But, I wanted to get an idea of what the problem might be, so I can have a somewhat informed dicussion with them. We are going to have a qualified electrician come in to look at the problem. I'm not an electrician, obviously, but to me, this seems like an improperly wired GFCI receptacle. However, when I press the 'Test' button on the GFCI receptacle, the other 5 receptacles test as correct. Here is the problem: The 3 GFCI receptacles mentioned above are on the same breaker as 5 other receptacles and all 8 receptacles are showing an open ground. When I press the 'Test' button, on the GFCI receptacle, the 2 other sticker protected receptacles go dead (like they are supposed to). A common issue with electrical outlets is reverse polarity, also known as 'hot-neutral reversed.' In thi. These other 2 are labled with a 'GFCI Protected' sticker. 01-02-22, 08:36 AM J jessstainbrook Member Thread Starter Join Date: Jan 2022 Posts: 2 Upvotes: 0 Received 0 Upvotes on 0 Posts reverse polarity but outlets and breakers wired correctly I have three bedrooms that are showing the outlets as reverse polarity but the outlets are all wired correctly. Our hall bathroom has a GFCI receptacle that protects 2 other receptacles, another bathroom receptacle and a vanity area receptacle with a sink. Reverse polarity easily can be detected using an inexpensive tool-there are models specific to 30 amp and 50 amp services. If detected, it’s best to call a certified electrician or maintenance man to fix the issue.įor products and information to help with reverse polarity or other electrical issues at your RV park or campground, contact Utility Supply Group at wife and I just purchased an apartment in the Okanagan, British Columbia (It was built in 1993). Probably a color-blind electrician (yes, they are. “If you check for it at the beginning of the season, it just helps isolate the issue quicker if it does present itself,” says Wade Elliott, president of Utility Supply Group. “If you’ve identified that the park’s wiring isn’t the problem, you’ve isolated the issue to a visiting RV.” All reverse polarity means is that someone connected the wires on one or more of your receptacles incorrectly. Looking at the featured image above, the outlet tester shows exactly this. This happens when the hot wire, also known as the black or red wire, is wired on the neutral side and the neutral wire is wired on the hot side. It’s best to check for reverse polarity at the beginning of the season before campers start arriving, so you start with a clean slate. Step 1 Plug the black lead into the middle input at the bottom of the multimeter and plug the red lead into the right input. Reverse Polarity is when a receptacle is wired backward.

In a position paper requesting the standard, the RV Industry Association (RVIA) said “In a situation of reverse polarity, power is "fed" to the neutral conductor and a short in the wiring could energize the exterior skin or other metal parts, creating a shock hazard that could cause severe burns or possibly death.”īecause of this potential safety hazard, most RV manufacturers are not waiting until 2020, however, and have already started installing reverse polarity detectors in current new models. This can be caused by improper wiring of a pedestal, or if an RV with reverse polarity plugs into a pedestal-the latter of which could cause reverse polarity on all linked pedestals-and the result could be dangerous. Simply put, it’s when the hot wire and neutral wire have been swapped. Starting with its next iteration in 2020, the NFPA 70 (National Electric Code) standard will require all newly-manufactured RVs to come equipped with a reverse polarity detector, but in the meantime, issues involving reverse polarity continue to challenge RV park owners and operators.
