Earthing and earth leakage protection devices play a crucial role in electrical safety management by preventing accidents that may result from electric shocks, equipment damage, or fire hazards. In any electrical system, safety depends on proper control of fault currents and the maintenance of low potential differences between exposed conductive parts and the ground. Earthing and protective devices work together to create a safe path for fault currents and disconnect dangerous circuits before they can cause harm to people or damage to property. Earthing, also called grounding, refers to the direct electrical connection of metallic parts of equipment and installations to the earth. The purpose of earthing is to maintain all exposed metal surfaces of electrical appliances at earth potential so that in case of insulation failure or leakage, dangerous voltages do not appear on these surfaces. Without earthing, if a live conductor accidentally touches the metallic body of equipment, the body becomes energized and poses a high risk of
