RV "Hot Skin" and GFCI?
Yesterday I discovered I had the troubling “hot skin” condition. After some troubleshooting and testing of different configurations, I determined I could only resolve the hot skin condition by physica...

Ans: Because the open ground was downstream of the unit.
wa8yxm is correct, the inter wire capacitance would create a divide by 2 voltage divider as in 114V / 2 = 57 Volts.
If I accept your answer as the true situation (meaning the EMS is not faulty), I guess that would imply the presumed problems with the shore power cable were limited to hot-to-ground leakage, and that the open ground remains somewhere inside the coach. If so, I should be able to reproduce the situation by switching from shore power to inverter-supplied AC. I'll try that in a bit. However, I'm skeptical as I'm quite sure that when I disconnected the shore power over the weekend the hot skin went away even when on inverted power. Again, I'll work to confirm this.
Thanks!

Just a guess....the PI Ground is not wired to the RV Power Distribution Panel Ground.
Regarding the Inverter, the Inverter Neutral is NOT bonded to Earth Ground so it will not cause a Hot Skin to Earth voltage.
