In a single phase system very often three wires are provided: 1.LIVE,2.NEUTRAL,3.EARTH.In the single phase system we have to prove a return path for current otherwise no current will flow...and that is the typical job done by the neutral wire i.e. it serves as a return path...On the other hand earth is provided for the purpose of protection,whenever a fault occurs in the system huge fault current which is many times the rated current flows through the earth wire and in thus way protects the system...
