Reidentifying conductors ??

[Erby]

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?

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.

Not a friend of mine, a friend of the buyer.

But I also "like" your authoritative response.

According to NEC, the wite conductor within a cable is used for ungrounded conductor if permanently reidentified. But the identificaion must a color other tahn white green or gray
