2)how far or the distance
3)what is the voltage
4)what type of conductor to be used.
5)have the cable manufacturers catalogue
deciding on the type of conductor example aluminum or
copper, armoured ,surface mounted or under ground and
knowing the expected load the voltage drop is calculated and
the most suitable cable size is selected which falls within
