Thank you so much for this explanation sir. But i dont know why you didnt use copper cable for feeder 3, but rather used aluminum. I will be so glad if you can explain to me 11:21
For three phase , P = √3 VI cos I = P/ √3 V cos √3 = 1.732 , V = 415 , cos = 0.8 If you multiple these three it will come 575 Similarly for single phase , without multiplying 1.732 .. You will get 184 for 215v . Hope you understand
1 sq mm Copper Cable Current Carrying Capacity: Copper cables with a cross-sectional area of 1 sq mm exhibit an impressive current carrying capacity of up to 30A, making them ideal components for electrical wiring
