The idea with this code requirement is that we dont want a heat source, the luminaire, to be in contact with anything that may be stored there. The second location to cover in detail is clothes closets, which is found in 410.16. In 410.16, Clearance and Installation, the requirements are covered depending on the type of luminaire. 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. A metal pole shall be provided with an equipment grounding terminal as follows: A pole with a handhole shall have the equipment grounding terminal accessible from the handhole. Conductor insulation shall be protected from abrasion where it passes through metal. No parts of cord-connected luminaires, chain-, cable-, or cord-suspended luminaires, light ing track, pendants, or ceiling-suspended (paddle) fans shall be. Thermal insulation shall not be installed above a recessed luminaire or within 75 mm (3 in.) These changes can be found in Article 690, Solar Photovoltaic (PV) Systems. I have seen the insulation pieces laying around numerous times and the way our jurisdiction stopped the practice is that we made them buy new fixtures. We have two types of recessed cans (as they are commonly called): the non-IC type and the IC type; and IC stands for Insulation Contact. The design of the single-end luminaires is such that the non-spring tombstone (where the pin inserts into the lamp holder) has two contacts; one is the line voltage and the other is connected to the ballast. Switching. Total Cards. You might ask why this requirement applies to double ended lamp units only. Protection Through Metal. Support. 410.10 Luminaires in Specific Locations. C. Construction Specifications 330.104 Conductors If the ceiling height is adequate to allow a luminaire to be installed above the 8 foot zone, the luminaire must be listed for damp locations; if subject to shower spray, the luminaire must be listed for wet locations. The equipment grounding conductor c. Exit Luminaires. The fittings cannot have general-purpose receptacles. Special bases or other devi ces shall be used for over 1500 watts. 410.8 Inspection. They look the same in size and design, especially during construction. Pendant conductors longer than 900 mm (3 ft) shall be twisted together where not cabled in a listed assembly. D2(b) Optional Calculation for One-Family Dwelling, Air Conditioning Larger than Heating [See 220.82(A) and 220.82(C)], Example No. Luminaires installed on dc circuits shall be equipped with auxiliary equipment and resistors designed for dc operation. These are the 10 NEC Article 410 items we deem most important, based on the pervasiveness of confusion and the potential costs of same. The NEC Wiki|powered by theWikiWP theme andWordPress. Fixtures and lampholders must be securely supported. 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). One note Id like to add regarding these inspections. Such tap conductors shall be in suitable raceway or Type AC or MC cable of at least 450 mm (18 in.) As we all know, heat rises, and a heat pocket is created within each fixture. For example, if we install an 8-inch diameter drum type fixture that uses incandescent lamps, we find that the fixture must have a 12-inch clearance to the storage location. Type IC. 410.110 General. Locations Not Permitted. Many of the items have been created directly as a result of disaster conditions through history. Several codes regulate the use of artificial lighting. New articles and requirements for never before covered systems and equipment such as Class 4 fault-managed circuits, hazardous locations within commercial and industrial cannabis production facilities, equipotential bonding in and around areas with splash pads, insulated bus pipe/tubular covered conductors systems, and more Chapter 5: Special Occupancies. Surface-mounted luminaires (fixtures) can be installed on the wall above the door or on the ceiling. Items such as marking for electrical ratings and warnings for combustibles, conductor and cord usage, and connections are covered. Luminaires Connected Together. best small portable charger for android; international conference on social sciences and humanities 2022; radiator stop leak tablets Integral Thermal Protection. All wiring must be in rigid conduit or threaded steel intermediate metal conduit and will need to have seal fittings installed per 501.15 (A). (D) Bathtub and Shower Areas. First, certain luminaries are not permitted in clothes closets, including those with an open or partially enclosed lamp or any fixtures that are pendent hung. Size. Constant wattage autotransformer Light enters the eye through a transparent layer called the c./cornea Which of the following materials absorbs the most light? Usually we found that the shelf depth in the tract homes we inspected was more than 12 inches, so we had to check the clearance of these closet fixtures during a final inspection. nec article 410 contains requirements for installing. or exceeds 400 mm (16 in.) Luminaires shall be wired so that the screw shells of lampholders are connected to the same luminaire or circuit conductor or terminal. Article 410 is another example of an article in Chapter 4 of the NEC that often doesn't get a lot of emphasis from multi-trade inspectors. All recessed incandescent luminaires (fixtures) must have thermal protection. Transformers of the Oil-Filled Type.

Installation. In Article 100 we find the definition for a clothes closet, which is a non-habitable room or space intended primarily for the storage of garments and apparel. Components of lighting track systems of different voltages shall not be inter changeable. Equipment schedules are important, and one should ask for an equipment schedule during the plan review process, to make sure of what is taking place inside the extraction room and also the surrounding areas. Which section of the NEC requires that at least 6" of free conductor length be left at each outlet box when cutting the branch circuit wires in preparation for connecting a light fixture? Such luminaires shall be permitted to have an additional guard. Many times workers who are shocked dont die from the electrocution, but from the fall. Pendant luminaires (fixtures) or lampholders and incandescent luminaires (fixtures) whose lamps are not totally enclosed. Im not going to cover every one of these items in detail, but please be aware that units installed in wet or damp locations have to be listed for the appropriate location and should prevent water from entering a wiring compartment. Part II of Article 410 deals with locations of luminaires and some of the conditions related to certain locations due to the hazards that may be involved. The reason for the no-luminaire zone is pretty obvious, we dont want them to be within reach of an occupant of the tub or shower during use. In this case, the power to the ballast is disconnected when the lamp is removed. Luminaires over Combustible Material. So, we have to picture the cube directly over the tub or shower, extending 3 feet out from the edge and 8 foot above the unit. A pole with a hinged base shall have the equipment grounding terminal accessible within the base.Exception to (3): No grounding terminal shall be required in a pole2.5 m (8 ft) or less in height abovegrade where the supply wiring method continues without splice or pull, and where the interior of the pole and any splices are accessible by removing the luminaire.

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. All of the electrical equipment and enclosures must be specifically approved for the location [682.10]. Electric-discharge and LED luminaires surface mounted over concealed outlet, pull, or junction boxes and designed not to be supported solely by the outlet box shall be provided with suitable openings in the back of the luminaire to provide access to the wiring in the box. The next key item to address is the use of flush and recessed luminaires, and Part X has special provisions for these.
