phil's outlet question

If you use a "self grounding" receptacle and it makes metal to metal contact with the box, it's grounded, if not use a grounding conductor from the box to the receptacle

thanks RBM. How do you know if it self grounding?

The self grounding receptacles have a flat metal piece that binds against the mounting screw (s)

It'll say so on the box, and usually if it is self grounding there will be a metal tab retaining one of the box screws to the frame of the recep.

That is what I did here, and the test meter is happy. Coiling the ground wire under the cable clamp in the box is how we did it for 40 years. I understand (from threads on here) that it doesn't meet code any more, and they wanna see that pigtail. But I didn't want to disturb that 40 YO romex to add self-grounding receptacles to grounded metal boxes (to replace the 2-holers), and there really isn't much inspection in this township, so I said the hell with it.
