I nikalne ke liye I use nahi karte.
Magar breaker size kaise select kare ye samajh nahi aya.

[@electricalstar7]

Dear Bhupendra Breaker size select karne k liye sabse pehle current ka value find karenge ...fir us current k value se Thora jayda value lenge breaker ka jo standard size ka breaker aata hai...
Jaise agar 25A current nikale to isse thora jayda breaker rating aata hai 32A
To Breaker size 32A hua
