What is the difference between earthing and grounding?

Question

Accepted Answer

Earthing and grounding are terms used interchangeably, but they have different meanings and applications.

Earthing refers to the process of connecting electrical systems to the ground to prevent electric shock and protect against lightning strikes.
Grounding, on the other hand, involves creating a low-resistance path between an electrical circuit and the earth to ensure proper functioning and safety.
Earthing is primarily concerned with safety, while grounding focuses on electrical performance and stability.
Earthing is commonly used in residential and commercial buildings to protect occupants from electrical faults.
Grounding is essential in electrical systems to prevent voltage fluctuations, reduce electromagnetic interference, and provide a reference point for voltage measurements.
For example, a lightning rod is an earthing system that protects a building by providing a path for lightning to safely discharge into the ground.
In contrast, grounding a power distribution system involves connecting the neutral conductor to the earth to maintain a stable voltage reference.

Accepted Answer

There are two types of earthing Copper required for neutral in DG and transformer and GI earthing is required for body earthing.
