Ask the manufacturer or UL if you put a 50A plug on 15A rated air
conditioner and connect it to a 50A circuit.

Have you seen air conditioners plugged into 50A circuits? I didn't
think so.

Yes, actually, I have. I did so, once. No, thinking about it, twice.
Would you like to hear the details?

I would.
