Live Parts. A recessed luminaire that is identified for contact with insulation, Type IC, shall be permitted to be in contact with combustible materials at recessed parts, points of support, and portions passing through or finishing off the opening in the building structure. Exception No. There are two specific locations I want to cover in this article. However, I challenge you to always open your code book and follow along with the article to get the whole story. Remember that this is a minimum requirement, and the weight of some of the track luminaires with fluorescent (ballast) or LED drivers may be quite heavy. This requirement provides a safe method to service the ballast, and continues to be extended in its enforcement, adding that in existing installations the disconnecting means shall be added when ballast replacement is performed. 2: Replacement luminaires shall be permitted to connect an equipment grounding conductor from the outlet in compliance with 250.130(C). 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. One important requirement to note is that a fixture can be supported from an outlet box if the outlet box is required by 314.23 and complies with 314.27 (A) and 314.27 (B). 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. 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. Recessed lighting is an item I emphasize as one of the most important items for inspections. Transformers shall be located so that adjacent combustible materials are not subjec ted to temperatures in excess of 90C (194F). Wet and Damp Locations. Lampholders installed in damp locations shall be listed for damp locations or shall be listed for wet locations. Wiring methods and materials supplying the luminaire(s) shall not be exposed within the cooking hood. One additional 2-wire branch circuit separately supplying one or more of the connected luminaires shall also be permit ted.

D8 Motor Circuit Conductors, Overload Protection, and Short-Circuit and Ground-Fault Protection, Example No. Chapter 5: Special Occupancies. Article 410 provides the requirements for installing luminaires, lampholders, lamps, and decorative lighting products on circuits greater than 30V. The luminaire shall be constructed so that all exhaust vapors, grease, oil, or cooking vapors are excluded from the lamp and wiring compartment. 410.54 Pendant Conductors for Incandescent Filament Lamps. The NEC specifies a few requirements for outlet boxes, inspection, suspended ceilings, luminaire (fixture) studs, insulating joints, raceway fittings, busways, and trees. Luminaires installed in wet or damp locations shall be installed such that water cannot enter or accumulate in wiring compartments, lampholders, or other electrical parts. Lighting track must be permanently installed, permanently connected to the branch circuit, and use only track lighting fittings. If you see a cord plugged into a device on a trackthat is a violation. Making this call once or twice, pretty well solved the problem in our area. Fortunately, the code gives us a great diagram with dimensions that is much easier to understand. Construction of Flush and Recessed Luminaires (Fixtures), XIII. Luminaires installed on dc circuits shall be equipped with auxiliary equipment and resistors designed for dc operation. Such tap conductors shall be in suitable raceway or Type AC or MC cable of at least 450 mm (18 in.) 02/08/2017.

The volume bounded by the sides and back closet walls and planes extending from the closet floor vertically to a height of 1.8 m (6 ft) or to the highest clothes- hanging rod and parallel to the walls at a horizontal distance of 600 mm (24 in.) Exposed Components. 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. In 410.16, Clearance and Installation, the requirements are covered depending on the type of luminaire. 150 mm (6 in.) 410.40 General. | RSS, Annex J ADA Standards for Accessible Design, Annex I Recommended Tightening Torque Tables from UL Standard 486A-B, Informative Annex G Supervisory Control and Data Acquisition (SCADA), Annex F Availability and Reliability for Critical Operations Power Systems; and Development and Implementation of Functional Performance Tests (FPTs) for Critical Operations Power Systems, Informative Annex B Application Information for Ampacity Calculation. This month we will continue the series of articles covering basic electrical inspection items. Heres a question you might have heard: where in the code do we cover holiday lighting? Conductors shall be arranged so that the weight of the luminaire or movable parts does not put tension on the conductors. 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. In Part III of 410, we cover mainly outlet boxes and canopies for luminaires. Thermal Protection Fluorescent Luminaires. Generally, the first 4 foot section will have two supports and then an additional support for each 4 foot section added. 410.90 Screw Shell Type. Diffusers shall be resistant to thermal shock. The switch or circuit breaker shall be located within sight from the luminaires or lamps, or it shall be permitted to be located elsewhere if it is lockable in accordance with 110.25. Connection of Electric-Discharge and LED Luminaires. 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. However, in locations such as small alcoves or similar areas where 4 inch cans are installed, we may find problems. 150 mm (6 in.) The purpose of the NEC is to provide electrical installation requirements that protect persons and property from electrical hazards arising from the use of electricity. Outlet Boxes. 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 terminals of an electric- discharge lamp shall be considered as energized where any lamp terminal is connected to a circuit of over 300 volts. In other words, the lamp is the disconnect. Raceway fittings used to support a luminaire(s) shall be capable of supporting the weight of the complete fixture assembly and lamp(s). These changes can be found in Article 690, Solar Photovoltaic (PV) Systems. Transformers of the Oil-Filled Type.

