I'm wondering if anyone has some definite way to interpret 410.14(B). I've seen inumerable fluorescent light fixtures attached to concrete ceilings (usually industrial/institutional) with just a 1/2 chase nipple for "access" to the J-box. Obviously, to get at the wiring you'd have to remove the fixture. I tried to convince a local inspector that he shouldn't allow this, but he didn't have any interest. He considered fluorescent fixtures to NOT be "Electric-Discharge" lighting and so he didn't think the section cited applied. What do you all think?
