Updated video on 3-light tester failure!

My video demonstration of a Hot-Ground causing a 3-light tester to falsely indicate Reversed Hot-Neutral Polarity…

Here’s my updated video demonstrating how a 3-light outlet tester indicating a reversed Hot-Neutral polarity can also be caused by an external Hot-Ground in a campground.

I posted an article back in November on why this false polarity reversal indication is an important concept for troubleshooting apparently random RV hot-skin voltages in campgrounds. Read it HERE.

Don’t confuse cause and effect

So an outlet with reversed Hot/Neutral Polarity wiring doesn’t cause an RV hot-skin voltage, an external Hot-Ground Voltage causes a 3-light tester to incorrectly indicate a Reversed Hot-Neutral Polarity.

Watch my updated video

This explains a lot of the confusion about the causes of Hot-Skin Voltage.

Let’s play safe out there… Mike
