Fluorescent and other discharge lighting can be used at 277 volts. 480 volt single phase, 480V three phase, and 277 volt single phase loads can be used on this system. Also good for minimizing voltage drops on long runs. Disadvantages are that a step down transformer is required to get 120/208 or 120/240 volt power for lights and outlets.
