I would like some opinions on whether the grding clip on a self grding duplex receptacle will satisfy the requirements of metal box bonding in 250.148(C).
Installation is emt with a copper egc spliced within a recessed metal outlet box.
The debate is whether or not the grding clip along with the receptacle supporting screws is "equipment listed for grounding, or a listed grounding device" as stated in 250.148(C). If so, no bonding pigtail would be required.
I have always installed a "pigtail" to bond the box, but I also see validity in the other side's argument. It would be nice to settle this without the "what if the receptacle is removed", although I don't know if that's possible.
I might be asking for a little much here, but technical "proof" would be nice if someone has it. I have searched and come up short.
Anyway, thanks in advance.
