Where a luminaire is recessed in fire-resistant material in a building of fire-resistant construction, a temperature higher than 90C (194F) but not higher than 150C (302F) shall be considered acceptable if the luminaire is plainly marked for that service. The separation between cases is not in excess of 50 mm (2 in. This becomes a challenge because insulation has the tendency to go everywhere if it is blown in; or if it is batt insulation, it may eventually fall onto a fixture. The clearance between the luminaire (fixture) and nearest point of storage must be 150 mm (6 in.). Lamps shall not be located where normally exposed to physical damage. Busways. of the recessed luminaires enclosure, wiring compartment, ballast, transformer, LED driver, or power supply unless the luminaire is identified as Type IC for insulation contact.

The clearance between the luminaire (fixture) and nearest point of storage must be 300 mm (12 in.) I will not go into detail here, but the scope has a laundry list of items and you will find that it is pretty exclusively related to lighting products and devices. Luminaires listed and marked for use as a raceway shall be permitted to be used as a raceway. Along with making sure they have used lamps that are not larger than the luminaire allows per its listing and labeling, these little foil-covered insulation pieces are part of the fixture and are there to ensure we dont have heat transfer from the lamp to the wire terminations. Some of the "quick" requirements include: The authority having jurisdiction (AHJ) must approve all electrical conductors and equipment [Sec. The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. General.

Equipment that has an open- circuit voltage exceeding 1000 volts shall not be installed in or on dwelling occupancies. Secondary Circuit(s). If they were installed in a ceiling, we had the installer frame a box out around the fixtures to maintain the required 3 inch clearance from insulation. 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. D2(b) Optional Calculation for One-Family Dwelling, Air Conditioning Larger than Heating [See 220.82(A) and 220.82(C)], Example No. Where supplied by the ungrounded conductors of a circuit, the switching device of lampholders of the switched type shall simultaneously disconnect both conductors of the circuit. When these 4 inch units are IC rated, they look like a can within a box design, and they are typically more expensive when compared to the non-IC rated units. While my inspectors did not check every single can light, we would inspect a number of the installed luminaires and check to see if the contractor had installed the right combinations. The luminaire shall be constructed so that all exhaust vapors, grease, oil, or cooking vapors are excluded from the lamp and wiring compartment. 410.70 Combustible Shades and Enclosures. In this case, the power to the ballast is disconnected when the lamp is removed. Don't let this Article's length and degree of detail throw you. Decorative Lighting and Similar Accessories. The grounding terminations within the poles are often difficult to install and also inspect. This term is not to be confused with luminary, which is defined as an important person. Accessible.

Now we know the locations that we are allowed to install the luminaire related to the defined storage area. Article 410 is another example of an article in Chapter 4 of the NEC that often doesnt get a lot of emphasis from multi-trade inspectors. Lampholders installed over highly combustible material shall be of the unswitched type. Luminaires shall be permitted to be connected to busways in accordance with 368.17(C).
