more than two grounding conductors in box

[stjohnbarleycorn]

Is there a code requirement that does not allow, bringing in you EGC under the grounding screw and then to wirenut the other EGC's? I don't do it because of the possibility the wire breaking from the grounding screw. I do see it though. thanks.

The only potential violation I can see would be of 300.14.

as long as the ground wire is 6 inches long it still meets the 300.4 requirements.

i sort of like the idea of looping around the ground screw and then splicing onto the ground wire for the next connection. you can still take the ground off the device without interrupting the bonding to the rest of the chain.

thanks for the quick response, I have found on numerous occasions when I pulled the receptacle out the wire at the screw broke off, due to poor workmanship no doubt. I guess it is just force of habit now.

What I will do is gather the EGCs, add a really long EGC, screwed in the middle to the box, nut that entire group up and stuff them into the box,....come trim out time, it's a lot easier shoving one EGC back in than a whole bunch (especially with lighting fixtures).
If a device or fixture needs to get dropped, continuity is not compromised.


Point is: As long as 310.4 is meet, there is more than one to skin a cat

Wherever the EGC is screwed down, there is potential for it to break...it's up to the installer to use the right amount of force.

Which reminds me....

A few weeks ago we were trimming out a bar's UC recept.s...
I said to the helper "Watch you don't break that screw" ....
Five minutes later he says "How'd you know it was gonna break?"...
"It's called 'experience' son "
LOL

For 12 and 14 wire I like the green wire nuts with the hole in them. Quick and easy. One of my instructors years back said looping around a screw and continuing was wrong because half the wire went in the wrong direction. I haven't seen where that is actually a code violation, but I don't do it. I've seen it done many times though, with all three wires.
