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...
I turn off the breakers for the microwave and electric water heater, so they don't get accidentally used. My extension cord is short and 10 gauge. Works fine.
