You're all correct. The 3000/33 (or 44 or 48 or 58 or IIILC) runs on:

       208v SINGLE PHASE - in the US a single 208v (rms) phase is
provided
                           by connecting between 2 phases of a 208v 3
PHASE
                           panel - i.e. adding "2" 208v phases that are
                           separated by 120 degrees gives a single 208v
                           sinusoid - NOT TWO PHASES - typical
industrial
                           power

  OR   240v SINGLE PHASE - in the US a single 240v (rms) phase is
provided
                           by connecting between "2" 120v phases that
are
                           separated by 180 degrees - typical house
power
