Earth is an electrical conductor solidly connected to a
grounded peg or typically to a galvanised steel water pipe.
Neutral is a connecter to the star point of a three phase
power supply where all three phases are joined. If the three
phase load is balanced, there will be no current flowing in
the neutral conductor. The neutral conductor runs from the
appliance to the neutral point of the supply transformer.
Earth leakage protection devices monitor the current flow
from the Neutral conductor to earth though an earth leakage
detector device. If a leakage current is detected, it
indicates a faulty, and therefor a dangerous situation. The
earth leakage device will trip the mains as a safety precaution
