277/480 3 phase. The 120/240 configuration is obtained from the low-side of a HV/240 volt transformer, where HV is the rated voltage on the high voltage side, and the 240 is the rated voltage on the low voltage side. Then a center tap is connected to the low voltage winding and grounded along with the low side of the primary winding.
