We use Fuse for over current but neutral use
for complete the circuit.
If we applied no problem.
But in case of fault it will be difficult to get fault
easily.

if we look on phasor of the transformer vaoltage is 180 oppsite at primary and the secondary so to improve a power factor is secondary should kept negative to improve it primary side means is -.90 became +.90 at other side
