Earthing a metal back box is crucial for safety. First, ensure the power is off. Locate the earthing terminal in the back box. Use a piece of earth wire, which should be the same gauge as the circuit conductors. Connect one end to the earthing terminal using a green/yellow sleeve for insulation. The other end connects to the circuit’s earth wire. Screw the connections tightly. Check all connections are secure before restoring power. This provides a pathway for fault currents, ensuring safety. Always consult a qualified electrician if unsure.
