How can we determine or find out the proper size of any
cable if nothing is mentioned on it.Calculation of size in
Sq.mm???
Answer Posted / girish
measure dia of cable in mm by scale suppose n
area of cross section of cable = n e2
if 20 mm is dia of cable means
area of cross section = 20 x 20 = 40 sqmm
Note: but you should measure only conductor dia not
insulation included in that
