I'm remodeling my fixer house, and I plan to install an electrical panel in an unfinished basement. At some point (hopefully in the near future), I'll finish the basement space. This will add thickness to the walls (insulation and framing).
If I want to move my panel from the unfinished wall to the finished wall, what's the proper/correct way to allow for the extra length of wiring I'll need to account for the change in depth (about 4-6")? I'm interested in both accounting for extra length in branch circuits as well as the feeder cables coming into my house. Citations of relevant sections of Code are appreciated.
