Inspector made a good call. #12 awg wire is good for 25a. in this application and 430.22 would ask for 125% of Table 430.148 which turns out to be 25a. No room to add any more load. See 430.24 The namplate on the motor will give you the actual draw of the motor once it gets running. As for HP rating of the breaker, I would be surprized if this would be a problem. Have to check with the manufacturer for that info.

How did all you get by 210.23(A)(1)?
Is the "branch circuit ampere rating" 25 because of the wire or 20 because of the receptacle? Is it a really NEMA 5-20? GFCI rated 20? Will a 20a breaker reliably start that motor?
This 1.5HP (20FLA) motor could be troubling, cord and plug connected, if it wasn't 240v.

Of course if that "1.5HP" is just "puffing" and it is really a 15-16a motor ...
...nevermind.

The branch circuit ampere rating directly correspond to the rating of the OCPD according to T210.24. So 210.23(1) is violated with a 20 amp breaker.

I know they are not common, but what about 25 amp OCPD's? or 35? or 45? I guess there are no rules for these. So the answer is to get a 25A breaker, use #12's and a 20A single receptacle with GFCI protection.

This install also requires a separate controller which could be a 25A ac only general-use snap switch. 430.83(C)(2)

and is a general-use snap switch an 'air-break switch'? If so, then you do not need a separate disconnect for the controller.--430.111

What was the question again...?
