Taking down my ceiling to run some wire to new outlets. The outlets are going in an area with an unfinished ceiling, so I know the romex there will need to be ran through the joists when going perpendicular, to get to its destination.
On the way to the breaker box though, it's going through a finished ceiling. In that portion of finished ceiling, I noticed someone basically took nails, turned them sideways, and used that to secure the romex (home made staple).
That got me thinking if I didn't have to bore through the joists in the finished area, and save me a ton of labor. I know the code is probably to prevent people from hanging stuff on the romex when it comes to unfinished ceilings, but still. I would use insulated staples instead of nails, but the concept is my question.
I also came across this on a separate site, but more confirmation doesn't hurt.
