You are correct, but plugging in a TT into a home receptacle generally won't produce a low voltage problem, since most houses don't have really long electrical runs. The heavy gauge cable to the TT should not cause any significant voltage drop as long as you don't add extensions. Even so, I would normally only use a circuit wired with #12 wire on a 20 amp breaker at my house.
It would be prudent to check the voltage in the TT before starting the TT at any outlet, then starting the A/C and seeing if the voltage drops more than just a few volts.
At campgrounds, I always check the polarity, grounding and voltage before my TT gets plugged in. I also turn off the breaker in the electrical post before connecting or disconnecting my TT.
