I understand how the 120/240 delta works, but what's the high leg on 480?

I know they have 480 delta transformers, and 480 wye transformers. If there calling it delta, it must have a high leg correct? And using the pythagorean theorem like the example above I came up with 415.7v That can't be right though.

Here is one more thread to read..

Thanks, Harry. I'll take a look at it. Mind you, I'm only a 2nd year apprentice just wanting to learn, so maybe be asking a few dumb ?'s.:laughing:

Nothing dumb about your questions , I'm just a 39th year apprentice what the hell do I know..:blink::laughing:

I'm not to sharp on 480 Delta , I don't believe I've run into it before except at school a looooooong time ago, but that's why we're here so we can all learn together..:thumbsup:
