To find the cable size:
1.Decide the load ratings ie., voltage, FL current of the
load.
2.So that P = V*I*PF
3.Now apply ohms law, V=IR.
4.Now we have the resistance, as per the resistance we can
choose the cable. R= (permeability*Length)/Area of C.S

If the maximum demand is 120 KVA in a building, then what is the Current taken according to load given ? Formula for it ?
