Grounding a metal electrical box is crucial for safety. First, ensure the power is turned off. Locate the green grounding screw inside the box. Attach a grounding wire to this screw, securing it tightly. Connect the other end of the wire to the grounding conductor in the circuit. If wiring a new fixture, ensure it has a dedicated grounding wire. Confirm all connections are secure. Finally, restore power and test for proper grounding using a circuit tester. These steps promote safety by preventing electrical hazards.
