What is purpose of earthing
Answered By: Adam Rivera Date: created: Jan 29 2022
Earthing is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth. It also causes the protective device (either a circuit-breaker or fuse) to switch off the electric current to the circuit that has the fault.

What is the difference between earthing and grounding
Answered By: Fred Carter Date: created: Jun 17 2022
The key difference between earthing and grounding is that the term “Earthing” means that the circuit is physically connected to the ground which is Zero Volt Potential to the Ground (Earth). Whereas in “Grounding” the circuit is not physically connected to ground, but its potential is zero with respect to other points.

How does PME earthing work
Answered By: Jesse Gonzalez Date: created: Feb 21 2022
The great virtue of the PME system is that neutral is bonded to earth so that a phase to earth fault is automatically a phase to neutral fault. The earth-fault loop impedance will then be low, resulting in a high value of fault current which will operate the protective device quickly.
