Reverse Polarity and GFCI Trip 2002 Affinity
Thanks to members here and some other forums I was able to find out why I was tripping a GFCI breaker at my storage building and getting the dreaded "Reverse Polarity" while using stepped down 15 amp shore power at other locations. I'm sharing this so that other RVers can save a lot of time.
While it is possible to have reverse polarity on a 15 amp by having the neutral and hot on the wrong sides of the receptacle, that wasn't my problem. It also could have been the even worse "Reverse Polarity Bootleg Ground Outlet" which could have electrified the whole coach with deadly results. Fortunately, I didn't have either of those problems.
The advice I followed was remove the white neutral wire one by one for each 120 volt circuit to nail down which circuit was the problem. I decided to start with the water heater circuit and boom, that happened to be the problem circuit. It turns out that the electric side of my water heater has some kind of short or ground problem with the element that resulted in tripping any GFCI or getting the male voice "Reverse Polarity" error while using 15 amp shore power.
For now, what I did was remove the white neutral wire from the circuit breaker and taped the end. Next will be replacing the element. I am going to invest in circuit testers anyway to avoid problems at campgrounds and any other place I plug into.
