As the title says, I need to move (per my new load calcs after changes were made) three of the bottom breakers on the left panel, over to the right panel. However, the wires do not have enough slack to move them over. Even though it may not seem like it at first glance, the panel on the right has room to move them while staying within the 80% rule on both panels. The amp loads on the double pole breakers on the right are much smaller than the ones on the left. Likewise, the loads on the single poles are minimal as well.
The wires that need to be moved are all 8/2. The only thing I can think of that would work is mounting the junction box(s) to the outside of those middle studs. There is less than 4-6" of space between the spray foam and the back of the studs. Is there any other solution I am overlooking? Also, is there anything that would be against code in my plan? If everything is otherwise ok per code, would you recommend one very large junction box (I like to give myself lots of extra room when splicing 6-8awg) or smaller, individual junction boxes for each separate run? My only concern is that aesthetically, the large junction boxes mounted to the outside of the middle studs would look a little ridiculous, but I'm not sure what the alternative is. This isn't to say the wiring above doesn't look ridiculous, but here I am.
P.S. Yes, my friend who originally did all those 10/2 on the left and right panels over 2 years ago should have had them come in at 90 degrees. The inspector noted as much but otherwise said it was fine. I had done all the terminations and path through the attic, and left it up to him to finish the runs to the panel. If I had it to do over, I would have finished it myself.
