I intend to install motion-activated lights outside a garage (there is a breaker panel with available capacity for lighting).
I can run regular NMB #14/2wG wire within the open walls or down from the eaves. I know to use a waterproof junction box. What's the best way to get the wire into the box without exposing the cable to UV light or to moisture? I'd like to keep it simple, avoiding conduit etc.
My thought is to drill an oversized hole in the wall and put a waterproof cable bushing on the box's back knockout. The wire won't be exposed and would be behind a waterproof box, around which I'll caulk. Is this a safe and economical approach?
