Industrial Hot-Skin Shock…
Anything connected to AC power can develop a hot-chassis voltage and should be properly grounded!
Everyone,
Here’s a reminder Hot-Skin shocks don’t only happen on RVs. They can also occur on home appliances such as refrigerators, as well as industrial machinery. But in those cases we call them a contact voltage or step voltage rather than a hot-skin voltage.

Never accept feeling a shock!
While it was commonplace to feel shocks and tingles from ungrounded appliances back in the ‘40s and ‘50s, all modern wiring should be grounded and most of it GFCI protected.
So if your refrigerator or toaster oven or your guitar amplifier shocks you, then something is wrong with the grounding and it should be repaired immediately.
Many years ago the aluminum siding on my parents house had a hot skin. I discovered it when I was home from college helping my dad do yard work and I leaned up against the siding near the meter. The meter was mounted on wood and the service cable had rubbed through the outer insulation and a small area of one of the hot legs!
