Three-phase power and other 480 V loads are connected directly to the system at 480 V, and gaseous discharge lighting is connected phase-to-neutral at 277 V. Small dry-type transformers rated 480-208Y/ 120 V are used to provide 120 V, single-phase, for convenience outlets, and 208 V, single- phase and three-phase, for small tools and other ...

120/240 single phase. 120/208 3 phase. 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 ...
