3 Phase voltage range in USA and Canada

[Bjtpower_magic]

Hi Everyone,

As we know that Single phase voltage in India and Europe is around 220V (Neglecting tolrance)
Which is nothing but equivalent to 220*1.732=380VAC (Phase to Phase)

Now talking about ranges is United states-
What i know that United states single phase supply is 120V, so Phase to phase voltage would be 120*1.732=~208VAC

What is the 3 Phase voltage in USA/Canada? how it is derived from 120VAC?

It appears to me that you have already answered your own question.
You get 120VAC single phase in USA from the 208VAC three phase.

Are you sure only 208VAC (Phase to Phase) is only getting in USA?
I have read on internet about 480VAC so wanted to clarify.

Are there 2 different supply 208VAC and 480VAC?

Of course; for 3 phase service:

Commercial 120/ 208
Industrial 277/ 480
