panelboard calculations...

Winnie, the angles are 60 degrees, but that does not change the fact that the line voltages, properly defined, are 120 degrees apart.

I never said that they were not. I was trying to describe where those weird 'off by 30 degree' phase angles come from in a balanced three phase system. I submit that Smart$'s diagram in post #38 makes the point far more clearly than my wording.

Winnie, I was emphasizing that point because other members have given convoluted explanations explaining the 60 deg angles in their incomplete phasor diagrams (no arrow heads).

Yes, a picture is worth a lot of words.
