The grounded conductor (Neutral) can be white or gray. The grounding conductor can be solid green, Green with a yellow tracer or bare copper.
What else can I help you with?
What happens when there is no plastic coating on a electrical wire?
Nothing happens. The wire will still conduct electricity. An example of this is the overhead utility wiring. The insulation on a conductor is there strictly to keep the conductor from touching any thing that would ground the conductor. This grounding could be from another adjacent conductor or a grounded medium around the conductor. A grounded conductor will trip the over current protection and trip the circuit off line. Without an insulation on the wire multiple wires in a conduit could not be utilized.
What is multiwire branch circuit?
A multiwire branch circuit is consist`of two or more ungrouded conductors that has voltage between them and has a grounded conductor that is eoual voltage between each conductor connect to the neutral and it,s ground
What is an grounding electrode conductor?
It is the conductor that is used in service distribution panels that bonds the distribution panel's neutral bus bar to the ground electrode (rod). This brings all of the distribution panel neutrals that are connected to the same supply system to the same potential, that being zero. Should a supply service neutral open this ground wire will maintain the systems integrity until repairs can be made.
What is the purpose of grounding electrical equipment?
It is a safety measure for devices that have a metal case where a failure in the device could cause the case to be connected to the hot side of the circuit. By grounding the case the breaker will trip instead of you getting a shock.
What is the process of bringing a negatively charged conductor in a contact with the earth resulting in the conductor discharging until it is completely neutral called?
The process is called grounding. Many devices need to be grounded, hence the U shaped pin on a devices that make contact with the ground in normal house wiring.
What color wire is a grounded conductor?
Grounded conductor is white 120/240 volt & gray 480 volt. Grounding conductor is green or green with yellow.
Where the ground wire located?
The grounded conductor is usually covered in white or light gray insulation. The grounded conductor is connected to the grounding conductor at one and only one point, usually near the transformer or in the circuit breaker panel.
Why does copper wire have to be insulated?
To stop the conductor from touching adjacent grounded structures.
Does the grounded conductor have normal circit current flow?
Yes, the grounded conductor carries normal circuit current flow in a typical electrical system. It provides a return path for current back to the source, completing the circuit.
What color is a grounded conductor?
A grounded conductor, typically the neutral wire in an electrical system, is usually colored white or gray. However, in some cases, it may be a different color depending on local electrical code regulations.
The identified grounded circuit conductor is what color?
The identified conductor is white or natural grey in color. If you are using a zip cord (Lamp cord) is is the conductor with the ribs on it.
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.

Can static electricity build up on an earthed conductor?
No, static electricity cannot build up on a conductor that is properly grounded (earthed). Grounding provides a path for the excess charge to flow into the earth, preventing the accumulation of static electricity on the conductor.
What is the difference between a phase to ground connection and a grounded wye connection?
A 'grounded-wye' connection describes a wye-connected supply, whose star-point (or common point) is grounded. This is essential in order to ensure stable phase voltages. I'm not sure what you mean by a 'grounded-phase' connection; if you mean a 'grounded-line' connection, then this is a short-circuit to ground from a line conductor.
What is OSHA definition of grounded?
OSHA does not provide a specific definition of "grounded." You should use the commonly accepted definition in the electrical industry. That is, a conductor that has a secure conductive path to ground, or "earth" as the term is used in the UK
What conductor should be grounded in a four wire three phase system?
The neutral conductor is typically grounded in a four-wire three-phase system to provide a path for fault currents to return to the source and to stabilize the system voltage. Grounding the neutral also helps to protect equipment and personnel from electrical hazards.
