Answer / saad

one ton = 1250 watts
20 * 1250 = 25KW
P = 1.732 * V *I * Caso
25000=1.732*415*I*0.8
I=43.47Amps

Answer / rajatsahu

1 ton=3516 watt
20 ton=3516*20=70320watt
p=1.732*415*i*0.8
70320=575.02*i
i=

Answer / asif

One Toe = 3.5 kw

20 * 3.5 = 70 kw

P = 1.732 * v * I * cos0

70000 = 1.732 * 415 * I * 0.8

I = 122 A
