When testing an earthing connection, we use a 60 or 100 candle bulb with a phase connected direct from supply and the other wire to the new earthing provided.If the bulb glows then the earth is ok.Else earth connection is not Ok. So, why dont we can use all the home appliances taking a single wire from the phase and the return connection to Earth instead of return connection to neutral?
