The neutral wire is simply a grounded power carrying conductor.
It is different than earth ground, which is a protective ground, that is not intended to carry current, however, earth ground and neutral are connected together at the distribution panel. Nevertheless, they serve different purposes, and may not be interchanged in usage.
The purpose in grounding one of the power carrying conductors is to limit the possible voltage potential that might exist between an ungrounded conductor, such as hot, or phase hot, so as to minimize the potential electrocution hazard that might exist if someone were to come into conduct with a hot conductor.
What else can I help you with?
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
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 does the term floating neutral mean?
This could mean a couple of different things. At some point in the power distribution system, the neutral bus is normally tied to the ground bus. If the neutral is not grounded, this could be called a floating neutral. More often, the term is used to describe a load, such as a light fixture or motor where the neutral wire has accidentally not been connected. The hot wire is live, but the device does not function. The neutral wire normally provides the return path for current to flow. This is a very dangerous situation. The live voltage flows from the hot wire, through the load, then into the neutral wire. If the neutral is not connected (grounded), it becomes hot! Everyone knows the hot wire can bite you, but we normally expect the neutral to be dead. We may carelessly handle the neutral, thinking it is dead, but if it is floating (unconnected), it could be live. Many people have been killed in this fashion. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
When an ac bulb glows the phase wire gives a shock when touched by hand but the neutral wire doesn't?

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 function of a neutral wire in an electrical circuit?
The function of a neutral wire in an electrical circuit is to provide a return path for the current to flow back to the power source, completing the circuit and ensuring a balanced flow of electricity.
Do you need a neutral wire for a light to work?
In most cases, yes. A neutral wire is usually required for a light to work properly, as it completes the circuit and allows electricity to flow to and from the light fixture. If there is no neutral wire, the light may not function correctly or at all.
What is the purpose of the white wire in an electrical circuit and how does it function as the neutral wire?
The purpose of the white wire in an electrical circuit is to serve as the neutral wire. The neutral wire completes the circuit by providing a return path for the current to flow back to the power source. It is connected to the ground at the electrical panel to ensure safety and proper functioning of the circuit.
What is a floating neutral wire?
a loose connection of a neutral wire
How can I install a light switch without a neutral wire?
To install a light switch without a neutral wire, you can use a switch that does not require a neutral connection, such as a mechanical switch or a wireless smart switch. These types of switches do not need a neutral wire to function properly. Make sure to follow the manufacturer's instructions carefully when installing the switch to ensure it is done safely and correctly.
Does an outlet still operate with a failed neutral wire?
The ordinary household AC power requires "hot" and "neutral" wires to both function properly. A failed neutral is a potentially dangerous condition.
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.
Is the ridged wire neutral or hot?
If wired properly the ridged wire is the neutral.
What color is the neutral wire?
The neutral wire is typically colored white or gray.
Which side of the White neutral wire do you connect the Black power wire?
The neutral wire and power wire are never connected together.
Is the white wire in this electrical circuit designated as the hot wire or the neutral wire?
In an electrical circuit, the white wire is typically designated as the neutral wire.
Is the white wire hot or neutral in the electrical circuit?
In an electrical circuit, the white wire is typically used as the neutral wire, not the hot wire.
