Answer / k.prakashchandra

carrying capacity for cu cable is taken as 2.5 A and 1.5
for Al, per sq mm.In case of generator as the load is
continuous at full value ,they are taken as 1.5 and 1

Answer / mujeeb

as cureent is directly prop to cable size
so if the size of the cable of the is in c then current
carrying capacity of the cable also inc ......
so if the loaD is know then cable size can be easily
determined

Answer / hareesh k.s.

depends nature of load.if load is motor cable should
withstand high starting current.

Answer / p.parthasaradhy

Normally, the cable manufacturer will provide the cuurent
carrying capacity of a cable. As the cable size increases,
the current density per sq.mm. will be reducing. Also, based
on the distance between the cables during the layout in the
duct the multiplying factor changes ( less than one). the
loading is more for an underground cable is more as compared
when the cable is laid above the ground.
