When you say Standard Outlet I assume you mean a standar household 3 prong outlet. If so that can be either 15 or 20 amps. In either case that is not enough to run the AC in your trailer unless you take these precautions. Turn off the frig, and the converter. Even doing this it will not work if the receptacle is a 15 amp one and may not work if it is 20 amps and has anything else on that circuit outside the trailer.
