430.52 (C) (1) Exception No. 2 would likely permit it.
The manufacturers installation instructions may specify a 15 Amp branch circuit, I have run into this with Bathroom vent fans and installing them on a 20A Bathroom circuit.
Overload relay elements for very small full load motor currents could in theory have such a high resistance that a bolted fault
at the controller load terminals produces a short-circuit current of less than 20 amperes, regardless of the available current at the line terminals. So then in 110.10 would come into play.
