V. Marking

422.60 Nameplate.

(A) Nameplate Marking. Each electrical appliance shall be provided with a nameplate giving the identifying name and the rating in volts and amperes, or in volts and watts. If the appliance is to be used on a specific frequency or frequencies, it shall be so marked.

Where motor overload protection external to the appliance is required, the appliance shall be so marked.
FPN: See 422.11 for overcurrent protection requirements.

(B) To Be Visible. Marking shall be located so as to be visible or easily accessible after installation.

422.62 Appliances Consisting of Motors and Other

Loads.

(A) Nameplate Horsepower Markings. Where a motor- operated appliance nameplate includes a horsepower rating, that rating shall not be less than the horsepower rating on the motor nameplate. Where an appliance consists of multiple motors, or one or more motors and other loads, the nameplate value shall not be less than the equivalent horsepower of the combined loads, calculated in accordance with 430.110(C)(1).

other load(s) shall specify the minimum supply circuit
conductor ampacity and the maximum rating of the
circuit overcurrent protective device. This requirement
shall not apply to an appliance with a nameplate in
compliance with 422.60 where both the minimum
supply circuit conductor
