An other way to test this is to. reduce the 30 AMMP trailer plug to 15 AMP power cord and plug it into a wall plug at home.
If it pops the breaker it is the trailer.
then find the trailer's breaker box, and trip all breakers and pug it in again. see what happens. Nothing?
then reset one breaker at a time until you know which will trip the house breaker.
If the trailer doesn't trip the 30 amp breaker at home, I doubt it is the trailer.
only if the house circuit is on a GFI. and in most houses GFI is on outside circuits, bathroom circuits, and kitchen circuits. a garage circuit usually is not on a GFI, so make sure you plug into a GFI Circuit.
