Step-by-Step Installation Guide:

Preparation and Safety:

Before beginning, turn off the main power supply at the consumer unit and ensure the area is safe to work in.
Use a voltage tester to confirm that there is no power running through the circuit you will be working on.
Remove the Old Consumer Unit (if replacing an existing unit):

Disconnect all circuit wires from the old consumer unit.
Unscrew and remove the old unit from the wall or mounting board.
Mounting the Lewden Consumer Unit:

Position the new Lewden consumer unit on the wall or mounting board.
Mark the drilling points, drill holes, and secure the unit in place with appropriate screws.
Wiring the RCBO Board:

Strip the insulation off the ends of the incoming main supply cables.
Connect the live (brown or red) and neutral (blue or black) wires to the main switch terminals inside the consumer unit.
Secure the earth wire (green/yellow) to the earth bar in the unit.
Install the RCBOs (Residual Current Circuit Breaker with Overcurrent protection) in the allocated slots on the consumer unit.
Connecting Circuit Wires:

Connect the circuit wires to their corresponding RCBOs, ensuring tight and secure connections.
Each RCBO will typically have live, neutral, and earth connections. Follow the manufacturer's wiring diagram for precise connections.
Testing the Installation:

After all connections are made, double-check for tightness and accuracy.
Turn the main power back on and use a voltage tester to ensure that all circuits are correctly energized.
Test each RCBO by pressing the test button to ensure they trip and reset correctly.
Finishing Up:

Neatly organize and secure any loose wires with cable clips.
Replace any covers or panels on the consumer unit and screw them in place securely.
Label the circuits on the consumer unit for easy identification.
Final Checks:

Perform a final inspection to ensure all connections are secure and there are no exposed wires.
Confirm that all safety measures are in place and that the consumer unit is functioning correctly.
