Advice on wiring run, please
I am installing a bathroom in the corner of a 20' X 20' finished room. I have a more than adequate size subpanel in the room, and it is located about 15' away from where I need to run new cables to. The room has a cathedral ceiling and a concrete slab floor, so I have no basement or attic to run cable through.
The run would be along a single, exterior wall. If I have to tear out 15' of sheetrock horizontally, I will, but I'm also wondering if it is code compliant to do the following:
1. Run the cables inside the wall from the subpanel down to near floor level, and then take them to the exterior of the wall through a conduit body.
2. Run them from the conduit body through 15' of conduit on the outside of the wall,
3. Then bring them back inside the wall through a second conduit body.
The three cables I need to run are two 8/2 and one 12/2, both NM-B.
Any advice, besides whether this is code-compliant, will be welcomed. Thanks.
