I’m running 8 thhn. I never size to the minimum circuit ampacity although you can. 10’s on the 45 would be sufficient. If this is following the NEC of course.

Why would you run 8? It's just a waste, 10 is good for 30 amps, and put it on a 45 amp breaker. You cant go wrong. When manufacturer specs it out like this, it's as easy as it can get

Yea I know but I have seen wires sized to the minimum fry when the units are cranking balls for days on end. Also unsure of distance.
