to calculate the size of cable you have to follow the
following:-
FOR FEEDER
1- load rating
2- voltage rating
3- determine the full load current(IFL)
4- total deration factor to be found
5- determine the cable current carrying capacity=IFL/total
deration factor
6- above value to be comprise with the valu of current
carring capacity in the table of factory

need to make a report. Need to choose a 3phase induction motor.
