when we r using 3.5 cable for a bldg. and put laod on each
phase using the neutral and neutral is the return paht for
the phase so the current of the neutral must be Ir+Ib+iY
(return).But the size of the netural is .5 as comper to the
phase.

Answer Posted / saireen

3.5 c cable neutral is not the return path for the face but only that current which r unbalance among 3 phase, and that is sufficient to keep size 1\2 as compare to phase.
