120/208V three-phase wye is the standard low-voltage commercial distribution in mid-size buildings — retail, mid-rise office, and many institutional sites. Generator selection at 208V trades higher full-load amps (compared to 480V) for elimination of step-down transformers and direct compatibility with 120V plug loads.
