I am trying to add a 30 amp service for my garage-parked RV. I have plenty of open slots in the electrical panel (which is mounted midway on the wall in my garage) and the plan was to do a 2.5 foot run straight below to a single 30amp plug. Do I need to shield the cable if it is inside the wall or will a simple hang between the studs suffice? The garage is prefinished so I was hoping to just make a hole for the after build box and run the cable straight up. Thoughts or suggestions?

  • "Thoughts or suggestions" questions are usually too broad here. I've revised your title to be more specific. Please see How to Ask and take the tour.

  • "After build box"? Does that mean you have drywall or some other interior sheathing?

  • I answered or started prior to the edit is this a finished wall that will be cut? If so the cable will need to be covered.

Code requires the cable through the studs below 8’ to be covered.

In the past we have cut a sheet of Sheetrock in strips to cover the Romex (what we used). Plywood would have been better but on these jobs the owner wanted CHEEP!

4 strips per sheet attached was all it took to pass inspections no cap on the top but I have heard of a cap being required.

Code only states 1/2” Sheetrock or plywood not the entire wall, we also did the same above and below the service panel as required.

  • If the hole is along the stud yes by code it needs to be covered.

  • That is ugly. I don't know how you put up with customers like that. I guess their house their rules. Aug 2 at 23:43
  • It may be ugly but many homes prior to the requirement had nothing in the garages and this was in the late 70’s when those homes were 1/2 million don’t know what what they are worth today but many times more ugly or not it met code

The plain cable should be okay inside the wall, the mounting/attachment requirements should be waive inside a finish wall. you don't need to attach to wall. This is for the cable.

I believe any plugs in a garage need to have GFCI protection, probably a breaker type, since I don't know if they have 30 amp GFCI plugs/receptacles.

Conduit is extra protection, since mice/rats don't usually eat conduit. They do like cables.
