Neutral point is achieved by connecting common point of either two OR three diffrent phases of supply. However, earth is a zero potential point which is having solid connection with ground. Ther can be potential in neutral but earth point will always be at zero potential.

Answer / antu paul ekkan joseph

The value of potential(volts) for a balanced polyphase(eg. 3 phase system) is zero volts.But for unbalanced polyphase system the value depends on relative phase shift angle between phases.For single phase system neutral is the normal return path for the load current.But earth is supposed accidental bypassing path for the fault currents(eg. shortckt. current,leakage current,etc. etc..)It might be might not be a p.d b/w neutral and earth depends on the type of distribution system (single phase or poly phase),type of earthing system ie, TN,TNCS,TNS,IT,TT and its connections.

 earth is for only circuit protection.
And neutral is for voltage balance in circuit.
