How many EGC under one screw?

[gwilcox (Gerald C. Wilcox)]

Is there a limit? Or can you like the picture shows, stuff as many as you can get in…Cutler Hammer 100 amp panel.

[bhamilton (Bobby Hamilton, CMI)]

The panel will tell you how many and of what size can go underneath one of the screws. Just looking at the pic, I would say there are too many.

Usually no more than 3.

“The product standard(UL 67-Clause 17.2.6) allows multiple equipment grounding conductors, but not more than 3 No.10 AWG or smaller in a single opening in a wire terminal.”

I will call it if there is more then one.

Ron, I believe you are referring to neutrals. 3 grounds can be placed under one screw.

[Mark_Thorman]

I would call out the black wire also.

This is not always the case for grounding wires. The label would really need to be checked for the quantity and size ranges acceptable.

Neutrals, 1 wire per hole.
