Stephen, If you still have the old corroded block heater I would love to have it for my NoShockZone experiments. Please contact me directly at -- email address removed -- to arrange shipping.

Gary, Yes, test the pedestal first using a NCVT for proper polarity and a non-hot ground before plugging in. Ideally, you'll also us a voltmeter to check the voltage. Then test your RV for hot-skin voltage after plugging in. If your RV has a hot-skin voltage, you'll detect it from inches or...

Yes, but you'll need to check voltage between the chassis/body of the truck and a known-good ground connection. A short ground rod (18 inches of copper pipe or rebar) in the wet ground would be sufficient for this test. Anything more than 2 or 3 volts AC above earth ground is suspicious. One...

I'm Mike Sokol, the author of the NoShockZone.org electrical safety articles linked to here about how GFCI's work. Very interesting thread... I'm currently running an experiment determining if hot-water heater elements with a pin-hole leak from corrosion will produce Hydrogen-Oxygen gas from...
