Yes, 120 degrees with any standard type of transformer.

I has to be 120? to achieve 208/120 or 480/277 volts.

Off topic slightly but this thread jogged my memory- There is an old thread about phase angles, 240V vs. 208V. In it there is a post by Infinity, I think, that mentions something about "...grabbing 208V and stretching them out so they become 240V".

Can someone post a link to it. I have tried searching for it and had no luck.
