One is whether the hot or the neutral is open. The other is the extent of the outage compared to the extent of that circuit. If a tester reveals Hotness still present at more than one dead item of the circuit (at the shorter slot of receptacles or the tongue in the bottom of a turned-on standard light socket, for instance), the neutral is open.
Full Answer
What is an open neutral?
An open neutral occurs when the neutral wire has a loose connection between two points. Electrical current flows through the hot wire to powers receptacles, lights, and appliances. The neutral wire completes the circuit path back to the electrical panel.
What is hot and neutral reversed?
Hot and neutral reversed is the incident of mixing the hot and neutral connections. This phenomenon is also known as reverse polarity. The neutral common wire should be connected with the ground.
What is an open neutral on a 120V outlet?
The neutral allows appliances that need 120 volts to access the supply without hitches. When it’s an open neutral, it means that it is activated. The process carries electric flow to appliances instead of returning to the panel.
How can you tell if a neutral wire is open or closed?
The other is the extent of the outage compared to the extent of that circuit. If a tester reveals Hotness still present at more than one dead item of the circuit (at the shorter slot of receptacles or the tongue in the bottom of a turned-on standard light socket, for instance), the neutral is open.
Why would a neutral wire be hot?
If the neutral is disconnected anywhere between the light bulb and the panel, then the neutral from the light to the point of the break in the neutral will become hot (and the device will be unpowered, because no current will be flowing through it).

What causes an open hot outlet?
What Causes an Open Hot? Overloads are the most common cause of an open hot. When household appliances or devices draw more power than the voltage on the distribution service panel, the circuit breaker might trip, or the wire that supplies electricity could go loose because it can't support that amount of voltage.
What does it mean when a plug is open hot?
An open hot reading on your outlet tester means that the wire that should be 'hot', or connected to power, isn't getting any power. There could be a couple of reasons for this. If the outlet reading as open hot is connected to a switch, the switch could just be in the off position.
Can a bad receptacle cause an open hot?
The Causes of an Open Hot Usually an open hot results from a bad connection at a receptacle, switch, or light fixture.
Why does my neutral wire have voltage?
The voltage you are seeing on the neutral wire is conducting through that other load from the hot. Your voltage tester is detecting voltage without drawing current so the resistance of the other load is not seen. Try disconnecting/turning off all other loads on that circuit.
How do you fix a hot neutral reverse?

Will an outlet work with an open neutral?
If there's an open neutral, the outlets won't work, but they will still be energized. Use a plug-in circuit tester to check for an open hot or open neutral. If a string of lights or outlets tests for open neutral, you'll probably find the disconnection in the device closest to the panel.
Why is my outlet warm with nothing plugged in?
Sometimes homeowners come across outlets that are too hot to touch even when nothing is plugged into them. A hot outlet indicates an issue that requires immediate attention. It can happen due to loose or corroded wires, wetness, or unplugging something from an overloaded outlet, and may even result in a fire.

What Is Meant By Open Neutral?
Open neutral means the white wire (neutral) in a 120-volt circuit in your house is broken. If the neutral breaks, the circuit is incomplete because no electricity returns to the panel.
Is It An Open Neutral Bad?
An open neutral is terrible; in fact, it is dangerous. When there’s a loose wire connection, the neutral wire becomes abnormally hot and damages appliances in their wake.
What Happens When A Neutral Fails?
A neutral wire breakage will cause an electric shock. Any device connected to the circuit will get high voltage and probably overheat in the process. And this is very dangerous for your appliances and people in the house.
How Do You Troubleshoot An Open Neutral?
Fixing an open neutral is best done by a professional. It’s best to call an electrician if you notice any problem with your home’s electrical systems. But, as an initial troubleshooting step, you can identify the exact issue through 2 simple steps we will discuss below.
Can A Breaker Cause An Open Neutral?
If you have an irregular connection on the electrical outlet, it causes an open neutral downstream. In most cases, this happens especially when electrical outlet connections are employed to create a path for the neutral.
Final Thoughts
Several ways can cause an open neutral in your home wiring. Once you confirm an open neutral, you can begin the process of troubleshooting. In complex wiring, troubleshooting is a lot of work.
What does it mean when a tester reveals hotness?
If a tester reveals Hotness still present at more than one dead item of the circuit (at the shorter slot of receptacles or the tongue in the bottom of a turned-on standard light socket, for instance), the neutral is open.
Can an open hot panel be used on more than one circuit?
However, an open hot leaves you in the dark about what circuit you are dealing with -- unless you trust the labeling at the panel to be true and thorough. (In fact, your outage may extend to more than one circuit if one of the main wires is having trouble at your panel, the meter, or the power company's line; however, ...
What does it mean when a wire is hot?
When a wire is open and hot, that could mean it's come loose from its circuit. This is commonly seen in situations where outlets aren't giving out power, as the connections have come loose.
What happens if you leave a hot wire open?
Leaving an open hot wire could cause problems in your wiring system. Beyond that, though, if a wire is not supposed to be open and hot, there is a risk that it could start an electrical fire.
What is an open wire?
Open. An open wire, in the sense of wiring in a home, is one that is not connected to a circuit. When a circuit is closed, electricity flows through it and when that circuit is open, no power flows.
