Is the 1/4" Knock-out hole in the bottom of some 3-R panels and discos an additional "weep" hole (they already have two, one in each corner...) or are they intended for use for the GEC to pass through?

If not, what type of connectors are listed for #6 and #4 bare copper solid soft drawn wire? The NM connectors I buy are only listed for 2 14-2-Gs to 1 10-2-G NM or UF Cables.

I have a feeling I've been doing this wrong for a long time...

I have always used the 1/4 knockout fot the #6 ground wire. Was tought that that is why it's there. Never had any inspector say anythig about it. Have worked in 5 different states and at least 15 different cities.

We use a 1/2" ko, and a MNC conn. Other than that a 1/2" ko, emt/pvc, etc.
Never used the 1/4 hole.

What's the hole for?

Nothing in the Disco Instructions pertaining to it...

Thanks, John... (looking forward to the mail)

<dumb question>
What's an MNC connector?

Crap, won't get to put the "100% Code Compliant" sticker on the service I did today...

Virgil,

Are you talking about a hole or a 1/4" KO? If you have to punch it out how can it be there for drainage (or 'weep')?

This first pic shows the weephole to the left, and the 1/4" KO to the center.

This second pic shows the weephole on the right.

So, what's it for?

Man, I didn't notice before how crooked the washers were...

I always thought they were there to be used. They are also in the Bottom and Top of every indoor-rated panelboard that I've ever seen. I've always used them for the GECs.

I thought they were for the flanges (the bolts that hold them on, rather) that fit over the big holes for weather heads. I dunno its always been a guess.

A regional practice in parts of NorCal is the use of 8-, 6- or 4-AWG galvanized/armored bare copper with a 3/8-inch "two screw" connector, and a ground clamp that independently secures/bonds the armor and copper conductor. I believe this has evolved from details in utility-accepted service-entrance requirements.
