A) Firstly we have to check for wht type of system we require the cable i.e LV, MV, HV AND EHV
B) then we have to calculate first: the rated current required by load on 3phase or 1phase system i.e
1) For 3-Phase System
KVA= KW/SQRT3*PF
2) For 1-Phase System
KVA=KW/PF
C) In companies there is feeder schedule for every type of cable w.r.t the amp.
Enjoy!
