I am planning to add an outlet circuit to my garage. Strangely, when they built the house, they only put two outlets in the entire garage, both of which are on shared circuits with the rooms on the other side of the wall (living room and kitchen). I have more than 100 feet of 12-2 Romex left over from other wiring projects, and wanted to know what my options were for using it in a surface mount application. I really don't want to open the walls up in the garage. Quick research indicates that it's NOT against code to run Romex in conduit, but it's not best practice for heat dissipation purposes and can be a pain to pull. I know THHN is relatively cheap, but not if I need to buy 3 separately colored spools of it rather than buying one larger spool and remarking the wires (which is against code, correct?)
Thanks,
