Answer for USA, Canada and countries running a 60 Hz supply service.
240 volt two wire circuits loads do not need a neutral to operate. A three wire 240 volt circuit that needs a neutral, will have a neutral the same size as the current carrying conductors. In this case a #10.

Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
Originally a 240V line running from the 50A circuit to a box contaning in line fuses from this box came a 240V cable having 2 black wires and wire braid do I wire the outlet stove as a 3 or 4 prong?
3 prong the 2 black wires are your hot and the braided is your neutral.
Why are the live wire and neutral wire never joined together?
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
Would the black wire be line 1 on 240V line in?
On a 240 volt circuit both line wires are hot, so they may both be black, depending on the wire used. There is normally no neutral required unless you are also tapping off 120 volts between hot and neutral.
How do you hook up a 3 wire water herter to 4 wire circut?
4 wire household wiring is black, red, (hot wires) white (neutral) and bare or green (ground wire). You say 3 wires. Is it 120v or 240v. If its 240v which is more common just use the two hots and the ground and cap off the neutral wire.

How do you wire a single phase 240V tanning bed?
You can not, a new circuit will have to be run from the electrical panel. Tanning beds which require four wire circuits, need a grounded conductor (neutral) that is not available with a three wire circuit.

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.
How many neutral wires are needed for lighting and outlets?
If they are on the same circuit you only need 1 neutral wire in the circuit.
What does an open neutral mean?
Typical home wiring will have one hot wire, one neutral wire, and one ground wire per circuit. An open neutral would indicate that the neutral wire, usually white wire, is broken.
Why don't you need a white wire when wiring a 240v a c unit?
White wire is usually used as a neutral conductor and a 240v ac unit has no neutral. Each leg of the 240 volts is a "hot" leg However, very often a 12/2 or 14/2 NM cable is used to power small window ac units using 240v. In this case one of the conductors is white, but is not a neutral. It is good practice to mark the white wire with black tape so it is readily identified as a hot wire.
On a 220 volt circuit where the white wire is common how many volts would the red wire be?
3 OR 4 . you only need 2 wires for 220, 1 phase is 120v between 2 of them its 220v . you also should have a ground for the third wire ,and the newer stuff requires a neutral or white wire for the 4th wire. hope i helped , D
What does neutral wire failure do?
Neutral wires are actually ground wires. They enable the circuit to be completed.
