Ampere Rating of AC Motors
Ampere ratings of motors vary somewhat, depending upon
the type of motor. The values given below are for drip-proof,
Class B insulated (T Frame) where available, 1.15 service
factor, NEMA Design B motors. These values represent an
average full load motor current which was calculated from
the motor performance data published by several motor
manufacturers. In the case of high torque squirrel cage
motors, the ampere ratings will be at least 10% greater
than the values given below.

Caution — These average ratings could be high or low for
a specific motor and therefore heater coil selection on this
basis always involves risk. For fully reliable motor protection,
select heater coils on the basis of full load current rating as
shown on the motor nameplate.
