sir, i want to know the calculation for find rated current
for cable sizes.(both copper & aluminium) with examole.
please sir

for example: 35sq.mm al.cable is withstands for how many
amps?
is suitable for 45kw motor?

Answer Posted / k.prakashchandra

Generally, the current carrying capacity of copper cable is
taken as 2.5A/sq mm, and that of Al 1.5
