I think this question is appropriate here in order to help DIYers (me) to understand why a neutral isn't needed on a 240 volt outlet.
I understand that two 120 volt power sources that are 180 degrees out of phase can be combined to provide 240 volts and I believe they accomplish this by using each others off phase to complete the circuit.
My Question
If all AC electrical power completes its circuit by returning to earth, how is that accomplished in a 240 volt circuit with no neutral?
