the hot wire in the circuit has come in contact with a ground

-------------------------------------------------------------------------------

not true, if a circuit is grounded properly the outside ( as in the outside of a drier ) is connected to the ground to prevent shocks . it gives electricity a route to go that is away from you.

<<>>

The first answer is correct, because the circuit is grounded. The second answer refers to equipment grounding for safety reasons.

<<>>

The first answer is a short circuit which will blow a fuse or trip a circuit breaker.

If a circuit is grounded in AC it's for saftey like the second answer, in DC it's the route the electricity takes back to the battery from the circuit.

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.


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.


Is a metal window frame a circuit conductor?

No, a metal window frame is not a circuit conductor unless it is intentionally part of an electrical circuit. In standard construction, metal window frames are typically grounded and do not conduct electricity.


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 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.
