If the compressor were rate for 120V instead, one "line" would be L1, and the other "line" would be Neutral, "N", because it's connected to the center tap at the transformer, but for all practical purposes nothing has changed except the voltage.

Don't get hung up on the term "neutral". It's a power wire just like L1 is. It brings power into the run cap just like L1 does. Power comes in thru L1 and leaves thru N, and it also comes in on N and leaves thru L1, alternating back and forth.

Thank you very much. I never really had a thought l1 and l2 had a relevant difference in voltage or function of each other, but I needed to ask. But, y'all have pretty much cleared up the differences between 'hot' and 'neutral'.

Because of that small lesson alone I'm able to read pretty much any circuit in my book now.

3. Great!

The ENTIRE circuit has current movement when energized, and the ENTIRE circuit loses current movement when de-energized.
If you believe that, design your metallic lamp with the power switch on L1 and then touch your lamp. You will learn that only part of your circuit has current... o.O

Switches always go on the neutral side.

Well feel free to delete all of this. It isn't very helpful. Remember kids, switches and fuses go on L1, the hot side.
