It was on the house outlet that I plug my trailer into, they installed A 50 amp outlet but they used just a standard 14/2 wire for me to plug into so they are the hot and neutral and then the ground wire so that only made it a 30 amp service with a 50 amp plug. I don’t know what they were thinking but I’ll have to look at his trailer and see why he did that but I needed a true 50 amp Service since I have two ACs refrigerator a washer dryer and all the other stuff and I couldn’t figure out why my second I see the bathroom plugs in an outside plug wasn’t working and my girlfriend kept telling me she smelled electrical and I couldn’t find anything or smell anything and I just happened to check the plug and pull it apart
