The rating at motor terminals is identified by which term?

• A. Line Voltage
• B. Nameplate Voltage
• C. Rated Voltage
• D. Phase Voltage

Answer: (B)

The voltage printed on a motor’s nameplate is the voltage the windings are designed to operate at. This is the official rating you use to choose a power supply and wiring, and it applies to how the motor should be connected and powered. That is why the correct term is nameplate voltage—the label on the motor itself identifies the exact voltage it is rated for (including dual-voltage configurations, if applicable).

Line voltage refers to the actual supply you have in the building, which may or may not match the motor’s rating, and phase voltage is a concept used specifically in three-phase systems describing voltage between lines or to neutral. While “rated voltage” might seem synonymous, the standard, unambiguous term shown on the motor and used in documentation is nameplate voltage.
