rexlion, notice that Terry succeeded in running the a/c at ohm. Resistance is futile.
And Terry, I am glad that worked out for you. The first time I tried running the trailer a/c at home, the circuit breaker in the house blew. I upgraded the circuit. Then I tried again and the extension cord got very hot. I upgraded from an ordinary extension cord to a heavy duty cord.
That worked just fine.
Moral of the story: my guess is that you know more about electricity than I do. But to anyone reading this who is not an expert, it is a good idea to check that your home circuit is up to the task and that you have a sufficiently beefy extension cord.
