Why do I have 120v on my neutral?
If you have aneutral wire
Neutral is a circuit conductor that normally completes the circuit back to the source. Neutral is usually connected to ground (earth) at the main electrical panel, street drop, or meter, and also at the final step-down transformer of the supply.

Why is there 120 volts on the neutral?
In a normal situation with the neutral path intact, you would have 120 volts measured from across the light bulb or the receptacle. In this case, both sides of the light (hot and neutral) are the same, thus no potential difference (voltage), and the bulb does not light up.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.Should there be voltage on neutral?
This is a common question that one would think should have a simple answer, but that is not actually the case. The neutral wire is often said to have zero voltage on it.Should there be 120v between neutral and ground?
You have to measure neutral-ground or hot-ground. If neutral-ground voltage is about 120 V and hot-ground is a few volts or less, then hot and neutral have been reversed. Under load conditions, there should be some neutral-ground voltage - 2 V or a little bit less is pretty typical.Understanding an Open or Loaded Neutral
Why do I have voltage on my ground wire?
Stray voltage occurs when electricity “leaks” from the black wire directly to the white or ground wires before passing through the device to be powered. These leaks produce only small amounts of electricity. Direct contact between the white and black wires would “short” the system and blow a fuse or circuit breaker.Does neutral wire have power?
To summarize: the hot wire carries electricity from the power supply and takes it to the load (lightbulb). Neutral wires take the used electricity from the load and bring it back to the power supply.Why would my 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). Look for a disconnected neutral.Can I get shocked from a neutral wire?
The neutral wire does have current going through it. However, we do not get shocked when we touch something with current going through it, we get shocked when current goes through us. In this case all of the current that enters one end of the section of wire we are touching also leaves the other end.Why neutral has current?
Neutral wire carries the circuit back to the original power source. More specifically, neutral wire brings the circuit to a ground or busbar usually connected at the electrical panel. This gives currents circulation through your electrical system, which allows electricity to be fully utilized.How much current does the neutral wire carry?
On any individual circuit (lamp or 120V outlet) the current in the neutral in that circuit is equal to the current in the "hot" wire.Should a neutral wire be live?
Neutral is not necessarily zero and assuming it is will likely get you electrocuted. The general idea is that live supplies the voltage and neutral is the return wire. In most installations the live is at the required voltage and the neutral line is connected to ground at some point (so zero volts relative to ground).What happens if you mix up hot and neutral wires?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it's usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.Can I use neutral as ground?
a ground and a neutral are both wires. unless they're tied together with other circuits, and not a 'home run' back to the panel, there is no difference between the two where they both end up on the same bus bar in the box.What happens if live wire is connected to neutral?
In an electric iron being used in a household, the plastic insulation of live wire and neutral wire in the connecting cable gets torn. Due to this, naked live wire touches the naked neutral wire directly and the electric fuse of the circuit blows off.Can you live wire neutral together?
When a live wire and neutral wire come in direct contact, what happens? It is the condition of the short circuit if the live wire directly comes to the neutral wire. ... If Normal wire burns, the circuit will break and everything will become normal except for that wire.Does current flow on the neutral?
Re: Neutral has 0 voltage, so how does current flow? Current flow just requires a voltage difference. As long as the "live" cable has a positive or negative voltage relative to to the neutral cable, current will flow.Does neutral wire carry amps?
Moderator. The neutral carries the umballaced current, it would be a long shot to ever read zero amps on a neutral in a panel.Can you connect neutral to ground bar?
The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.What happens if neutral is not grounded?
Grounding neutral provides a common reference for all things plugged into the power system. That makes connections between devices safe(r). 2. Without a ground, static electricity will build up to the point where arcing will occur in the switchgear causing significant loss in transmitted power, overheating, fires etc.Can a hot and neutral wire touch?
A short circuit happens when a “hot” wire (black) touches another hot wire or touches a “neutral” wire (white) in one of your outlets. When these two wires touch, a large amount of current flows, creating more heat than the circuit can handle, so it shuts off.Does neutral wire go back to power plant?
Electric current always flows from a power supply to the equipment that is using it and then back to its source, completing a circuit as it moves along an electrical supply system. Every electrical supply system uses a neutral conductor to return the current to the supply source.Can neutral wire be bare?
3: The grounded neutral conductor shall be permitted to be a bare conductor if isolated from phase conductors and protected from physical damage.
