Answer Posted / vinod sharma
In a three phase system p=1.732x3xVxIxCOS@
When load is given 50KW
Then I=50000/1.732x3x415x.8
=86A near about
taking some future expectancy you can take a cable of
having 100A capacity.SO by this u can take a cable of 70mm
square in aluminium and 50 mm square in copper
