Ok I have a question about a high leg delta transformer. I know that phases A and C to neutral you get 120 and that phase B to neutral you get 208. I also know that between any two phases you get 240. My question is why don't you get 328 volts from phase B to either phase A or C? I believe it has to do with the was the sine waves are off from each other but am not totally sure. Does any one have a good explaination? Or maybe a diagram of the sine waves?

I disagree with you. The wording that you quoted refers to the way it is identified not the color to be used. "...shall be durably and permanently marked by an outer finish that is orange in color or by other effective means..." The "...or by other effective means is saying that the insulation covering does not have to be orange in color it can be re-identified as orange in color (if allowed by other sections of the code) but it shall be orange in color.Or be identified by other effective means.(See 110.15)

Duly noted. I suppose it is up to the way the AHJ interprets it.
