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 / 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)

i am confused about generator. i have generator of 380 KVA that is 304 KW by that formula KW=KVA*0.8... then by this formula I=KW/V*1.732*0.8 the amperes are 528.673. so that is the load which i put on one phase of generator or this is total 3 phase load on Generator.......
