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 ...

After the source was converted to 480 V, the same buck-boost transformer could be turned around and used to convert 480 V to 600 V for the remaining equipment until it could be converted to the 480 V level. At the conclusion of the conversion, the standard 480 to 120 V transformer could be used for lighting use.

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.
