Why link is provided in neutral of an ac circuit and fuse in phase of ac circuit?






Neutral is the return path for current in an electrical circuit. So if you put a fuse on the neutral and link on the phase, then your equipment will burn before neutral fuse burn. That means no use and there won't be any protection for the equipment but you can use fuse on both if you want.but you are increasing the chance of circuit incompletion because in any case if neutral fuse disconnected you will lose the circuit. So no need of a fuse in the neutral.
