Sometimes 120 volts is referred to as 110 volts or 115 volts and 240 volts as 220 volts or 230 volts. As a central vacuum manufacturer we use the 120 and 240 volt motors, not the 110 or 220 volt ones. The 120 and 240 motors will not be adversely affected if used with lower voltages.The 120 volt motor will be fine on a 110 volts. And a 240 volt motor will be fine on 220 or 230 volts. But not the other way around. A 220 volt motor would be damaged if used for long periods of time on a 240 volt circuit.And the same for a 110 volt motor running on 120 volts.s a central vacuum manufacturer we use the 120 and 240 volt motors, not the 110 or 220 volt ones.
