If you're running 3 #6 THHN to feed a house panel, you can phase tape the ungrounded conductors. However, the grounded conductor must be pulled in white, gray, or other manner that complies with 200.6(A). I know that is the code, I just don't know why. This came up because we did a 6 unit bldg. and one of my newer guys didn't realize it and phase taped the #6 neutrals. When we reviewed it he asked WHY the code doesn't allow phase taping the neutral and frankly I couldn't come up with a good answer. Anybody know the reason that the code doesn't allow phase taping the neutrals smaller than #4?
Also, in searching for the answer to this question I noticed several posts that said for ungrounded conductors you can phase tape any size. We are not allowed to phase tape wire smaller than #8 here in SF (nless part of a cable). I've done it that way or so long I thought it was part of the NEC but I couldn't find a reference.
