New here, house built in 1971, bought last year. Rewired in 2007. New main panel where old panel was. New panel enters through crawl space via conduit whereas old panel entered through outside wall. Newer dryer wire 10-2 run through conduit through crawlspace. Want to run 10-3 to new dryer location. Conduit through crawlspace appears full. Can I run 10-3 through wall where old lines run instead of through conduit?
