    I'd run the generator at 120v to both, unless you have 240v loads.  

    The generator wouldn't be loaded that much, so not a big deal, but running 240 limits capacity to 1/2 per leg, and could be an issue if one leg was loaded much more than the other.

    I have mine wired for 120v even though I now have a 240v pump.  I figured it was better to use an autoformer for the pump rather than deal with the leg load issues.

    Here is my final video with shoutout to NAWS at the end.  My system isn't really done but I want to move on to other topics as far as the videos are concerned.
