[johnp4191]

When we plug the camper in it trips the site GFCI at Interstate park minnesota. Found two breakers in the camper the when shutoff GFCI Is fine. However we shut everything off unplug everything and turn the breakers back on it trips the GFCI again. Anyone have similiar problems and found a solution?

We tried to plug into the adjacent site and had the same problem, however, the camper on the opposite side had the same problem as well. The odd thing is my amp probe is measuring enough to trip the GFCI even when everthing is off.

We had a similar problem and it turned out that the junction box under the slide on the frame of the trailer had some water in it. The box was not sealed well and driving in slush and heavy rain forced the moisture into the box. Just take the cover off and if water runs out you have solved your problem. Ours is sealed now.

On ours, the outside receptacle is also on the GFCI circuit. You might check that one.

Also, under the slides is a junction box. You might pop the cover on those and make sure all is well.

We have decided the water heater element is shorting out. Once we switched to gas the problem went away. -Tested it this morning and it tripped the GFCI right away. We are on our way home now so this evening I will post my findings.
