In many cases, the power is 208v 3-phase (that's measured between any
two phases). If you look at each phase to ground you see ~110-120v.
Single phase 220v is sometimes done by using two of the three phases.
You don't get the full voltage but usually equipment doesn't care too
much.
All of the US DEC gear that uses 3-phase is the 208v 3-phase variety.
There's another version of 3-phase that doesn't allow this. I'm not
an electrician so I don't know the exact differences.
My shop is wired for 208v 3-phase and it make running things like my
2065 & RP06s *much* easier (although not easy on the wallet). :-)

I thought that main breakers in the US split-phase system were rated
for amps across the full 240V of the main feed? On Wed, 2009-01-14 at 15:19 -0500, Ethan Dicks

Um... yeah... 11kW,
not 24kW. I'm in the U.S. That and I don't have adequate electric

upgrading the pole. I've got 100A for the house and quonset hut
*combined*.
24kW should be enough for anyone ;-)
Of course, if you're in one of these funny 110V countries, that's
only
11kW in which case my electric shower will eat most of that.
