Electrical grounding, also known as earthing, is a critical safety measure in electrical systems. It involves connecting specific parts of a building, such as metal pipes and structural steel, to the earth to prevent electric shock and fire hazards during electrical faults. Ground wires, typically thick copper cables, link metal components to a grounding block and then to the main earthing cable, ensuring a low-resistance path for fault currents. In some cases, ground rods—copper-coated metal rods inserted into the ground—are used to establish this connection, especially in rural areas lacking an earth provided by the electricity distributor. Proper grounding ensures that in the event of a fault, electrical current is safely directed into the earth, reducing the risk of injury or damage.
