When I'm at home, I use an adapter and plug my TT into a 20 amp outlet. I've heard that you shouldn't run your A/C when only plugged into 20 amps, but the breaker for the A/C in the TT is only a 20 am...
My AC plugs into a 20 Amp plug on a 20 amp breaker in the camper. When I want to run AC at home I pick up power at the outlet near home breaker box, (on 15 amp breaker) and run the cord to the AC.
