I want to install fluorescent strip lights on a sheetrock ceiling. Can I support the fixtures directly over the recessed outlet box and connect to the branch-circuit wiring through a chase nipple?

Q. I want to install fluorescent strip lights on a sheetrock ceiling. Can I support the fixtures directly over the recessed outlet box and connect to the branch-circuit wiring through a chase nipple?

A. No. When an electric-discharge luminaire is surface mounted over a concealed outlet box, and not solely supported by the outlet box, the luminaire must be provided with suitable openings that permit access to the branch-circuit wiring within the outlet box [410.14(B)].
