Thanks for the 'help' wiseguys,
I shot an e-mail to square-d, tech support says that is the intent of the KO, I'm waiting to see if there is a document stating such. I'll let you know.
In the meantime I have a special tool to keep the inspector happy, can you guess what it is?

A bottle of Liquor? :wink:

FWIW, I scoured a lot of SqDs technical drawings, and none of them even showed those holes, let alone specified what they were for.

I have found them in some of their PDF's and DWG drawings, they identify them only as a ".44 Dia KO"

I'm gonna go out on a limb here and say they are part of the manufacturing process, and NOT intended for a GEC.

I don't think so, some (not all) are made to be punched out, they are not just holes and as Iwire said, some meter enclosures are made the same way and list these for the GEC.

Yeah, punched out for a connector... :grin: Bwahhhh.

I see nothing in that section that requires that bonding to be accomplished by a cable fitting.

Me either but I do see where it says it shall be made electrically continuous by bonding each end of the enclosure to the grounding electrode conductor and where bonding shall apply at each to all boxes, and enclosures.

If the GEC is bonded in the middle of an enclosure and then passes through the enclosure at another location without being bonded at that point I certainly see where it would not be in compliance with the letter of the code.

Who was it that said that only what was written in the code could be enforced? ;)

I would think so

E) Enclosures for Grounding Electrode Conductors. Ferrous metal enclosures for grounding electrode conductors shall be electrically continuous from the point of attachment to cabinets or equipment to the grounding electrode and shall be securely fastened to the ground clamp or fitting. Nonferrous metal enclosures shall not be required to be electrically continuous. Ferrous metal enclosures that are not physically continuous from cabinets or equipment to the grounding electrode shall be made electrically continuous by bonding each end of the raceway or enclosure to the grounding electrode conductor. Bonding shall apply at each end and to all intervening ferrous raceways, boxes, and enclosures between the cabinets or equipment and the grounding electrode.

I don't see where that says the bonding needs to be at the point the GEC enters the enclosure. Only that each ferrous metal enclosure needs to be bonded. If you use PVC as a race way for the GEC it isn't getting bonded until it hits the ground bar/lug. So how would a "kerny clamp'' or any other clamp change the effective nature of this?

OK Mike, you buy the Kenny clamp, I will save my money for better things. :cool:

how much does a kenny clamp cost?

About $8.00 if I remember correctly. Not worth it as far as I'm concerned. If you have the GEC properly secured before it enters the cabinet then the small KO's are the right port to use.

FWIW, I always use a romex connector to secure the GEC to the cabinet.

I used to do that also until many inspectors here decided that the RX connector wasn't approved for use to secure a #4 or #6 THHN wire not to mention that using a 1/2" RX connector for the GEC eats up another KO in the top of the panel that you may need (especially when doing an upgrade).

Are you still using the 2002 or earlier edition of the NEC?

Look at 250.64(E) of the '05 and '08 and see if you don' t see the words boxes and enclosures

Hey,
Does anyone know of any documentation that would show an inspector that the tiny KO in the bottom of a panelboard/load center is intended for conveniently entering the enclosure with a GEC , let's say a bare 6AWG?

You must have done too good of a job if your inspector is looking that hard to find something he can defect your work for. I just have to ask... if you did use that hole in the enclosure for your GEC how does this make the install un-safe?

Some inspectors aren't happy until they find something. I know who those folks are in my area, and 'salt the job' with minor infractions.... a j-box cover missing, or not having the panel schedule on the panel door yet. Something, anything (no matter how trivial) they can find that would be an super-easy fix on my part. They're content they've saved the world, and I get closer to gettin' paid.....
 
kenny clamp/ breathe hole

kenny clamp/ breathe hole

Kenny camp...thats where inspectors meet to come up with this waist of time!:grin: Stick you prefer a "romex" clamp because you are a "romex" type of guy!:grin: I always thought that the little whole in the bottom of the can was a "breathe" whole for electrons!:roll:

No, it's the 'weep hole', so any excess electrons can be 'arranged to drain'.... Where do you think static electricty comes from? :grin:
