The Light Source | Why 277 volts for lighting? | Bulbs
Most industrial facilities get their power in a 480 277 volt 3 phase 4 wire system, because 277 is the phase to neutral voltage for 480’s phase to phase. The 480 volt wiring is generally used to power large industrial equipment, and the 277 volt wiring powers industrial scale lighting. These two voltages tend to go together because you do not need a transformer to use the 277 voltage, which ...
