| Wiring diagram for a single room |
Here’s a clear conceptual layout of a one-room, complete electrical wiring system with all the points and wires you mentioned. Since I can’t show you the actual diagram here, I’ll break it down in a structured way so you (or your technicians) can easily visualize or draft it:
⚡ One Room Complete Electrical Wiring Layout
🔌 Main Components
Switchboard: Central control point with switches, fuses/MCB, and sockets.
Light Point: Ceiling or wall-mounted lamp connected via switch.
Fan Point: Ceiling fan with regulator connected via switch.
Outlet Point: 3-pin socket for appliances.
Earthing Wire: Safety grounding connection.
Phase Wire (Live): Carries current from supply to load.
Neutral Wire: Returns current back to the supply.
🧩 Wiring Connections (Step by Step)
Incoming Supply
Phase (Red) and Neutral (Blue) wires enter the switchboard.
The earthing (Yellow/Green) wire also enters the switchboard and connects to the earth terminal.
Light Point
Phase wire → Switch → Light bulb holder.
Neutral wire → Directly to light bulb holder.
Earthing wire → Metallic body (if any).
Fan Point
Phase wire → Switch → Fan regulator → Fan motor.
Neutral wire → Directly to the fan motor.
Earthing wire → Fan body.
Outlet Point (3-pin socket)
Phase wire → Socket live terminal.
Neutral wire → Socket neutral terminal.
Earthing wire → Socket earth terminal.
Switchboard
Each switch controls one load (light, fan, outlet).
Phase wire is looped across switches, while neutral and earth are distributed directly to loads.
🎨 Color Coding (Standard Practice)
| Wire Type | Color (Common Standard) |
|---|---|
| Phase (Live) | 🔴 Red / Brown |
| Neutral | 🔵 Blue / Black |
| Earthing | 🟢 Green / Yellow-Green |
✅ Safety Notes
Always use an MCB (Miniature Circuit Breaker) for overload protection.
Ensure proper earthing to avoid electric shock.
Use standard wire gauge (e.g., 1.5 for lights, 2.5 for outlets).
Follow local electrical codes in Bangladesh for compliance.
👉 If you’re working on public education and guides, WAZIPOINT SYSTEM can also prepare a clean line diagram version of this (like a schematic with just symbols and wiring lines). That would be perfect for training manuals, safety guides, or branding visuals.
Would you like me to draft that simplified schematic version next, so you have both the technical explanation and a visual reference?
