Answer Posted / ramesh kumar k
the size of the cable depends upon the material used in the
cable...
if u go for copper cable... the copper has got the current
carrying capacity of 2A/sq.mm continuously with out
overloading effect. so if you want for 550A,
550/2 = 225 sq.mm copper cable u have to use...
i think it is 1.2A/sq.mm for Aluminium...
550/1.2 = 458 sq.mm Aluminium cable u have to use...
like this.... the current carrying capacity is different
for different materials...
