Three Phase Four Wire Wye. The most common commercial building electric service in North America is 120/208 volt wye, which is used to power 120 volt plug loads, lighting, and smaller HVAC systems.In larger facilities the voltage is 277/480 volt and used to power single phase 277 volt lighting and larger HVAC loads.sed primarily in industrial facilities to provide power for three-phase motor loads, and in utility power distribution applications. Nominal service voltages of 240, 400, 480, 600, and higher are typical.
