Firstly the current flows through the phase wire and returns in neutral.if we connect the fuse in neutral it will burn after sh ckt, but the line lives in load(machine) so it will harmful
2nd- the magnitude of neutral cable is half 3 phase line where the unbalanced load(current) returns through neutral.
