Sorry, I didn't see you sneak in before. You must have posted while I was formulating my last reply.
There seems to me to be a gray area here, (to me anyway) as to what makes a room in a basement a habitable room and would them require minimum and proper wiring.
If I had a customer that was putting up walls in the basement for some purpose, would I automatically have to provide outlets spaced to code? Suppose He has a specific purpose in mind and a limited budget? Is it the construction or features of the room that make it "finished" or "Habitable" or is it the actual or intended usage?
I also feel that if there is an unfinished area adjacent to this room that it should have GFCI protection on receptacles. (not on lighting though)
Any facts or opinions on this?
