I disagree.
 
Re: Gounding Screw

Scott, :D

Anyway, I would only agree that there would be a problem if it were a flat head screw.

But wierdly, (cool word :cool: ) the code doesn't address that. :confused:

I don't see what's confusing about what the screw on the bottom of the box with an EGC on it is.

If I didn't have a green screw with me I sure wouldn't be coming back tommorow with one when I have this silver one here right now.

Now 5 or 6 people standing around this box with the silver screw for twenty minutes................. :)

That is assuming that there was a problem to begin with. :p

Re: Gounding Screw

For the record, I do use the UL listed green screws ( ;) ) only because they don't protrude so far out of the back of a 4" square. But for old work boxes, octagons and other places where there is clearance behind the box, the clamp screws will do just fine. :cool: But when in doubt I bring a can of green paint with me just in case. :roll:

You do?

Are they PL listed? (Peter's Laboratories) :D

There are no 'listed' grounding screws on the market.
 
Re: Gounding Screw

I know, did you see the winking dude? I just had to make light of this ridiculous notion of "UL listed" screws. :D

Just making sure, I did not want any lurkers to think that UL listed grounding screws where available.

On the outside or inside?

Under what type of lighting conditions?

See we can muddy up even a multiple choice question. :D
 
Re: Gounding Screw

My hair color is now grey,but I had a blonde moment. I want to repeat that I was referring to a oval head screw that would provide a better connection not a flat head screw. I still think that a screw designed to hold a box clamp does not have the surface equal to a grounding screw.

The truth is it is designed to hold a clamp not for grounding. The NEC does not prohibit it from being used for used for grounding and I accept it. However the NEC may have had a blonde moment when it was allowed. romeo
