All our single-phase 220V motors will operate on either a 208V or 240V nominal power supply, which are the most common types available in North America after you move up in voltage size from 110V (or 120V).
- The "nominal" voltage is simply a standardized number used by the power company to differentiate the type of voltage supplied to your building.
- The actual voltage at your building will typically be +/-5% of the nominal voltage.
- Also, motor factories must ensure that motors will operate on +/-10% of the voltage marked on the motor label.
- That means a motor marked for 220V will operate on an actual voltage between 198V and 242V.
