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...

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. ...
