Quick Answer: Can I Pull A Neutral Wire From Anywhere?

Is a open neutral dangerous?

Yes, an open neutral on a two wire circuit will just open the circuit and disconnect the load.

Both are dangerous, especially the service neutral sine it effects all 120 volt loads in the house..

Should there be voltage on the neutral wire?

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.

Why is 240V not neutral?

The grounded (neutral) conductor is connected to the center of the coil (center tap), which is why it provides half the voltage. Therefore, if a device requires only 240V, only two ungrounded (hot) conductors are required to supply the device.

Can you get a shock from the neutral wire?

So even the current returns through neutral (only from a connected load that completes the current flow circuit) you touching the neutral with a 0V cant get you a shock. But its not safe to touch neutral wire! … Some voltage between earth and neutral(at a high potential) can give you a shock.

Can two lights share a neutral?

1 Answer. If they are all on the same circuit, yes. … If one circuit breaker turns off all three lights, then they are on the same circuit and you should be good to go.

Do light switches have a neutral wire?

Neutral Wire. The neutral wire provides power to the light switch, even when the lights are off. (A neutral wire does not control the lights.) … Neutral wires are typically white and may be found bundled inside the back of the switch box.

What happens if earth and neutral wires touch?

In Short if neutral wire touches a earth wire, An earth wire carrying load current is a risk of electric shock because a person touching this earth may present an alternative path for the load current and thus the risk of electric shock.

What causes voltage on a neutral wire?

The wire used in electrical distribution systems is usually made of copper. … When the wire length from the breaker panel to the service outlet is long and the connected equipment is pulling a large amount of current, the resistance in the wire will cause a voltage drop along the NEUTRAL wire.

Where does the neutral wire go in a breaker box?

In the sub-panel box, the neutral and ground wires will connect the same as they do in the main breaker box, but the red and black wires will connect to the hot bar instead of a circuit breaker. Find the ground bus bar. It is a metal strip with a row of screws running down it.

What color wires are neutral?

White or gray wires indicate neutral charged wires.

Does the neutral wire carry current?

Neutral wire definitely carry current. It is used in AC current for return path or you can say to complete circuit.

Can a neutral wire be connected to ground?

No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. … However, if there is something wrong and the neutral is disconnected, it will make the appliance dangerous.

What happens when neutral wire is disconnected?

If the neutral wire is broken or disconnected, the out of balanced current cannot return to the supply through the star point, but it must return. So, this current takes the path back to the supply through the lines.

What is the purpose of a neutral wire?

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.

Can two circuits share a neutral?

It is NOT permitted to share a neutral in any other situation. If you were to share a neutral with two breakers on the same leg of a panel, both circuits could draw the breaker limit (lets say 15A) making the shared neutral as much as 30A return current!

What happens if transformer neutral is not grounded?

Neutral failure at transformer is mostly failure of Neutral bushing. … Under normal condition current flow from Phase to Load to Load to back to the source (Distribution Transformer). When Neutral is broken current from Red Phase will go back to Blue or Yellow phase resulting Line to Line voltage between Loads.

Can I use a neutral from another circuit?

No, you can’t steal a neutral wire from another circuit. Each neutral wire is the return for the corresponding hot. If you “steal” a neutral from another circuit you run the risk of overloading that neutral wire (overheat, fire risk).

Can 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 is the difference between ground and neutral?

A Neutral represents a reference point within an electrical distribution system. … A Ground represents an electrical path, normally designed to carry fault current when a insulation breakdown occurs within electrical equipment.
