Never Seen This Before.....

[480sparky]

Working on an existing home and had to take one of the ancient brown receptacles out. As soon as I removed the cover, I though,"Oh, crap. This is gonna be a mess..... The installer wrapped the ground wire around the mounting screw!"








Nope! The device was MADE this way!!






New one on me!

Pretty cool!:thumbsup:

Self grounding receptacle for a metal box?

Looks like a Circle F auto ground.

What's the big deal. If you noticed most of the new Leviton decora switches, GFCI and AFCI have a similar selfgrounder.

I don't use Leviton.

I don't use Leviton.

Oh well , No selfgrounding for you!

Very familiar with them. Those and similar ones have been around for decades.
It's interesting how somethings are more common in different areas of the country.

Never Seen This Before.....

I'm old and have never seen one before either. Curious though, it doesn't appear to connect to the Ground Screw Terminal.
Could this be a device to hold the Mounting Screw in place; now done with a cheap piece of Plastic?

I've seen self-grounding receps before, but never shaped like this.... and made of copper.

The green EGC screw is threaded into the metal of the Yoke. . . and, although you can't see it openly, the male cord cap equipment grounding tine contacts to the metal of the Yoke.

All auto ground clips "hold the Mounting Screw in place" and, in addition, are tested and evaluated as part of the effective ground-fault current path from the yoke to the clip to the yoke mounting screw to the box.

That was my only thought, not sure why it would even be considered for grounding, is there one for the top mounting screw?

that is pretty neat.

I do have to say that the receptacle is far from ancient though, I mean, geez, it even has a ground screw.

So you never seen one of these. I think eagle used the wire or was that pass Seymor.

No, but I really only deal with industrial applications and the minor fixes I do around the house, 99% of my boxes are plastic so it would only serve as a screw retainer

Hubble recepts that have USB in them also have self ground wire on the yoke. but if the wire has egc it has to be on the green screw for resi use.

Yes, you would have to use the EGC in the cable if you have a nonmetallic box. But if the box were metallic you would only have to connect the box to the EGC when using a self grounding receptacle.

my AHJ wanted egc tied to yoke even in metal boxes.
