Connecting GEC's In A Panel

Magnettica

How do you connect your grounding electrode conductors to a main service panel?

A) Romex Connector

B) Plastic Button Connector

C) E.M.T. Connector

D) No Connector At All

------------------------------

I was speaking to a local electrical inspector last night who told me that a company is making a special connector specifically for this purpose. You don't actually use a romex connector for this purpose, do you?

I put mine through the small hole in the panel.
Never had a problem before.

I have used a romex connector. Most of the time just the small hole in the panel.

He is referring to a Kenny clamp. If you go to the Mike Holt forum and search you will see recent topics on it.

While I think they look great and show good workmanship I would not want the AHJ to require them as it is not a code requirement IMO.

Kenny clamp, that's what they're called. This person mentioned the name of them I just couldn't remember it. Pretty stupid if you ask me.

Marc postes a pic of one of those, I believe on this site. They look nice, but PRICY.

I actually drill a 1/4 or so hole with my unibit right in the back corner where that liitle gap in the sem is....This keeps the ground tucked tight into the back corner and out of the way....looks neat. oh, and no connector.

Magnettica

How do you guys "getaway" (for lack of a better term) with not using a connector? I think if I just made a hole with a step-bit without a connector Mr. inspector would cite 110.12.

"Kenny Clamp"... about 4 bucks.

For me it just makes for a neater job, or more workmanlike as in 110.12.
I have never had a problem with doing it that way....Watch, just because I said something, Ill get bagged for it next week or something..

mdshunk

110.12 basically referrs you to the NECA standards book. NECA book permits running the GEC out of a small hole. Most panels have a couple of small KO's for this purpose.

Magnettica

Oh yeah... now I remember.

Looks like a plumbing fitting..

Magnettica

Workmanlike is what I was thinking.

Just splitting hairs here and making a discussion over much to do about nothing too important.

I don't see any good reason to use a $4 device when a $.10 or $.00 one would work.

mdshunk

You're correct... there is no overwhelming reason. They just look cool, is all.

Some people thing it will keep the small shower of sparks from coming off the GEC where it enters a small hole if it is ever pressed into service to earth a HV surge.

If you're using armored ground wire, you're pretty much stuck with using a fitting like the Kenny Clamp.

So 110.12 refers to NECA specifications?

Just want to give a sigh of relief that we still exist to you guys
