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...
Also, a true 20A receptacle has one slot turned 90 degrees or is a combo of parallel and perpendicular. Otherwise, it’s really just a 15A receptacle.
