If a continuous duty motor is larger than 1HP, these requirements apply:
Nothing stops you from adding additional protection or tightening the temperature bands, if doing so makes sense from an engineering perspective and won’t cause undue interruption in operations.
Section 430.32 also provides requirements for motors of one horsepower or less [430.32(B) and (D)]. One difference in this horsepower range is you don’t apply FLC percentages. And if the motor isn’t automatically started and isn’t permanently installed, you can provide overload protection via the short-circuit and ground-fault protective device (e.g., branch circuit breaker) [430.32(D)(2)].
