Yes. The USA switched our mains voltage from 110/220 to 120/240 about 50 years. There is a tolerance built in (10%) so that if a circuit is actually running at 100 or 220 then its within specs. A 120v circuit can run anywhere from 108 volts to 132 volts and be within spec. Its a pet peeve of mine when people say 110/220.
