⚡ Master Your Home Wiring: Complete Switch Board Connection Guide! 🏠💡
Ever wondered how the messy wires behind your switchboard actually work? Here is a simplified breakdown of two very common household connections.
Save this diagram for your next DIY project or electrical study! 👇
📋 Image Breakdown:
1️⃣ Top Diagram: 3 Switches + 3 Sockets
This setup is commonly used for extension boards or power strips.
🔴 Red Wire (Phase/Line): Connects to the bottom terminal of all switches. This carries the current.
⚫ Black Wire (Neutral): Connects directly to the 'N' terminal of all sockets.
🟢 Green Wire (Earthing): Connects to the top (thick) pin of the sockets for safety.
** The Logic:** When you flip a switch, the current flows from the top of the switch into the 'L' terminal of the socket.
2️⃣ Bottom Diagram: 3 Switches + 2 Sockets + 1 Bulb Holder
This is a standard room board layout where you need to control a light bulb along with plug points.
Switch 1 & 2: Control the two sockets.
Switch 3: Controls the Bulb Holder (Light).
Note: The Neutral wire (Black) is shared between the sockets and the bulb holder to complete the circuit.
⚠️ SAFETY FIRST: Always switch off the Main Power Supply (MCB) before touching any wires. If you are unsure, always consult a professional electrician.
