting screws go through plastic inserts and make no contact with the metal parts of the cover.
Any information on this matter is most appreciated.
Thanks,
DM
