Earthing is a fundamental safety measure in electrical systems that provides a low-resistance path for electric current to flow safely into the ground in case of a fault. Its primary role is to protect human life, electrical equipment, and property from electrical hazards. When an electrical appliance develops insulation failure or a live wire comes into unintended contact with a metallic body, the exposed metal can become live, creating a risk of electric shock. By connecting the metal parts of electrical equipment to the earth, earthing ensures that the excess current bypasses the human body and safely dissipates into the ground, reducing the chance of injury or fatality.
