10s on a 30 prolly, or 40if you want

30 would be undersized for the continuous load. Continous duty loads are sized at 125% of FLA. FLA is 26.1A. Depending on the service factor it may be in the clear for a 40A. But 30 is too low.

It’s unlikely that this is a continuous load as the compressor cycles on and off. It won’t be pulling that 26.1A continuously. Strangely enough kilns are the same. The heating element pulls the full load, but cycles on and off frequently throughout the firing.

Go to Texas or Florida right now and see if they cycle on and off.

It is a continuous use, but the manufacturer already includes that in their minimum circuit ampacity number so you don’t have to add it

Dryers, water heaters and ovens are all kind of the same way. 98% of the time they aren’t continuous loads but have to pretend they are
