Electrical Current flowing through door

I have an electrical issue that has me completely confounded? There is an electrical current flowing through my Rig that can be felt at the entrance door. What makes this problem more confusing to me is that this is the second time it has happened at the same park with two different vehicles.

Two years ago we were camping at Arrowhead Provincial Park in our Sunset Trail TT. We were plugged in at the post, it was raining that weekend and you could clearly feel AC current at the door. At times there was enough current to be verging on painful and at other times it was nothing more then an annoying buzz. The post is far enough away that we were using 75 feet of 30 amp cable and I always use a surge protector plugged in at the post.

Today a friend has my 2015 Greyhawk at Arrowhead. It rained yesterday , he is plugged into the post, has 100 feet of 30 amp and the surge protector in place. All plug connections are elevated to keep them off the wet ground. He is again able to feel AC current at the door of the trailer. He dried and inspected all of the plug connections and the problem continued. Finally he switched to a different receptical on the post and problem ended.

I am totally confounded as to what the problem is here, but having had it happen at the same park on two different vehicles tells me it is their problem? Does anyone have any idea what the issue would be and what can I do to ensure it does not impact my RV?

Bad grounds/neutrals some place. We had that issue many, many years ago at a Rally. It turned out that there were some bad spots in the wiring, the facility had to shut down all the power for the day and replace some of the feed cables.

Also very dangerous. Avoid that pedestal until it is fixed. You may be able to do some testing with a VOM to identify the problem but the cg should be the one to tear into it.

I'm thinking the neutral on the recepticle at the post has a bad connection.

Thanks guys... I am only moderatly conversant in electrical work... So this question is for my education only... How does the faulty neutral at the post translate into a current flowing through my rig?

YOU become the return/neutral. This problem could potentially be deadly. Be careful out there!

Neutral and ground are, electrically, the same reference point. Your trailer contact with ground, though metal water etc. has, at least partially become the path of least resistance. As others have said, dangerous.

What the previous posters said. The ground completes the circuit instead of the neutral, everything in the trailer is grounded and becomes the circuit. If the trailer is hot, it can be grounded by you touching the trailer and a ground outside of the trailer. A short circuit through you, not a good thing.

Had the same issue at Pismo Beach, Calif. Happened when I connected the RV's propane hose from my BBQ to the RV propane connection !

A bit scary. Fortunately, I didn't turn on the propane !! and disconnected and proceeded to use my 3 gal tank I brought along. Haven't had that problem since.

Dealership lack of knowledge

Thanks All!

The amazing part of this discussion is when this happened in my TT I assumed that the problem was with my trailer. When I called the dealership and spoke to their service department, they never even suggested the possibility that the problem might be with the parks wiring. They took my rig in to the shop and kept it for the winter where the supposedly "Fixed the problem"... I never trusted that place and this seems to be one more reason to prove my distrust... And one more reason to be happy with the purchase of my new Rig from a much more reputable dealer!!!
