The purpose of neutral conductor is to carry the unbalanced load current. It is also a grounded conductor, which effectively places a limit on how much voltage could be present from hot to ground, a safety concern.

∙ 15y agoThe Simple Answer? -- All electricity runs in a circuit. In a DC system, this is from the positive terminal of a battery to the negative. In an AC circuit, the Neutral actually connects to the Earth ground through a grounding rod or some other method, completing the circuit (the Generator is also grounded at the other end -- so the earth is really just a GIANT conductor).
A grounded AC system has three wires:
HOT (generally black, red, or blue)
NEUTRAL (primary ground) (generally white)
GROUND (secondary ground) (generally green or unshielded)
The secondary ground (sometimes called a chassis ground) is in case there is a failure of the NEUTRAL. The last thing you want is for the electricity to complete the circuit through your body -- so the secondary ground is used because it has lower resistance and electricity always follows the path of least resistance.

is connected to ground at Main Panel which is bonded to earth ground.
The neutral is the return path back to the utilities transformer and is bonded to the grounding conductor at the main service equipment.

Why you need neutral conductor?
To complete the circuit. The word neutral is a convention it does not mean it has no purpose
What does a hot terminal do?
A 'hot' terminal is a slang expression for the line terminal of an AC supply. In Europe, for example, a single phase supply to a building has three conductors: line conductor, neutral conductor, and protective (earth) conductor. The line conductor has a potential of 230 V with respect to the neutral; the neutral conductor is at approximately the same potential as the earth conductor. In North America, there are two line conductors, which are at 240 V with respect to each other, and at 120 V with respect to the neutral.
Can a neutral conductor be broke in a disconnect?
The neutral can be broken in some installations. One example is when wiring explosion proof equipment.
What is an AC single phase 2 wire system?
two wires coming off the secondary of the transformer ex. residential voltage of 120 volts each line, and one neutral wire, L1 to neutral is 120 volts, L2 to neutral is 120 volts, L1 to L2 is 240 volts.AnswerA single-phase, two-wire, system comprises a line conductor and a neutral conductor. In European countries, the line conductor for a residential supply is at a nominal potential of 230 V with respect to the neutral.In North America, a 'split phase' system is used for residential supplies; this is a single-phase, three-wire, system comprising two line conductors which and a neutral conductor. The nominal potential difference between the line conductor is 240 V, while the potential of each line conductor with respect to the neutral is 120 V.
Why link is provided as neutral in an ac circuit?
link is provided in neutral path of ac supply because it should provide a path for unbalanced currents , if we use fuse ,fuse may blow of and damage the entire system and also unbalanced currents may be more than the fuse rating
Why you need neutral conductor?
To complete the circuit. The word neutral is a convention it does not mean it has no purpose
What is the purpose of neutral contactor?
Presumably, you are asking the purpose of a neutral conductor, rather than 'contactor'?A alternating-current supply has two conductors, a lineconductor and a neutral conductor. The line conductor is at system potential (e.g. 230 V in Europe), whereas the neutral conductor is at approximately earth (ground) potential because it is earthed (grounded) at the supply transformer. The neutral conductor acts as the 'return' path to the transformer, carrying the same load current as the line conductor.
What two colors may be used for the ground conductor neutral?
What two colors may be used for the ground conductor (neutral)
How are voltages imported into installations through the supply neutral conductor?
A 'voltage' is another name for a potential difference. As the name implies, a potential difference exists between two different points or, in the case of an electrical installation, between the line conductor and the neutral conductor. So the neutral does not 'import voltages'. Voltages exist between the line (hot) conductor and the neutral conductor.
What are the property of good conductor?
a good conductor should be electrically neutral.
What type of circuit is it that has a hot conductor contacting a neutral conductor?
A shorted circuit.
What is the difference between a neutral wire and a hot wire?
In alternating-current systems, we don't have a 'positive' and a neutral conductor, but a 'line' and a neutral conductor.The neutral conductor is connected to the earth and, so, has a potential of approximately zero volts.The line conductor, on the other hand has a potential of approximately 230 V (in Europe) or 120 V (in North America) with respect to the neutral conductor. For this reason, line conductors are frequently referred to as being the 'hot' conductor.
What is meant by PEN conductor when referring to earthing of supply system?
Conductor combining the functions of both a protective earthing conductor and a neutral conductor

What color are the phase neutral and earth cores in flexible cords?
It depends on the electrical standards of the country in which you live. In Europe, for example, the line conductor(not 'phase conductor'!) is brown, the neutral conductor is blue, and the earth conductor* is green/yellow stripe.[*properly called a 'protective conductor']
Why neutral solution is not a good electrical conductor?
neutral solution does not contain free ions.
Why half size of neutral conductor in 3.5 core cable?
Because neutral doesn't have to carry the load current .This is either used for unbalanced current (in Y-connection) or for earthing purpose which don't require high ampere rating....
