Good info, and Golfish was right you don't want to exceed 80% on a circuit...I have the 4 dedicated 20amp circuits for my fishroom...You never have enough outlets it seems and then you don't want to overload anything. The additional outlets or lines won't be a problem down the road if you sell your house if it's done properly. Make sure your lines are run without major kinks or bends, secure all wiring if possible and I even took the extra time to fish the lines down through the drywall, and a big thing is make sure your connections on the outlets and switches are done correctly and tight. An electrician will rip it apart if the connections are done poorly.....
