I purchased a foreclosure that the previous owners took out some aggression on. They cut sections of all of the romex leaving the panel. I counted 8 circuits that need to be spliced. The panel is mounted on a finished wall and I only have about 2 inches of wire protruding. My thought is to remove some drywall around the area to expose 8 inches or so of romex. Attach some plywood to the wall then mount 8 boxes to it. I'd like to splice the wires (wire nuts) and run new romex into the panel and breakers. The question is, is this the best approach or is there something better or simpler. What a mess.
