Hence it is always advisable to test at electrical socket
with out connecting machine in the socket, that is there
willbe a 1-3 voltages should be in between neutral and
earth points.

Answer / puneet

earthing we can check by measuring the voltage betwwen phase and machine earth point if we get the voltage then it is ok

Answer / avi gulia

earthing can be checked by either checking voltage between the phase and earth or by checking voltage between the neutral and earth it should be 2 to 4 volts.
