2 grounds under one screw in my panel?


Is it allowed? I am talking about equipment grounds, NOT grounded (neutral) wires. If it matters, it's a Cutler-Hammer CH 100-amp panel.

Thanks.

This is fine. Some even allow three grounding conductors of the same size.

Yes, the CH bar is listed for 2 grounding conductors. Check the label inside the panel for sizes and numbers.

No, legally it depends on the code and the listing of the panel.

If the panel is listed to accept two grounding conductors of the same size an inspector CANNOT prohibit you from doing it, unless of course there is a local code amendment prohibiting it.

But if one is a 14- and one is 12-awg....not allowed? Didn't know that. Guess I'll have to fix it.
