Does Neutral Wire Have Voltage

Live neutral and earth are labels that are used to convey some information on the use of each wire.

Does neutral wire have voltage. Neutral conductor of a 3 phase 4 wire system and the middle conductor of a 2 phase 3 wire system to have minimum two separate and distinct earth connections with a minimum of two different earth electrodes to have the earth resistance to a satisfactory value. One of the outlet has no power in my house. Try disconnecting turning off all other loads on that circuit. The answer ront gave about the phantom voltage esentially means you really have no voltage on the neutral wire.

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. But you do if you are grounded and then touch the white wire. You most likely have an open somewhere else down stream towards the main panel of the non working receptacle. In contrast the ground wire is connected to any metal parts in an appliance such as a microwave oven or coffee pot.

A 120 volt reading will be noticed if voltage tester leads are placed between either two hot wires or two neutral wire when the circuit is on and under load. It is not recommended that this procedure is performed unless you understand what you are doing because getting in the middle of any live circuit can cause an electrical shock which could be fatal. Why am i getting 120 volts from a neutral wire. Some of the worst shocks i have ever received while working on live circuits was from neutral wires here is why and how you can prevent electrical shock from a neutral wire.

You can verify this by taking the measurement using an analog meter and not a digital meter that ll be the telling tale. This should make the neutral voltage disappear. However the neutral and ground wires serve two distinct purposes. 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.

There are only two wires no ground wire involved. In a normal situation with the neutral path intact you would have 120 volts measured from across the light bulb or the receptacle. Neutral and live both hot when switch is turned off. The neutral wire is defined to be 0v.

The wiring in the house is very new. I found the neutral wire is also hot like the black wire. Like the neutral wire the ground wire is also connected to an earth ground. The neutral wire forms a part of the live circuit along with the hot wire.

You are correct in thinking that in a typical two wire ac loop circuit both wires carry the same amount of current amps. So both wires could be considered live wires. In a 3 wire circuit the neutral wire is created when you have a power source that is center tapped ct thereby creating. The earth electrodes to be inter connected to reduce earth resistance.

The voltage you are seeing on the neutral wire is conducting through that other load from the hot. But because the three phases are 120 deg out of phase compared to each other this results in a voltage difference of 115v sqrt 3 200v or 230v sqrt 3 400v between any two phases.
