Earth and Ground are the same. But the neutral is different from the former two. As the neutral is the star point where one terminal of each of the3 phases are brought together. In balanced voltages3 phase supply the neutral voltage should be zero.

But in some electrical network configurations - namely IT-S configuration, the earth and neutral are the same and is symbolized by PEN or EN.
