Ground Clips?

[The Iceman]

I have seen these Green Ground Clips for years but have never used them. I don't see any UL listing on them. The ones I am referring to come from NSi, cataloge #GGC-1000. They are for #10-14 copper. Are they listed to use for bonding equipment grounding conductors to metal enclosures? I would say no, 2008, 250.70, 250.8 A.

Why would they not comply with 250.8(A), just because they are crap? The last resort?

Exibit 250.3 from the 08 NECHB.

The " : " was staying in your link.

Every once in a while the grounding clips come in handy, say for grounding an old box without a tapped hole for the ground screw.

:-?

I do not read it that way:

Where a 10-32 grounding hole is not already drilled and tapped in a box, a listed grounding clip may be used.

...those clips are garbage though.

I have plenty of 6-in-1 taps that all broke at the 10/32 mark

I wonder why?

Me neither. If the box doesn't have a hole you may use one or if the box does have a hole you may also use one.

It has to do with mad skills

Oh, you have those too?

Sure...I'm full of it!

Agree, I always have them on me just for this reason. Unless of course the customer wants to add changing a box as an extra.

these from greenlee are great

If the back of box is tight to a brick wall/steel beam or some other item you would rather not deal with:

...and it's not even broken.....yet

Yes they are, and by some sheer coincidence, the 10-32 is the one I've used the most by far. One thing you should be sure of is that the drill tip punches through what you're drilling before the threading teeth start grabbing.

That matters because, when I get a box without a dimple for the green screw, and I'm molunting it to sheet metal, I mount the box, then drill and tap the hole, so the threads match.

That's what's known as a bottoming tap. I've recommended them here, too. Their main use is for threading closer to the bottom of a blind hole.

I loose or break to many of those high dollar tools. A tek screw for drilling the hole followed by a hardened ground screw with self forming threads is the way to go.

Thanks for the information. I agree with chris, they are crap. I have never used them and probably never will.
