Erby Posted August 11, 2016 Report Share Posted August 11, 2016 So, in conversation with a primarily commercial electrician friend of the buyer, he said that it is not allowed to reidentify ungrounded conductors smaller than #6 AWG. This was after I pointed out some white hots in the panel below. Haven't heard of that but have seen numerous reidentified whites in residentisal panels around here. Your thoughts?

Douglas Hansen Posted August 12, 2016 Report Share Posted August 12, 2016 With cable systems you can re-identify white wires to be used as ungrounded (hot) conductors. Aside from panels, this happens all the time with switch legs. With conduit systems you must pull the correct color if it is #6 or smaller. Black conductors #4 or larger in conduit can be taped at their ends to show that they are neutrals. Since your friend is primarily a commercial electrician, he doesn't use cable systems and it isn't surprising for him to be unfamiliar with these rules. They can be found in 200.6 and 200.7 of the NEC. Quote Link to comment Share on other sites More sharing options...

Erby Posted August 12, 2016 Author Report Share Posted August 12, 2016 Not a friend of mine, a friend of the buyer. But I also "like" your authoritative response. Quote Link to comment Share on other sites More sharing options...

But the identificaion must a color other tahn white green or gray Quote Link to comment Share on other sites More sharing options...
