When ever I plug the extention cord into the trailer it will blow the outside reset button or will blow the circut breaker. The only thing in the trailer is an airconditioner and one plug in outlet. Turned off the two switches in the electrical box in the trailer and replugged the trailer back in and still blew the circut. Am wondering if there is a possibilty of the box being bad or maybe a screw in the electrical wiring somewhere as I do have cupboards in.
Thank-you,

Try plugging the cord only. If the CB trips, you know the problem is in the cord. If the cord is okay, then the problem is in the trailer between the cord and the "switch box"

if you have an ohm-meter or know someone that owns one, plug your trailer and the extension cord in and check for a short, without plugging it in to the power source and just start backtracking from there.....good luck

Are you saying it pops the GFI circuit?
Most GFI's don't like the longer extension cords. Especially the cheap cords folks buy at Home Depot and Lowes.
Try plugging your cord into a circuit that is NOT GFI protected.
Try using a shorter cord. ie a 50' cord vs a 100' cord
Try using a better quality cord of heavier guage wire.
Modern homes typically use 20amp circuit breakers for Wet rooms. (Kitchens and baths) and 15 amp circuit breakers for the other rooms of the house. Your A/C in the trailer may be pulling more than 15amps. See if you can plug into a circuit that is on a 20 amp breaker. Most shore power connections are based on 30 amp circuits. So a 30 amp breaker would be even better, But these are not very common in typical homes.
