In A.C systems, fuse is placed in phase-in order to
disconnect the circuit during faulty condition.
But, what is the reason for putting "LINK" in neutral
istead of connecting through (same) wire.

Answer Posted / suseendran
Phase will have voltage(potential) whereas neutral is
potential free.
Imagine
if a phase conductor(wire) gets cut and touches the earth.
Fault current flows thro it and fuses are required to
isolate the circuit.
Whereas if a neutral conductor gets cut and touches the
earth. Nothing will happen since it is potential free. So
fuses are not required.(Links are cheaper than fuses)
