The sentence in the manual is "If installing for maximum power, use minimum 6 AWG, 90° C-rated copper wire for conductors.I’ve been reading the Gen3 wall manual and they spec out 90c rated wire.
NOTE: Upsize conductors if necessary."
I don't understand why it mentions 90C rated wire, I'm not aware of any technical justification for it. But I'd be inclined to think that is referring to the temperature of the insulation, not of the overall wiring method. So 4/2 NM or 6-6-6 SEU would be OK.
