Furthermore what is hot ground.
What does hot neutral reverse mean. The hot neutral reverse is a state of wires in an outlet when the hot wire replaces the neutral wire and the neutral wire interchanges its place with the hot wire. If your outlets polarity is reversed it means that the neutral wire is connected to where the hot wire is supposed to be. There is always electricity flowing out of an outlet with reversed polarity even if an appliance is supposed to be off.
What is live neutral reverse. This means that the outlet is wired backward. It is a pret.
A common problem I see during home inspections is called Reverse Polarity or Hot Neutral Reverse. The Neutral of your service is connected to Earth ground at the service panel. This should be the only point the ground comes in contact with the neutral.
The vast majority of items or appliances it is of no consequence but it usually means that any single pole switch will be in the neutral line so there will be a live or hot that will go unswitched. XOX - Hotground reversed - Line and ground wires are terminated on eachothers screws. XXO - HotNeutral reversed - Line and neutral connections are switched with eachother.
Because ground is not involved the problem may be in another box. Insidious because devices will still work and average people will not know anything is wrong. The correct way would be to figure out why they are reversed.
Are they spliced wrong somewhere. D Daniel Holzman Civil Engineer Joined Mar 10 2009 5832 Posts 4 Apr 21 2012 Hot neutral reverse typically occurs when the hot wire it is supposed to be black is attached to the neutral screw on the outlet. 2 No reading between the hot and the neutral but 120V between the hot and ground and 120V between the neutral and ground indicates an open neutral.
3 No continuity between the neutral and ground - Check for tripped GFCI device first 4 If all the branch circuit breaker are on you have a bad connection on the hot or neutral wires. The usual cause is a bad connection. Missing neutral would cause the receptacles and lights to not work but still activate a proximity voltage detector.
My experience when a plug-in receptacle tester indicates Hot-Grd Reverse that the problem has always been no neutral. If your outlets polarity is reversed it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing but it is.
There is always electricity flowing out of an outlet with reversed polarity even. GFCI Show HotNeutral Reverse. This was on an older house that had some of the electrical re-done.
New panels that were all romex but half the receptacles in the house had no grounds. On this exterior GFCI the tester showed it had a ground. Note just because the black and white wires at the receptacle are connected correctly to the receptacle that does not mean somewhere upstream the wiring is not crossedreversed.
Only way to know if the polarity is correct is to check it with a tester. Here are a couple Links on the dangers of hotneutral reversal at the wall receptacle outlet. What is hot ground reverse.
Hotground reversal often means a missing neutral. Missing neutral would cause the receptacles and lights to not work but still activate a proximity voltage detector. Click to see full answer.
Furthermore what is hot ground. The black wire is the hot wire which provides a 120 VAC current source. With it wired as described a reading of HotNeutral Reversed on your tester is likely an indication of a loose neutral wire.
Its probably loose at the previous box. If it comes from an upstream outlet that is where I would check for a loose white wire. If its in a splice make sure none of the wires in the splice are loose or broken.
You must measure neutral-to-ground or hot-to-ground voltage. If the neutral-to-ground is 120V and the hot-to-ground is a few volts or less then the hot and neutral wires are reversed Fig. Also What does a hot ground reversed mean.
Hotground reversal often means a missing neutral. The only effect of a hotneutral reversal would be that it would try to detect a grounded hot instead of a grounded neutral. This will not result in a false trip but will render that extra feature inoperative.
And that feature would not work on. I always recommend that you hire a qualified licensed electrician to perform any electrical work in your home. I share this video simply to give a very basic.
Hot Neutrals are only wrong half of the time. Since Ground is bonded it follows Neutral. This is not a Short Circuit in common home wiring schemes.
In a Balanced AC system 2. 60 volt secondarys with a common leg as Neutral With True Earth Ground A Hot Neutral Reverse at the outlet will Short the system and Fail on power up. If your outlets polarity is reversed it means that the neutral wire is connected to where the hot wire is supposed to be.
This may not sound like a terrible thing but it is. There is always electricity flowing out of an outlet with reversed polarity even if an appliance is supposed to be off. Why is it dangerous.
Hot neutral reverse outlets are outlets where the hot and neutral wires are in opposite positions. Hot neutral reverse outlets are a potential shock hazard. Electrical outlet defects should be evaluated and repaired by a qualified electrician.
Problems relating to the electrical system can result in serious hazards if not properly resolved. Electrical Lighting Expert. Aug 28 2010 0434 AM.
A hot and ground reversed reading on plug-in testers is usually an indication of an open neutral. As TK said it is rarely an accurate reading of the actual problem. The wire coming out of the panel is a 3-wire bx.
The circuit that the black wire feeds is just fine yet the circuit the red wire feeds gives us the reverseground reading. I know that can be an open neutral but if both hot wires are coming from the same cable shouldnt both show the open problem. Any idea what could be going on.
And if someone DOES work on it - testing to verify the wiring was done correctly should be performed BEFORE restoring power to the equipment. But if you want an automatic system to monitor it - thats your prerogative. J edit Looking at my drawing I see I forgot to label the Hot Neutral and Ground wires.
