BONDING

[jaydagner]

A non-metallic 4x4 box with a metal p-ring attached, is the p-ring required to be bonded?

NM Cable is the wire type.

Re: BONDING

My gut instinct tells me yes. However, a code rule to back up my answer escapes me at the moment.

Nonetheless, I never see it done.

If we can ground a switch in a metal box with the device screws, I don't see any hazard in the reverse to ground a plaster ring.

But, the code is code and we must follow it no matter what we think is OK.

Re: BONDING

does it have a way to bond it?

you are talking about the plaster rings that extend above a handy box - right?

I am not sure you are allowed to install them on a plastic box.

Re: BONDING

Good point Bob. I hadn't even thought of that.

I have seen metal rings that don't even cover the opening of the plastic box.

I think your only code compliant solution is to use a plastic ring.

I'm at least thinking "Yukkk".

I agree with Bob. And don't they have to be identified for use or listed or something? I've never seen a plastic box with a screw pattern for a ring.

This is 4 square or 4 11?
