Question

What is functions of earthing?

Answer 1

✌️✌️ hey mate,

➡️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.

thanks...
nice to help you ✌️✌️

Answer 2

In an electrical installation, an earthing system or grounding system connects specific parts of that installation with the Earth's conductive surface for safety and functional purposes. The point of reference is the Earth's conductive surface. The choice of earthing system can affect the safety and electromagnetic compatibility of the installation. Regulations for earthing systems vary considerably among countries, though many follow the recommendations of the International Electrotechnical Commission. Regulations may identify special cases for earthing in mines, in patient care areas, or in hazardous areas of industrial plants.
