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)

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
