ECN Forum Forums Code Related Discussion NEC & other Code issues Neutrals Combined in Outlet Box Question

Back to basics:
Hot Neutral in Romex or in Conduit. Or Two hots & neutral
in Romex or conduit,or three phase wye 3 hots & neutal . All fine if using single, two pole , breakers as per code.
Now if you run to seperate romexs say to a J box each with there own neutrals I'd say you can't use either neutral for either circuit. One thats in each romex must be used with that romex. Otherwise you could pick up neutrals wherever.
I've seen j boxes where Electricans have just tied all the neutrals in the j box underneat one wirenut saying well they all come from the same panel.

I didn't want to get into this, but grabbing or combining neutrals can result in a shock hazzard to an unsuspecting person. Yes there are NEC Articles as quoted within this thread which I agree with. Also, '08 requires the MVBC's to be 'bundled' in the panel for neutral ID. Just a bad situation.

This thing sounds like the sort of thing done to "get 'er done", to not spend lots of billable hours that a homeowner isn't gonna want to pay for, and to not look like the electrician was gouging the homeowner, but still look like he fixed the problem. "What, ten hours at $X an hour to find and fix a loose screw on an outlet?!". And if a subsequent problem arises from this bad fix, the electrician could claim that "I didn't do it" and someone else was messing around before or after he was there. This is a shoddy way to do business, I'd agree.
