I need to install a permanent wiring from a receptacle on the ceiling of finished garage to outside of garage (for motion-sensor flood light). The wire will not be below 9 feet level.
Do I need to use conduit in the first place?
Assuming yes - I'm planning to extend an outlet, replace with GFCI and then run the wire through PVC conduit attached to the ceiling. Second question - can I run wire directly through the wall from PVC conduit? Or do I need to connect it to a junction box (and then from junction box to run wire through the wall)?
