🔌 Single Phase AC Wiring (हिंदी + English)
1. Supply Connection (सप्लाई कनेक्शन)
Bijli board se ghar me 2 wires aati hain – Phase (L / Live) aur Neutral (N).
Ek alag wire hota hai Earth (E) jo safety ke liye lagta hai.
---
2. Main Distribution Board (MDB / DB)
Phase wire (L) → MCB (Miniature Circuit Breaker) ke input me jata hai.
Neutral (N) → Neutral busbar me connect hota hai.
Earth (E) → Earth busbar me connect hota hai.
---
3. Load Connection (Fan, Light, Socket, AC etc.)
Phase (L) → Switch → Load (Fan/Light/AC).
Neutral (N) → Direct load ke dusre terminal me.
Earth (E) → Load ki metallic body ya Socket ke earth point me.
---
4. Safety Rules (सुरक्षा नियम)
Har alag circuit ke liye alag MCB use karo.
Heavy load jaise AC, Geyser, Refrigerator ke liye Alag line + Proper earthing lagao.
MCB + ELCB/RCCB use karna chahiye shock protection ke liye.

✅ Example: Fan/Light Wiring
Phase → Switch → Fan/Light → Neutral
Earth → Fan/Light body
