romex cable through exposed ceiling joists

Is it OK to use romex cable in unfinished (no drywall) garage ceiling, for example, for light fixture and garage door opener. Or should conduit be used.
I know that wiring in an unfinished wall needs protection but I am not sure about ceiling? (I am looking at an existing condition in my garage and wondering if it should be re-done, or protection added?).

Thumbs up

Nonmetallic sheathed cable (Romex) can be used for exposed wiring. Where exposed, it should not be subject to physical damage.

So, as long as it's in the ceiling of the garage and try not to damage it, it will be fine.

"Subject to physical damage" is a very subjective term--requiring a judgement call by the inspector. To determine if your cable is "subject to physical damage", you have to take into consideration many factors. One key factor is how high the ceiling is. Obviously it is more subject to damage in a low ceiling than a high one.
