1. Turn Off Main Power: Before any work, switch off the main breaker to disconnect the entire distribution box from the electrical supply. This ensures that no current flows through the circuits during maintenance or removal . 2. Verify Power is Off: Use a voltage tester or multimeter to confirm that all circuits, including phase and neutral wires, are completely de-energized. This step is crucial to avoid residual current hazards . 3. Use Personal Protective Equipment (PPE): Wear insulated gloves, safety goggles, and rubber-soled shoes to protect against electric shock or arc flash injuries . 4. Access the Distribution Box: Remove the front cover using a screwdriver to expose the internal wiring and circuit breakers . 5. Disconnect Circuits:
