I'm still working on running electric out to the shed/barn/workshop. Max electrical draw will be from a fridge/freezer, TV, Lights, small AC unit, and whatever tool I might I plug into the outlets like circular saw or router, bench grinder, etc. I've attached a picture of the box I got for free from my parents new install: major overkill for what I need. So, from people who know, would I be better off trying to find a smaller box and selling this to someone who needs it? I could pull the 20A breakers out as they would be useful, but 100A is just too much for my line out to the barn, so it would need to be replaced anyway. If I try to sell it, what's something like this worth?
