Earthing is a fundamental safety measure in electrical systems, designed to protect both personnel and equipment from the hazards of electric shock and fire. It provides a low-resistance path for fault currents, ensuring that any leakage or abnormal current flows directly to the ground rather than through a human body or sensitive equipment. In mechanical and electrical installations, proper earthing helps maintain the potential of exposed metallic parts at ground level, minimizing the risk of electrocution during insulation failure or accidental contact with live conductors. By connecting the metallic frames of machines, switchgear, and other electrical equipment to the earth, earthing also stabilizes the voltage during
