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.
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.
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 !!!!
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.
The neutral wire should be the same size as your conducters
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.
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.
Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.
The three wires in a plug are typically called live, neutral, and earth wires. The live wire carries the current to the appliance, the neutral wire completes the circuit and carries the current back, and the earth wire is a safety feature to prevent electric shocks.
To test a neutral wire, use a multimeter set to measure voltage. Place one probe on the neutral wire and the other on a ground wire or metal box. A properly functioning neutral wire should show a voltage reading close to zero. If the reading is significantly higher, there may be an issue with the neutral wire.
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
mee too in the same situation. anyone help us out pl.
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.

To determine the location of the neutral wire in an electrical circuit, you can use a voltage tester or a multimeter to identify the wire that carries little to no voltage compared to the hot wire. The neutral wire is typically connected to the ground or earth in the electrical panel. Be sure to turn off the power before attempting to locate the neutral wire for safety.
To test the neutral wire in an electrical circuit, you can use a multimeter set to measure voltage. First, turn off the power to the circuit. Then, place one probe of the multimeter on the neutral wire and the other probe on the ground wire. If the multimeter reads a voltage close to zero, the neutral wire is functioning correctly. If there is a significant voltage reading, there may be an issue with the neutral wire.
Current needs a return path to earth to flow. The neutral carries this flow. Therefore, no neutral and no current flow.
