The present USA voltage standard range is 120/240VAC 60Hz at +-5%, and has been for many years. There are exceptions to this in large buildings, where polyphase systems are sometimes used, but standard single phase residential and light commercial is all 120/240 service. We haven't had 110/220 for well over 60 years.
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.
