The main purpose of earthing electrical circuits is to provide a low-impedance route back to the substation transformer which, in the event of an earth-fault will allow sufficient fault current to flow in order to operate a circuit's overcurrent protection.

What is the connection between any electrical circuit and the earth is called?
Electrical circuits are grounded to the earth.
What is the difference of earth and insulated return in an electrical system?
An earthing system is a system where circuits are connected by a ground. An insulated return system is how power is transferred to trains.
What has a stream of charged particles coming out of the sun that can disrupt communications and electrical circuits on Earth are known as?
A Solar Flare .
Why is a metal wire connected from an aircraft to the earth during refuelling?
This grounds the aircraft and protects it from any electrical disparity.
Is the age for Paranormal Activity changing?
Paranormal axidents has hapend since we humans stand on earth
What is earthgrounding wire?
Earth wire (or earth grounding wire) is a safety system which helps prevent electric shocks. It is connected to the electrical cable of an appliance.The earth wire connects the metal frame of the electrical appliances to the ground. The convention is to have green colour for earth wires. The purpose of earthing is that in case of an insulation failure in some appliance, this wire connected to the metal body will provide a path for the current to flow on the ground. In absence of earth wire, this fault current would have flown through the body of the operator, causing electrical shock.
What is the advantage of connecting the outer conductor of a coaxial cable to ground?
To prevent the outer conductor, or shield, from radiating, it is connected to electrical ground, keeping it at a constant potential.
What is the function of neutral in electrical system?
See related link. The neutral wire provides the electric current a return path back to the electrical generation system. It is connected to earth ground, and should have no electric potential in relation to earth ground.
How is an apple connected to the earth?

When was Connected Earth created?
Connected Earth was created in 2001.
How are the earth systems connected?
we are all connected through earth's
How do fuses and circuits breekers help to protect us?
Fuses and Circuit Breakers act as a control mechanism to the flow of current in electrical circuits. A fault can develop in an electrical appliance without us noticing and this is where circuit breakers and fuses help in automatically disconnecting the faulty appliance from the power source. Most electrical faults resulting excess heat generation which in turn cause fires. Electrical shock can also be prevented by special types f circuit breakers called Earth Leakage Circuit breakers (ELCB). These breakers operate whenever there is an earth leakage protecting humans.
