Sorry for the late follow-up.....

Your Code book collection is impressive, and your information great!

Not that great I'm afraid, as I have precisely two NEC code books, the 2002 thanks to the generosity of an ECN member and the 1971 thanks to eBay.

Paul, how'd you think to look for this in Article 200? I wouldn't have found it there, that's for sure!

I think I was just looking up "Delta" in the index:

Delta-Connected,4-wire, 3-Phase Supply, Identifying high leg, 200-6(c).

Yes, that's when it was added. '68 prescribes "tagging or other effective means."

Ah, so that's got the orange pinned down. Haven't we had threads in the past in which it's been said that in the 50s/60s some areas commonly used red for the high leg?

Quote
Paul, I think you are referring to 210-5(c). There is no 210-15 in the '71 NEC.

Oops, yes, that was a slip. [Linked Image] I meant 210-5(c).

By the way your right, Paul is very helpful.

May I quote you on that? [Linked Image]
