With no 240v need or usage, and no split plugs my idea was simply to make a short 3 wire cord with a std 120v male end to plug into the inverter and then a 30a 240v female end with the ground, neutral, and single hot connected and a short little black jumper tying the two hot sides of the female cord end with the jumper right inside the cord end housing. Reversed polarity creates a potential shock hazard, but it's usually an easy repair. You cannot check for polarity with the GFCI off - there is no power to the downstream outlets with the GFCI off. I recently plugged a surge-suppressor strip into a seldom-used outlet in my base... Electrical, AC & DC. It will shock you if you touch it. A brief definition of Hot and Neutral wires: On a standard outlet, which is technically called a 'duplex receptacle', there are two wires that carry electricity. hot/ neutral becomes reversed, the supposed neutral side still remains hot resulting in the possibility for electrocution. The black is going to the narrow slot, and white wire to the wide slot. The practice is unsafe and less dangerous, however than the “reverse bootleg”, where the hot and the neutral wires get mixed up ending up on the wrong terminals with the ground terminal connected to the Hot instead of the neutral wire (Figure 7) and creating the same hazard as described in section 4.4. … On a standard outlet, there are two wires.

It’s called the hot wire and it actually carries electricity. I have 120 between wide and narrow. It's only when I press the "Test" button that tests the GFCI capability when the Hot/Neutral reversed … Inside an outlet's electrical box, the black (hot) wire should be connected to the brass-colored terminal on the outlet. DoItYourself.com®, founded in 1995, is the leading independent home improvement and repair website. Two different outlets (but on the same circuit as the one I originally asked about) test as hot and neutral reversed. Hey Guys- This was on an older house that had some of the electrical re-done. The first outlet that I wanted to inspect, that was indicating hot neutral reversed, I went ahead and pulled it out. Most things plugged into it will still work correctly with the 115V difference, but there is potential for a major shock or fire there. I do, which is how I found the reverse polarity to begin with. With it wired as described, a reading of "Hot/Neutral Reversed" on your tester is likely an indication of a loose neutral wire. Incredibly,according to the lights on the "dime-store" tester, all but 2 of 22 outlets, have the Neutral & Hot wires reversed. If you measure between hot and neutral you will see 120V (if I understand USA terminology and voltages correctly) if you swap the leads of the tester you will measure exactly the same voltage. New panels that were all romex but half the receptacles in the house had no grounds. So its a new to me problem, lol. Website operating problems contact Webmaster. There is also a wire behind the outlet that isn’t grounded. Its worth it on a 20 yr old MH, even if it dont solve the issue. The hot is always the smaller of the two slots, and the neutral is slightly longer. Visit http://thecircuitdetective.com/outlet_tester_readings.php for more resources.

Inspect your receptacle. https://www.amazon.com/Gardner-Bende.../dp/B00170KUPC. They are wired correctly, connections are good, etc. If you get this reading on an outlet tester, don't believe it. The pump would come on even when the controller was off. Reversed polarity is when the hot and neutral connections at a receptacle are wired “backwards.” Wiring is color-coded, and the black wire is “hot,” meaning that it is electrically energized, normally to about 120 volts. The bare or green wire should be connected to the green ground screw on the receptacle. ... the tester you are using is correct then I would be checking the wiring as much as I could to make sure I had them all correctly wired. It's probably loose at the previous box. Next is the single receptical, with one white and black wire in box. On this exterior GFCI, the tester showed it had a ground. Why would a wall outlet give a dim indication on a tester of hot-neutral reversed when everything appears to be wired correctly in the outlets? Electricity may still be inside a plugged-in device, causing a greater chance of electrical shock upon handling the item. Weird thing happening. If you have the black wire on the gold screw, and the white wire on the silver screw, with the bare wire on the green screw - the outlet is wired properly.

I have an off the grid cabin in Ontario Canada that currently is powered via a 240v feed off a 4000w generator. To check for reversed neutral and ground wires, measure the hot-to-neutral and hot-to-ground voltages under load. Thanks. We are trying to ease into solar and currently have a 900 w 120v inverter with plans to upgrade to a 3000 w but still 120v as it seems all 240v inverters are very expensive. Everything is wired correctly. A standard receptacle tester cannot detect a Bootleg ground reporting it as correctly wired or “correct”. Third receptical has two black and two white wires, originally reversed, and working before the short. I bought it a few months ago and I am remodeling it now. Used a voltage tester and, indeed, neutral-ground is 120v and hot-ground is 0. All rights reserved. Electronic Equipment and Computers, http://www.doityourself.com/forum/li...-pictures.html, Tester says ground and hot are reversed -- doesn't look it, Can't figure out odd wiring after pulling old duplex outlet. But when I pushed the button on the tester to trip it, the lights switched to Hot/Neutral Reverse and would not trip.
