Answer / avd

It is basicaly for safety and easy diagnostic purpose. If
neutral fuse is provided, it will blow during fault but
phase supply will be available at fault point which may be
harmful during checking.

Answer / maria joeshua prabu

In electrical circuit there is a two path one is live throw
path,and another is live return path (or clossing
path).when we are getting more load , any short and
maintenance in electrical circuit, it has tobe isolate the
power,which is in the live path,no use to isolate the live
return path.

Answer / bk

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.

Answer / manisand1

Because the complete circuit is used in neutral link and if
we use fuse or other interrupting device this may block the
returning of current and the live conductors will not be
isolate.

Suppose a 3 phase, 2 pole, 440V induction motor is driving a flywheel of 600mm diameter, 150kg mass. By using v-belt and pulley, the speed is increased to 4500 RPM. What will be the effect on motor current?
