An earth or ground conductor that is used for continuity throughout the home is the ground conductor that is found in cable wire sets. What it is used for is to bring everything that it is connected to down to the same potential which is zero. The grounding circuit is a low impedance circuit. If a fault occurs on any equipment and shorts out to ground, this conductor being directly connected to the distribution panel, carries the fault and trips the breaker feeding the faulted circuit.

Where does earthing current go?
it takes the lowest resistance path back to the current source Answer: Earth leakage current flows down to earth through the consumer earth continuity conductor.
What is the difference between a ground conductor and a ground electrode conductor?
# A ground electrode conductor is a conductor that originates at the neutral or equipment ground buses in the main service entrance panel board or separating derived system (e.g. isolation transformer) # A ground electrode is a item that is in contact with the earth (e.g. Building metal frame, underground continuous metallic water pipe etc...) # A ground conductor is a conductor that is used to keep an electrical system continuous. Ground conductors are required, by code, in all PVC conduit runs. Ground conductors are also used to keep all metallic components of the installation at the same zero potential to overcome mechanical connections that would not carry a fault current back to the supply distribution panel.
What is meant by ground fault?
The ground ('earth'), because of its mass, is a reasonably-good conductor and is used as a 'reference' for a distribution transformer's neutral terminal. A ground fault ('earth fault') occurs when the line conductor from the distribution transformer makes accidental contact directly with the ground ('earth'). The resulting low-resistance earth path back to the transformer's neutral is such that the resulting ground-fault current('earth-fault current') will operate the transformer's overcurrent protection device (e.g. fuse).
Why earth wire is green and yellow stripped colour?
The ground conductor is colored green to be identifyable anywhere in the circuit
What two colors may be used for the ground conductor neutral?
What two colors may be used for the ground conductor (neutral)
What is the meaning of ecc in electrical?
ECC stands for Earth Continuity Conductor. It is a grounding component of the electrical system. An ECC can be a bare conductor, a single conductor or a part of a multi-conductor cable.
What is ecc in electrical cabling?
This is the earth continuity conductor, which links the earth busbar in the consumer unit to the earth terminal provided by the supply company.
A conductor directly connected to the Earth?
GROUND
What are the faults in the cable?
Cable faults are normally categorised as (a) conductor-to-earth (ground) faults, (b) conductor-to-conductor faults, and (c) conductor-to-conductor-to earth (ground) faults. In addition to that, we can categorise them by whether they are 'high-resistance' or 'low-resistance' faults.
How do I test for a ground wire?
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
Where does earthing current go?
it takes the lowest resistance path back to the current source Answer: Earth leakage current flows down to earth through the consumer earth continuity conductor.
Why general mass of earth is good conductor?
because of the moisture in the ground.
What is a circuit connected to the Earth called?
Grounding?AnswerIf a line conductor is unintentionally connected to earth, then it is an earth fault.
Conductor directly connected to the earth?
A conductor that is directly connected to the earth is called ground. One of its applications is through the determination of the field strength of surface wave radio transmissions.

Is the ground an insulator?
The ground (earth if your Irish like me) is a protective conductor,in the event of a exposed conductive part of anything comes in contact with a current carrying conductor the earth dissipates the current to ground by a path of least resistance,ie a person would be harder to get through than a copper cable
When used on a copper based cable a continuity tester applies a small amount of what to each conductor?
