ECN Forum Forums General Topics of the Trade General Discussion Area tieing grounds together

Recently had a discussion about the need to tie all equipment ground wires together in the same box. I seem to remember a thread about this, but I could not find it.

Do all EGCs in 1 box need to be tied together?

What if you have different circuits (IE: a #12 circuit and a #14) in the same box?

Question was concerning residental, with NM boxes, and NM cable.

Thanks
