Earth is neutral, but only at the distribution panel and upstream from it. Downstream of the distribution panel, earth and neutral shall not interchange or cross connect their connections or their roles - earth is protective ground - and neutral the current carrying return conductor.

∙ 12y agoEarth is a protective ground that is not intended to carry operating current. Neutral, on the other hand, while grounded at the distribution panel and at the service entrance, is intended to carry operating current. As such, neutral is properly insulated and designed to rise to the same temperature as the hot conductors, while earth is not. Also, many ground-fault-current-interrupting (GFCI) breakers operate on the principle of differential current between hot and neutral - returning current back on earth instead of neutral will cause those breakers to trip.

∙ 13y agoNeutral should only be connected to earth (ground) at the main electric panel. You should NOT use earth in lieu of neutral.

Can loose neutral wire effect the operation of Earth Leakage Circuit Breaker?
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.
Can you use the earth wire between room stat and honeywell board as a neutral?
ABSOLUTELY NOT!The protective earth ground wire is only there to provide a low resistance path to ground in the event of a short circuit so as to trip the protective device. Operational current is never, under any circumstances allowed to be passed on earth ground. Use neutral for neutral and ground for ground.CONSULT A QUALIFIED AND LICENSED ELECTRICIAN !!!!
Why can the neutral wire diameter be reduced in relationship to the phase wires?
The Neutral wire should be the same gauge and size of the phase wires. Only the Earth or Equipment wire can be smaller than the phase(hot) wires. <<>> On a three phase four wire distribution system the neutral can be reduced in size. The neutral only carries the unbalanced load current and should be sized to that current. The highest current load to neutral of the three legs is used to calculate the neutral sizing. There is no reduced neutral allowed on discharge lighting and non linear loads. A demand factor of 70% shall be permitted to be applied to that portion of the unbalanced load in excess of 200 A.
What is the permissible neutral current?
I think you mean "what is the permissible imbalance between live and neutral current" All current supplied by the live wire should exit via the neutral. Any imbalance leaving via Earth is detected by an earth leakage circuit breaker . They trip at about 30 mA.
When upsizing wire for voltage drop how much smaller can the neutral wire be the next phase conductor?
The neutral wire should be the same size as your conducters
What position would you find live electrical wire?
You would find a live electric wire, with a neutral and usually also an earth wire, in any place where electricity is used. The wires are colour coded differently in different areas but in Europe live is brown, neutral is blue and earth is green/yellow.
Can loose neutral wire effect the operation of Earth Leakage Circuit Breaker?
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.
What colors are electrical wires with number reference?
eletrical wire has 3 specif colour coding. As live wire ,neutral wire,earth wire. 1.live - red 2.neutral-black 3.earth - green. These are the specific color coding of eletrical wire.
How do you reduce neutral to earth voltage in three phase system?
It is done by connecting the neutral to earth at the transformer that produces the three-phase supply. If the three phase wire supply equal currents, there is no current in the neutral wire and its whole length stays at earth potential, but if there is current in the neutral it produces a small voltage on the neutral at places away from the transformer.
What are the three wires in a plug called?
The green and yellow is the earth wire The brown is the live wire The blue is the neutral wire A poem to help is: The brown live cow drinks from the blue neutral water and eats the green grass from earth
How do you identify neutral and ground or earth wire means if someone has changed the terminals of wire then how will we identify which one is neutral and which one is earth?
mee too in the same situation. anyone help us out pl.
Can earth wire be used as a neutral wire?
No, an earth wire has a specific safety role in an electrical circuit that does not allow it to be used as one of the two current-carrying wires.
Color code in 3 pin electric plug in India?
Green with Yellow Stripe Wire - Earth Wire (E) Blue Wire - Neutral Wire (N) Brown Wire - Live Wire (L) When you look at the plug with the terminals facing towards you: /\ / \ / E \ / \ / \ / L N \ ------------------
What will happen without a neutral wire?
Current needs a return path to earth to flow. The neutral carries this flow. Therefore, no neutral and no current flow.
How do you wire a UK socket?
The following applies to the UK Blue wire goes to neutral Brown wire to live Yellow/Green stripe wire to earth
What happen if you connect earth wire in place of neutral wire?
If there's no earth leakage protection unit in your main Distribution Board then the device will operate normally since the neutral and earth conductors are one on the supply side. But if there's Earth Leakage then because of the imbalance in the currents flowing through the Earth Leakage it will trap. What is called 'earth wire' in Europe is called 'ground' in the US and is often bare. Using a bare conductor as a neutral exposes you to potential shock. If the bare wire is properly connected at the panel, all is fine. But if you touch this bare neutral and provide a better grounding connection than the panel provides, you become part of the circuit to whatever device that circuit supplies. What is often missed in this scenario is that with the neutral being after the load, the load limits the current and your shock WILL NOT TRIP THE BREAKER.
What devices get a neutral wire?
All devices use two wire, the live and the neutral. These carry the current used by the device. Most devices also have an earth wire for safety, which carries no current until a fault occurs and then the fault current in the earth wire might save someone from being electrocuted.
