Volts Voltage is an electrical force whose basic unit is the Volt. Volts fields allow a range of low to high to accommodate a facility that has a transformer enabling the power to be stepped up or down. Typical voltages for commercial services are 120/208 (for lights) or 277/480 (for machinery). Both require a Three Phase (see definition for Phase) service as opposed to a Single Phase service that is residential or small commercial.]]>
