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.
North American Voltage Ranges. In the United States and Canada, the electrical power supplied to most homes is from a split-phase system. That power enters your home at about 240 volts, that voltage is split at the main circuit breaker panel into two 120 volt halves. Those 120 volt halves are routed through the home to outlets.This 120 volt level is commonly referred to as 110, 115, 120, or 125 volts.
