How man current carrying conductors w/ Common Neutral?
#1

Ok this is way the heck off the beaten path of DIY but here it goes.
My father was testing me to see if I could find out how many current carrying conductors you could use with a common neutral.
Now we looked as best we could through the 2005 NEC and just could not find it. Could someone help me locate it in the 2005 NEC I also have the 1996 NEC code handbook as well.
Thanks in advance.

Just so you know, a neutral, or properly a "grounded conductor", IS a current carrying conductor.
This is not an answer you will find in the NEC.
Very basically; for a single phase service you can have two line conductors for a neutral.
For three phase you can have three.
Was there more to the question than this?

actually that was it.
From what he told me it was part of his Journeman test way back in 1980 as he recalls.
I didn't know if it would have been article 215.4 or not.
Thanks for the reply.

Just remember that the different hots need to be from different phases to share a neutral without overloading it. This usually happens automatically, from a 2 or 3-pole breaker, but just keep it in mind.
