Well...after reading that article, I now have two more gadgets to pack in my handy camping tool bag (both of which I already own but never thought to bring along).

Just an observation. Looks like the ground point was not burnished (is still painted) and also appears that there is a star washer between terminal lug and ground point (a no-no). For proper bonding there should be no hardware between any stacked terminal lugs and bottom lug at bonding point. Additionally, the area beneath lugs should be burnished to expose bare metal and the J-BOX should also be correctly bonded.

Wow. It "looks" fine from the picture. I wouldn't have guessed.

What is the "J-Box"? "Junction Box"?

Just checked all circuits for reverse polarity and all outlets checked "Correct."

Sorry for that. Yes junction box. But really meant that if the bonding for ground returns is not directly to the primary return item used (framing, etc.) but rather through any other means (box, tab, etc.) that bare metal to metal contact between the other means and primary return item should still be accomplished. "Floating Grounds" may cause great havoc with electrical circuits.

Very interesting thread.
I read an article recently where a little boy was killed by the "hot skin" condition. His dad plugged into the pedestal and the boy touch the door handle to go inside and was electrocuted. I started researching and came across the same No shock Zone website as linked in this thread. It's a very informative read and provides a simple inexpensive solution to mitigate the risk.
I also use a Frank's auto transformer and originally wondered if it offered protection from hot skin. After reading of Herks experience, it sounds like the answer might be maybe. Regardless I purchased a non-contact tester and it officially became a part of my set up routine this past weekend. Is it probable that this will happen? Who knows? But it absolutely is possible. I figured for 20 bucks and 20 seconds it's worth it to reduce any potential hazard. The alternative sucks.

Start with the article in Big Baron's post and then go to the ground/Neutral lugs from the converter.

One or the other should fix it.

The Franks will alert you to reverse polarity with the red light (Much like every other power monitor - Surge Guard, etc).

However, if the failure is on the "output" side (like a poorly bonded Neutral at the camper's frame), the power monitor will never "see" it.
