why we generally use 3.5 core cable or in other word 1/2
core for neutral and also confirm me that in balance
conditiob(3 phase)current in neutral will zero

Answer Posted / sangekar vaijnath
Generally it depend on load, If cable is used for inductive
load e.g.motor, if there is any fault then 1/2 core is
sufficient to carry fault current due to lagging power
factor. However, in resistive load we are using 4 core
cable since there is no power factor.
