So on a non-IC type we must have a 1/2 inch space from any recessed parts to combustibles, excluding the support or finish trims. for an incandescent luminaire (fixture) and 150 mm (6 in.) The issue here is that these luminaires have the possibility of generating a lot of heat, and the lamp is designed to be installed inside a metallic housing, which is then installed at the top of a room in the ceiling. 410.10 (D) Bathtub and Shower Areas. You probably guessedit is the last item in Article 410, and it states that holiday lighting shall be in accordance with Article 590.3(B).

The separation between cases is not in excess of 50 mm (2 in. A common problem here is that a contractor will use a particular brand of recessed can, and then trim them out with a different brand of trim; since those items were not tested together, this is a violation of the IC listing of the recessed can. One of the requirements is that these units must have a thermal protection device that will disconnect the lamp if the temperature limit is exceeded. Special Provisions for Flush and Recessed Luminaires (Fixtures). Through-Wiring. on either side of the rod on a plane horizontal to the floor extending the entire length of the rod.
