Yes! It worked great for about 2 1/2 days...then started shutting off periodically. The A/C is a 15000 BTU. The only other things on the trailer are
4 overhead florescent lights, about 5 110 receptacles, two porch lights, a 5 gallon water heater (that we only turn on when necessary) and a water pump. The 30-Amp side ran everything and barely put a strain on the generator
The three prong 30-amp adaptor worked perfect, so we thought that all was good. But then the generator started acting up....it would run for a while and then the generator would still be running, but it would not output any power. we thought it might be a circuit board or something, so we took it in for warranty work. The generator tech said that there was nothing wrong with the gen, and that we had the wrong adaptor. So charged us $100 for his labor to look at it, and $60 for the new adaptor. We came home and hooked up the trailer with the new adaptor, and the A/C wouldn't even come on, or it would come on for about 2 minutes, then the generator would shut down.
