Water Pump Ke Liye Kaunsa Wire Size Use Kare? (Full Guide)

 

Introduction

 

Ghar me water pump lagate waqt sabse bada doubt hota hai —
kaunsa wire lagaye taaki motor jale bhi nahi aur MCB trip bhi na kare

Zyada log motor ke HP pe dhyaan dete hain, lekin asli cheez hoti hai current (Ampere).
Galat wire size lagane se:

• Motor heat hoti hai

• Voltage drop hota hai

• Overload trip hota hai

• Winding jal sakti hai

Isliye pump ke hisaab se correct wire select karna bahut zaroori hai.

Pump ka Current kaise nikaale?

Formula:

Ampere = (HP × 746) ÷ Voltage

Single phase me approx formula use kar sakte ho:

1 HP ≈ 4 to 5 Ampere

 

Different HP Pump ke liye Wire Size Chart

Pump Power	Current	Wire Size
0.5 HP	2–3A	1.0 sqmm
1 HP	4–5A	1.5 sqmm
1.5 HP	6–8A	2.5 sqmm
2 HP	9–11A	4 sqmm
3 HP	13–15A	6 sqmm

👉 Ye copper wire ke liye hai

Distance ka bhi effect hota hai

Agar motor door hai (20 meter se zyada) to wire mota lena padega.

Example:

• 1 HP pump normally → 1.5 sqmm

• Door lagaya → 2.5 sqmm lena padega

 Isko bolte hain voltage drop problem

 

Galat Wire Size se kya problem hoti hai?

1. Motor garam hona

Patla wire current rokta hai → motor heat

2. MCB trip hona

Starting current zyada hota hai → breaker trip

3. Winding jalna

Low voltage = high current = winding damage

Kaunsa MCB use kare?

General rule:

	Pump                                               MCB 0.5 – 1 HP 10A 1 – 1.5 HP 16A 2 HP 20A 3 HP 25A Important Tips Aluminium wire mat lagao Joint kam rakho Earthing zaroor karo Starter/capacitor box dry jagah rakho Conclusion Water pump me sabse important cheez hoti hai sahi wire size. Thoda mehenga wire lene se motor saalon chalegi, warna baar-baar winding karani padegi. Isliye pump lagate waqt HP aur distance dono dekhkar wire select karo.
