How to Wire a CCU for Power and Cooker Circuits

Image
 Wiring a Consumer Control Unit (CCU) is one of the most crucial steps in any domestic or commercial electrical installation. A well-wired CCU ensures that all loads are safely protected and separated for easy management and fault detection. In this guide, we’ll walk through how to wire a CCU to support both power sockets and a dedicated cooker circuit. Materials and Tools Required - Consumer Control Unit (double pole) - Miniature Circuit Breakers (MCBs):   - 1 × 32A for cooker   - 1 × 20A for power sockets   - 1 × 63A DP Main Switch - 6mm² cable for cooker - 2.5mm² cable for socket circuit - 10mm² Earth wire (if TT system) - Screwdriver set - Wire stripper - Test meter - PVC conduit or trunking - Proper earthing and bonding conductors Step-by-Step Wiring Process Isolate the Supply Before doing anything, isolate the mains supply to ensure safety. Confirm using a voltage tester that the CCU is not live. Mount the CCU Secure the CCU on a plywood board or wall surface u...

Light bulb replacement

 How to Replace a Light Bulb – Step-by-Step Guide

⚠️ Safety First!

Before replacing a bulb:

- Switch off the light switch and the main power if necessary.

- Allow the bulb to cool down if it was recently on.

- Use a sturdy ladder if the bulb is out of reach.

🛠️ Tools and Materials Needed:

- Replacement bulb (correct wattage and type)

- Ladder or step stool

- Cloth or gloves (optional for handling hot or broken bulbs)

🔧 Step-by-Step Bulb Replacement Procedure

1. Turn Off Power

Switch off the light at the wall. If you're replacing a ceiling or high-voltage bulb, turn off the main breaker for extra safety.

2. Let the Bulb Cool

Wait a few minutes to avoid burns if the bulb was just on.

3. Remove the Old Bulb

For screw-type bulbs, turn counter-clockwise. For bayonet-type, push in gently and twist. Use gloves if the bulb is hot or broken.

4. Install the New Bulb

Insert the new bulb carefully:

  - For screw-type, twist clockwise until snug.

  - For bayonet-type, push in and twist into place.

5. Test the New Bulb

Turn the power back on and flip the switch to ensure the bulb is working properly.

✅ Final Tips

- Use the correct wattage to avoid overheating.

- If the bulb keeps blowing, there may be a wiring fault – contact a qualified electrician.

Ring circuit for socket outlets.

Image
Introduction A ring circuit is a wiring technique used in many countries (like the UK and Kenya) to power sockets efficiently. It allows current to flow in both directions around a loop, minimizing voltage drop and balancing the load. Tools and Materials Needed • Twin and earth cable (usually 2.5mm² for sockets) • 13A switched sockets • Back boxes • Screwdrivers • Wire strippers • Continuity tester or multimeter • Circuit breaker (typically 32A MCB) Basic Ring Circuit Connection Layout The consumer unit (CU) supplies power to the first socket. Each socket is wired in sequence until the last socket, which is then connected back to the CCU, forming a complete ring. Steps to Connect Ring Circuit to Sockets 1. Start at the Consumer Unit (CCU): Use a 32A MCB and run a twin & earth cable (live, neutral, earth). 2. Connect to the First Socket: Live to L, Neutral to N, Earth to Earth terminal. 3. Run a Second Cable to Next Socket: Continue to second socket and connect same terminals. 4. ...
