Answer Posted / bhatt
current carrying capacity of conductor depends on many
factors,
size, shape and material of the conductor, ambient
temperature, insulation and laying method:
As area of the conductor increases current density is
decreasing hence 2.5 times per sqmm. for coer and 1.5 times
per sq.mm may be alright for smaler size conductor but at
400 sq.mm. it may be only around one time as perimeter and
area also affect the current carrying capacity.
