The most helpful thing you can do when figuring out 120 and 240 is to totally forget that the neutral is grounded. The neutral is grounded for other reasons that have nothing to do with the voltage that you read on it. [The word 'neutral' used for clarity of communication with the intended audience, and is not the technically accurate term]

240 volts is derived from the two outermost taps on the utility transformer. The neutral conductors is the midway or halfway tap on the utility transformer. With some hesitation, I made this drawing, in case it helps. You can see that whether you're using 120 volts or 240 volts, there is a "circle", "ciruit", or complete path from the transformer back to the transformer.

Cookie,
Three phase?
Now you have to get into delta and wye configurations. Then we are going to throw in the wild leg on the wye config!

You need to push with two hands and kick with 1 foot. However with the wild leg, you have to kick even harder!
