panel spec question

**Jim Robinson** · 04-12-2010, 01:57 PM

Today I was reading the specs on an ITE panel from 1985. On the ground bar, it stated "Copper - One # 14 - # 4 AWG and two or three # 14 - #10 AWG."

So, I think that what they mean is the main lug can hold a wire from # 14 up to a # 4, and the terminal screws can take up to 3 wires if they are between #14 and # 10. Is that what others think that this means?

Those things always confuse me. Often, there's a chart that shows where certain wires can be placed (larger or smaller screw slots), but I can't read the "labal" in your picture.
I just hope that the "labaler" can wire a house better than he can spell.

That means:

one #14 to one #4 copper
one, two or three #14 copper
one, two or three #12 copper
one, two or three #10 copper

"one, two or three #14 copper
one, two or three #12 copper
one, two or three #10 copper"

Does that also mean any combonation of these?

I see it now. For all of the holes on the ground bar, if there is only one wire, it can be up to a # 4. If more than one, it must be no larger than a # 10, and there can be up to three of a # 10 - # 14 in each hole. I wouldn't have put the word "and" in there, if that is what they meant. To me it reads that you can have a #4 wire, and three more # 10 wires, but not one more # 10, since it only says "and two or three...", not "one, two or three".
