A Neutral represents a reference point within an electrical distribution system. Conductors connected to this reference point (Neutral) should, normally, be non current carrying conductors, sized to handle momentary faults (short circuits) occurring in electrical equipment. A Ground represents an electrical path, normally designed to carry fault current when a insulation breakdown occurs within electrical equipment. (Note: Breakdowns can be forced by connecting (dropping) a metal tool or conductive material from a voltage potential to the steel structure within a facility).
What else can I help you with?
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 is the process of bringing a negatively charged conductor in contact with the earth resulting in the conductor discharge until it is completely neutral called?

What is a Grounded conductor?
The grounded conductor (Neutral) can be white or gray. The grounding conductor can be solid green, Green with a yellow tracer or bare copper.
GFCI circuitry often checks for a difference in current between the ground and neutral?
A GFCI monitors the current in the ungrounded (hot) conductor and the grounded (neutral) conductor. If there is more than 6mA of current difference between the two the GFCI will open the circuit.
The neutral conductor at sub panels must be?
The neutral conductor at sub panels must be isolated or kept separate from the grounding conductor to prevent the possibility of creating parallel paths for current flow. This separation helps to maintain the integrity of the grounding system and reduce the risk of electrical hazards.
What is difference between ground and neutral?
A neutral is an active conductor in the circuit. It is grounded at the source but that's for another discussion. The ground exists to ensure the proper operation of over current devices like fuses and breakers in the event of a fault.
Define earth voltage and neutral voltage?
As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures, so the installation of grounding conductors and neutral conductors is carefully defined in electrical regulations. Where a neutral conductor is used also to connect equipment enclosures to earth, care must be taken that the neutral conductor never rises to a high voltage with respect to local ground.
Why in electrical wiring you need both neutral and ground if neutral is zero voltage why you cannot used it as a ground?
The neutral is a current-carrying conductor, the grounding wire is not; it is for safety as an ALTERNATE path to ground. For example, if something happens to disconnect the neutral or if the hot side comes into contact with conductive portions of an appliance, the grounding conductor can save a life by providing a safe fault mechanism.
What is the difference between a Grounded conductor and a Grounding conductor?
In residential 120 VAC, single-phase electrical wiring, there are three main types of electrical wires: 1. Ungrounded conductor (Hot, and sometimes called "Line" or "Phase") 2. Grounded conductor (Neutral), and 3. Grounding conductor (Safety Ground or Protective Earth) The groundED conductor is the power return, intended as a current return path from the load back to the source to complete the "circuit." Its insulation is White, gray or a non-green color with white stripes. The National Electric Code requires it be connected to earth ("groundED ") at the service entrance and usually only there. The groundING conductor is usually the safety ground which serves as an emergency current return path in the event of a circuit fault or overvoltage. Like the groundED conductor, it too is grounded at the service entrance, but is also connected to metal surfaces and parts along the circuit, groundING them. It conducts current only if the current "seeks" to return to the service entrance along a path other than the Neutral (like through your chest, should a Hot wire becomes loose and contact metal in the circuit that you may touch). Since the grounding conductor doesn't normally carry current, its cross-section is sometimes smaller than the groundED conductor's. The grounding conductor's insulation is green (no other conductors can have green insulation) though sometimes it is bare copper. Sometimes the steel metal conduit enclosing the Hot and Neutral acts as the grounding conductor.
What is the difference between a ground bar and a neutral bar in an electrical panel?
A ground bar is used to connect the grounding wires of electrical circuits to the panel's grounding system, while a neutral bar is used to connect the neutral wires of electrical circuits to the panel. The ground bar is for safety, while the neutral bar is for completing the circuit.
Is a grounding 120 volt receptacle larger than an ordinary receptacle?
No, it just has an additional conductor to separate the neutral from the ground, and has a third prong in the receptacle to receive the appliance grounding conductor through the cordset.
What is meant by neutral grounding reactor?
Neutral-earthing reactors or Neutral grounding reactors are connected between the neutral of a power system and earth to limit the line-to-earth current to a desired value under system earth fault conditions.
