Auto Start Water Tank Motor Connection ghar me kaafi useful hota hai. Ye system tab motor ON karta hai jab tanki me paani kam ho jaye aur tank full hote hi motor automatically OFF ho jata hai.

⚡ Auto Start Water Tank Motor Wiring (Full Info)
🔹 Components Required:
1. Single Phase Motor (Pump) – Jo paani fill kare.
2. Float Switch / Water Level Sensor – Tank ke andar lagta hai (paani ke level ko detect karta hai).
3. Contactor / Relay – Motor ko ON/OFF karne ke liye.
4. MCB / Switch – Overload protection ke liye.
5. Wires + Earthing – Proper connection ke liye.

🔹 Working Principle (Kaise Kaam Karta Hai)
1. Jab Tank Khali ho – Float switch contact close ho jata hai → Contactor energize hota hai → Motor start ho jata hai → Tank fill hona shuru.
2. Jab Tank Full ho jaye – Float switch contact open ho jata hai → Contactor de-energize ho jata hai → Motor automatically band ho jata hai.

🔹 Wiring Connection (Step by Step)
1. Phase (L) → MCB → Contactor → Motor ke Phase terminal.
2. Neutral (N) → Seedha Motor ke Neutral terminal.
3. Earth (E) → Motor body me connect karo.
4. Float Switch (Water Level Controller)
Float switch ko contactor coil circuit me series me lagate hai.
Matlab: Phase → Float Switch → Contactor Coil → Neutral.
Jab float ON karega tabhi contactor energize hoga aur motor chalegi.

🔹 Safety Points
Motor ke liye Overload Relay (OLR) use karo.
Tank ke andar high level + low level float switch dono use karo to system perfect kaam karega.
Wiring hamesha 3 core wire (Phase + Neutral + Earth) se karo.

✅ Simple Logic:
Low Level Float = Motor start.
High Level Float = Motor stop.
