connecting multiple neutrals toghether best way?
I have to add romex to a 3 gang box wich already has 5 neutral wires tied in. I need to tie the 6th neutral wire in, the other 5 are under one wire nut. Is it better to break up the bunch and tie in 3 and 3 and pigtail the groups of 3 together or just slam the 6th one in the same cluster?

Neither, at least don't slam it in.
Try to twist the new neutral as cleanly as possible to the others. Get you a big blue wire nut and twist away.

HAHA, slam was a relative term. I'll group it in. The problem was, most of the existing wires in there aren't stripped nearly enough to make a good connection in such a large grouping, but also the electrician/homeowner seems to have thought that the code for wire length in an electrical box was 6mm - so I can't really strip to much more back to make a better connection. I'll be sure its good though. thanks.

you mean there is code staying length of expose wire inside the device box? I didn't know that... I thought as long as I don't expose bare part of the wire from the pigtails...etc that would be good enough... I cut some time quite long bare part of the wire some time quite short... as long as it make good connection....

I am fairly sure the code states that sheathing into a box must be a min of 1/4" and no more than one inch. Conductors must be at minimum 6" and able to extend at least 3" from the box. I don't remember an exact code on bare length, but Common practice is 3/4" for screw terminals and there's usually a wire stripping guide on the back of back-connecting switches and recepticles. However, with stripping, I think a common sense approach would be just simply make sure you strip enough for good contact without leaving uneccessarily exposed wires.

If there is one thing that makes me crazy it's finding 2" of wire inside a box. It's the most annoying, avoidable inconvienence ever.
