Neutral conductor must be 1/2 the size of other
conductor.It is theoraticaly expalin that algebric sum of
all the phases when in balannce condition then neutral
current will be zero.
Now suppose one phase fail i.e total unbalace condition its
neutral conductor will provide a return path and its
current will be half the load on other phases.so by this
result on neutral conductor for every unbalance condition
its current will not exceed the rated than other phases.
