Receptacle metal faceplate grounding

[Maybe]

the code says you have to ground metal faceplates. I have a handy box with a metal faceplate I was told the faceplate mounting screw was not allowed by code as a grounding means?

I would read 250.146(a) and (b)

1-Who told you that?

2-And if that statement were true how on earth would you bond the metal faceplate?

Start at 314.25(A). Then go to 250.110.

Anybody have any problems with the practice of using a metal blank plate (handy box blank) on a plastic wall box? Or a metal octagon blank on a plastic ceiling box? (assume exposed work for both)

Yes, a few times inspectors asked if we would change the blank plate to plastic since the wall box was plastic..

Based on what? Would you say that plate was likely to be energized?

I don't know, they seem to feel a switch plate is likely to become energized.

well first you would tape the wirenuts and sides of the receptacle to minimize the chance of the plate becoming energized. an AFCI would be a good idea too. Then cadweld a lug to the faceplate and run a #8 solid copper and cadweld it onto the GEC.

I just drill and tap a foot lug to the back side of the plate...:grin:

Exception No. 1 to 517.13(A) alludes to the fact that the screw holding the cover to the receptacle is sufficient, assuming the receptacle is properly connected to an EGC.

I would not allow it, based on 250.4(A)(3).
