I am looking at running a sub-panel, 100 amp, into my garage. The main panel is on the outside wall of the garage. I was thinking of putting the sub-panel right next to the main panel only on the inside of the garage wall. I was going to mount the panel in between the studs and then drill though the one stud that is between the panels and run the appropriate wiring through the hole. From the sub-panel I am going to run 110 and 220 to 4 different locations in the garage through conduit. I am going to get a permit for this work. Some other electrical was run a few years ago and I am going to include it in the permit process. The city adds $35 to the permit for work that was allready completed. I will draw out everything before i go to get the permit. I am trying to find out if the location of th sub-panel is OK.
