I was not doubting 3 phase... I was asking about the voltage. I have never heard of 480V even though I had to work on 3 phase equipment in the military (it ran at 440V).
So I decided to look it up and much like 120V here in the US and it appears like, 440, 460 and 480V are used pretty interchangeably.
