Answer Posted / javed butt
At starting point(generator output) ref circuit is called
neutral. When we use phase & neutral in a circuit(2 wires
only) and connect same neutral wire with case as a ground,
it will work. But if phase and neutral and enterchanged,
then case will become hot and will be dangrous for the
humen life. When a separate earth wire is connected to
neutral at generator's out put and earth wire is run
separately and connected to the case, it will remain ground
even if the supply (2)wires are interchanged. In case of
leakage (hot to the ground) it will blow fuses and protect
the humen life.
