Current carrying capacity depends upon type of conductor and size&resistance &length of the conductor.
Eg:
Resistance of conductor is inversely proportional to cross section area of conductor and directly proportional to length of the conductor.
35 sq.mm cu cable can carry 130 amp
Current carrying capacity of cupper conductor is equal to 1.6 times of alluminium conductor in size.
4 sq.mm cu cable= 6 sw.mm am cable
