The last house that I wired was a 400 amp service and they stole my panels (cut the wire just above the panels) and I contacted my local county inspecter and told him what I was planning to do. I took a smaller 100 amp panel and gutted it out and mounted it above the new panel and used this as a large junction box. I simply put connectors in the top and bottom and extended the wire. This was actually in the basement bu the covers that come with the small panels dont look to bad ( I just didn't remove any of the cover knock outs) Plassed with no problems
