Fuse is used for safety as well as the protection of the
equipment.When short circut occurs and if fuse is connected
to the neutral then fuse of neutral will be blown off, but
it is of no use because we are disconnecting the path that
is directly connected to the earth. Since our body is also
at ground and neutral is also grounded therefore if neutral
is not disconnected then it will not effect the safety,
because if someone touch the neutral(seperately} it will
not cause of shock wheather fuse is connected
Now if live supply is not disconnected it will cause shock
to the prson, since our live supply is not at ground
potential.
Therefore it is mendatory to connect fuse in live portion
and it is of no use to connect fuse in the neutral.Besides
of that during short circuit fault neutral will give return
path to the faulty current.
