What do earthing systems do?

Earthing systems, also known as grounding systems, are crucial in electrical installations as they provide a safe path for fault currents to flow to the ground. When an electrical fault occurs, such as a short circuit or equipment failure, excess current needs a safe route to prevent hazards such as electric shock or fire. The earthing system minimizes these risks by directing dangerous fault currents safely into the ground.

This is essential for protection of both people and equipment. By allowing fault currents to be safely dissipated, earthing systems also help to stabilize voltage levels in the electrical system and reduce the risk of damage to equipment due to electrical disturbances. In summary, the primary purpose of earthing systems is to ensure safety by providing a reliable pathway for fault currents, thereby protecting users and infrastructure from electrical hazards.
