And Oztrayleea.

Here one leg is 240, the other is neutral. The frequency is 50Hz.

The neural is earthed at one point in a domestic installation.

Some houses and industrial complexes have 3 phase power, which gives 3 lines 
at 415 volts each relative to each other. Each of the 415V lines is individually
240 Volts above earth. An exercise for the mathematicians is to explain how this
can be !!
