Well, I got home and plugged my EMS directly into the wall plug to test it and got the Reverse Polarity code as expected. I turned off the circuit breaker, removed the plug receptacle and reversed the wires. Voila! It works properly. This puppy has had reverse polarity since it was installed by a reputable electrical company! I’m glad that I hadn’t damaged any electronics in the RV. Thanks again for all of your help with, tool suggestions, pictures, etc. It made it easy for me to tackle this myself. Not bad for a somewhat mechanically inclined 66 year old woman! Most of you assumed that I was a man but at the end of the day, it doesn’t make any difference as we are all very capable of many things!??

It could be worse.. When they put in central air at my old sticks and bricks

The kid hooked the black wire to the green screw. (Hot to ground)


Home is where I park it.

Sounds like a good outcome!

Reverse polarity on an outlet won't harm electronics because it doesn't change the sort of power the device "sees"; it's no different than plugging in an (unpolarized) plug flipped the other way over. Reverse polarity is problematic from a safety standpoint mainly because the hot line is the only one switched by a circuit breaker, so a tripped or shut off breaker doesn't cut off the power if the two are reversed. The normal current path is still broken, of course, so it still protects against a normal overload, but a short circuit to ground would not trip the circuit breaker where the polarity is reversed. If the fault current is sufficient, it would trip the circuit breaker in the house's electric panel where the polarity is correct.

More common is connecting 240 volts and the fun starts immediately.
