Re: Lighting outlet Box
Generally speaking, all connections, junctions, and splices should take place within a box. However, some fixtures are listed as use with space allowances for fixture lead connections to branch-circuit wiring. Some fixtures are listed as raceways as well. See Section III of Article 410 including 410.31 and 410.32 for additional box/fixture requirements. Aslo see Article 310.15(J).
