# Does a neutral wire have a voltage?

## Does a neutral wire have a voltage?

In the electric power grid, “neutral” is ground, by definition. So the voltage of the neutral wire is always zero… By definition.

How much voltage is in a neutral wire?

4 Answers. The neutral wire is defined to be 0V. And each phase individually has a voltage relative to neutral of 115V if you are in the US, and 230V if you are in most of Europe.

### Does the neutral carry power?

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 a neutral wire be connected to ground in panel?

When Should Grounds & Neutrals Be Connected in a SubPanel? The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.

#### Does a neutral wire have voltage on it?

A true neutral will have no voltage on it.. but what we usually call a neutral (because it’s the white noodle) is really just a return for the hot conductor. It’s the load side of the hot conductor. If you open that while voltage is still being supplied on the line side, you can let the smoke out of electronics.

Is the neutral wire connected to earth potential?

Keep in mind however, that even though the neutral wire might be connected to earth, this doesn’t mean that it is actually at earth potential, because a return current might be flowing in the neutral wire, and due to the resistance in the wire this will cause a voltage at your end of the neutral wire.

## Why doesn’t the neutral wire go back to the transformer?

Doesn’t the neutral wire go back to the transformer so as to provide a closed circuit? The neutral wire is defined to be 0V. And each phase individually has a voltage relative to neutral of 115V if you are in the US, and 230V if you are in most of Europe.

Why is it important to positively identify and turn off neutral wires?

This is why it is extremely important to always positively identify and turn off any electrical circuit that you may be working on, even if you are working on just the the neutral wires, because if you become grounded or caught in the middle, your sure to get shocked, and this is called Not Fun!
