Q

Voltage, Nominal. A nominal value assigned to a circuit or system for
the purpose of conveniently designating its voltage class (e.g.,120/240
volts, 480Y/277 volts, 600 volts). The actual voltage at which a circuit
operates can vary from the nominal within a range that permits
satisfactory operation of equipment.
