    Light installation question - fluor. fixture on drywall ceiling

    Say a 4 foot fluorescent fixture on a drywall ceiling:
    Is a box in the ceiling required? (if yes - what NEC reference?)
    Or can NM wiring be connected directly to the fixture?

    What do you (opinion) think would have been done in the 70s in a low cost multifamily? (4 ft kitchen fixture)

    (An odd question I know, but applies to fixture replacement where the ceiling potentially has asbestos) (I could go look but the apartments in question are over an hour away)

    No box needed.

    I will look up code section in a minute.

    (B) Equipment. An integral junction box or wiring compartment
    as part of approved equipment shall be permitted
    in lieu of a box.

    This assumes the fixture has such an integral box. Most do, however I have installed fluorescent fixtures that did not and required an external box. Usually the very cheap ones.

    Actually I assume no box, integral or not, cable/wire is just attached with a connector and spliced internally to the ballast.

    I agree, that would be considered the aforementioned wiring compartment.

    I would assume no box. If there is one present, it has to be accessible w/o taking down the fixture.

    You have another potential problem: most new fixtures require connection to 90*C wire. Doubt that 40+ year old NM is rated for it.

    What part do you think will be asbestos?

    PS: Asbestos is not like a Black Mamba, instantaneous and deadly. A respirator that filters anything will work on Asbestos. Here, there's a metric ton of it as siding, so long as you dont drill or grind it, you can remove it, and throw it away, w/o even a permit (pipe insulation is a TOTALLY different animal). You're not going to get Mesothelioma from cutting one hole in a ceiling, or disturbing its insulation.
