I'm curious as to what NEC code you think would be cited to fail a 30 amp breaker installed on this particular unit. Continuous load is less than 24 amps.
To answer the OPs question, #10 is fine provided you aren't wiring this thing in a ridiculously hot ambient temperature and/or contending with a long run of wire.
And because it has not been mentioned, one could use a combination of fuses and Breakers as well, even mismatched ones like a 40 amp breaker and 35 amp fuses
Amen, table 430.52 allows a range of OCPD serving a motor circuit.
If the question is about code legality, you are allowed to increase the OCPD size feeding a motor circuit while keeping the conductors sized for 125% of nameplate current. If it is a question about good design practices, then you would want to dial in that OCPD as close to the nameplate load as possible.
