Do you have an automatic transfer switch in your unit?
Do you have an inverter or power converter in your unit?
Is the outside plug an automatic fault type plug, one that stops current flow if there is a short?
The wife and I were talking about this very same thing, working out of a campground. We are full timers and workampers. A,t the campground where we are at right now, I have already fixed a fifth-wheelers water problem and a small electric problem for a pop-up.
I'am not a certified tech. only did this to help out fellow campers and accepted no monies in return for services.
I plan to get the schooling and start my own business. As we travel to workamping assignments , someone is always in need of repair at parks.

The company IOTA did have a replacement for this system---it costs $104.99.
I contacted Thor motorhomes who bought out Damon and the fellow said they don't use the system I had? When I asked the fellow if he had heard anything about those units, he was very evasive and only said they (Thor) was not aware of problems.
These people (RV Industry) certainly talk to each other, after all most of the other manufactures have requested their customers to bring in their units so they may exchange the item(s) in question.
To me this is a very dangerious situation.....If the manufacturer is aware there are possible fire problems with their products and/or the RV Industry is aware then why is there no recall or an attempt being made to alert people of this hazard....
THER HAVE ALREADY BEEN FIRES and LOSS OF PROPERTY, THANK GOD NO DEATHS OR INJURYS.

We are full-timers and workampers currently in Alpine TX. We had a situation where our power blinked for a few seconds, and our air conditioners wouldn't kick back on. I immediatly shut down the entire electrical system and turned off both of the air units, tv's and everything else we had on. While at the master switch panel I could hear something snapping about every 30 seconds, comming from behind the master panel. I removed a few drawers to get a good look, and my heart skipped a few beats when I saw the IOTA ITS-50R automatic switch box sparking and snappping. the box was so hot I couldn't touch it to remove the cover. I went outside and disconnected the 50 amp power cord from the campground pedistel. Thank God we were home and not on the job at the campground.
We contacted the IOTA company and they stated they no longer make this model switch (too many problems).
If you have one of these units-----don't trust it, they fail under heavy loads when the climate is hot, such as both airs on and the refer. running....
Good luck, and be safe,
