The above is the key. If the product has wire sized for 30 A and is adequately protected internally to accept the faults available from a 30 A branch, that should be adequate to meet the needs of safety. I'm not aware of any Code based requirement claiming only loads between 16 A and 24 A can be on a 30 A circuit. If you can find one, I'd appreciate the reference. BTW, 15 A breakers are a standard size and is identified as such in my 1999 NEC, ยง240-6. The Code, on the other hand, allows any NEMA 5P device to be protected by a 20 A breaker.
