Quick Panel Question

[cbass]

I inspected a house the other day that had every ground wire entering the panel "pigtailed and under a single lug on the bus bar. I wrote it up to be further evaluated by an electrician. I had never seen all the grounds under a single lug before. I guess my question is this. Do you guys write up when grounds and neutrals share a lug in the main panel? Do you guys write up when multiple grounds only or multiple neutrals share a single lug on the bus bar in a main panel? thanks

Sometimes you can read terminal details on a sticker in the panel enclosure or door. Usually you can gang up to two of the same size.

Yes I have seen grounds ganged into little bundles and always call it out.

I was on an inspection this weekend, the buyer was an electrician. When I opened the panel there were 8 or 9 bundled branch circuit grounds at the same lug and 3-4 grounds spliced with a wire nut inside the panel and under the same lug. He was all over that s--t. Installed in 1976 but who cares, there's a reason that you don't do these things anymore. As far as in know it's 2 grnds per lug 1 neutral per lug and no mixing grnds and neuts. I always call out bundled grnds, g & n at same lug or multi neuts at same lug. The apparent reason for the seperate g & n is that the n can energize the g if there are connected., so I'm told.

2011 electrical code is out as this buyer also informed me, lots of new stuff.

Gotta read the label of course. Yesterdays panel allowed 3, which I see often based on memory.

[Chad Fabry]

Almost all allow three grounds per terminal- many allow four

[ericwlewis]

when you say bundled, are you referring to when about 10 grounds are twisted together to form a "stranded" looking wire?

[allseason]

Yes, 10 or more together, all under the same lug.

[cbass]

yea, thats what I saw as well.
