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 the ground, but its potential is zero with respect to other points.

What is the Difference between Earthing and Grounding?
Earthing:
Earthing can simply be defined as the process of protecting against unwarranted spikes and bouts of electricity that can cause damage to life and property. Therefore it is important to remember these key differences between the two. One needs to understand that they both are referring to the same process.
Grounding:
Grounding is similar to Earthing, which achieves insulation against accidental currents. The main live wire is connected to a power supply to power an appliance. However, the other portion of the wire is led under the earth. This is done in case of an accidental cut in the circuit to avoid overloading and other dangerous side effects.
Earthing VS Grounding

| This method protects human beings from electric shocks. | This method protects the entire power system from malfunctioning. |
| The earth wire used is green in colour. | The wire used for grounding is black in colour |
| Earthing is primarily used to avoid electric shocks. | Grounding is primarily used for unbalancing when the electric system overloads. |
| Earthing is located under the earth pit, between the equipment body and the underground pit. | It is located between the neutral of the equipment being used and the ground. |
