Initially, I'm going to be plugged into basic 120v from an outlet.
However, I'll be moving in a year, and want to be able to plug into 240v if available.
How to achieve this flexibility in the subpanel? I'll need two outlets obviously, but will I need to just rewire the input to the main breaker when I switch between 120v and 240v?
Also, I bought a Homeline 100A main panel. However, the main 100A breaker it came with is setup for double pole. How do I connect 120v, 8-2 to this safely? Do I just have to connect to one side only with the one hot line and leave the other side non-functional?
