Inside a metal electrical box, can I use multiple ground clips (one for each conductor), or is it required that all ground conductors be twisted together and pigtailed into the same clip?

I can't speak for code, but technically, the results would be the same. – DA01 Oct 5 '12 at 20:45
@DA01 yes, I know the results would be the same :D In fact, just wrapping the ground conductors against the box's wire clamps would have the same results... I'm asking about what's correct – Matthew Oct 5 '12 at 20:47
"I'm asking about what's correct" = but that's making the assumption that code is always 'correct'. ;) – DA01 Oct 5 '12 at 20:48
Fair enough! :-) – Matthew Oct 5 '12 at 20:49
@DA01 if your goal is to pass inspection and/or avoid legal problems, then that's a pretty good assumption. – derobert Oct 12 '12 at 18:04

If you are carrying ground from one cable to the next, you should pigtail them. The ground clips are there to ground the box, not carry the ground to another cable; if one were to become disconnected, you would lose the ground in the circuit.

I prefer a screw connection in metal boxes over a ground clip.

Oh, and instead of a pigtail, you can use one of the green wire nuts with a hole in the center; that lets you pigtail with a bit less effort.

I have been attaching the line ground to the screw and the load ground to the clip. I'll check out green wire nuts – Matthew Oct 6 '12 at 4:45