Five exceptions exist in the 2011 Code, so please review. Luminaires shall be constructed such that adjacent combustible material is not subject to tempera tures in excess of 90C (194F). Simple Reactance Ballasts. The last thing we want is to have a heat source that may ignite some material within the ceiling and cause an attic fire. However, the only requirements for luminarie installations in closets appear in section 410.16, which specifically addresses luminaires in clothes closets. The next important item is 410.6, which states that all luminaires and lamp holders shall be listed. Type. Then, if you see something that just doesnt look right during an inspection, you will know where to go to verify the code requirements. Circuit Conductors. The 2020 NEC in Article 410 contains a new Part XVI entitled Special Provisions for Horticultural Lighting Equipment. 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. If we miss this, then there may be an issue that can lead to a fire. Fittings identified for use on lighting track shall be designed specifically for the track on which they are to be installed. Luminaires Connected Together. Multiwire Branch Circuits. A toggle bolt pushed through a lay-in ceiling tile will likely not be adequate. 3: Where no equipment grounding conductor exists at the outlet, replacement luminaires that are GFCI protected shall not be required to be connected to an equipment grounding conductor. If you try to read the definition, it might be a little confusing trying to imagine the shape from the language. Voltage. They must be installed so that any adjacent combustible material will not be subjected to a temperature higher than 90C (194F). 410.56 Protection of Conductors and Insulation.

(D) Bathtub and Shower Areas. Total Cards. Introductioin to the National Electrical Code. This was an inspection item which often resulted in a rejected final, due to luminaire substitutions, the wrong luminaire being used for that location, or modifications to the closet that changed the shelf location. Part IV is titled Luminaire Supports. Use Table 402.5 for 18-16 AWG conductors. Considered as Energized. 150 mm (6 in.) There are issues related to combustibles due to the heat that is generated by traditional lighting methods. This term is not to be confused with luminary, which is defined as an important person. They look the same in size and design, especially during construction. Through-Wiring. Listed clips identified for use with the type of ceiling framing member(s) and lumin aire(s) shall also be permitted. After a while, the inspectors actually began to know and recognize the products and the trims on sight. Informational Note: See Article 100 for the definition ofMulti wire Branch Circuit. Luminaires and equipment shall be mechanically connected to an equipment grounding conductor as specified in 250.118 and sized in accordance with 250.122. There are a couple of exceptions, so please review these. Conductors shall be secured in a manner that does not tend to cut or abrade the insulation. If the wiring system provides a means of grounding, exposed conductive parts must be grounded. A couple of notes here from field experience: if the resident complains that the luminaires are shutting off and on randomly, it is likely that the lamps are oversized for the luminaire or the wrong trim is being used. Installed in Poured Concrete. A brief note regarding 410.18 Space for Cove Lighting: the code states that cove lighting shall have adequate space so that lamps and equipment can be properly installed and serviced. The 2020 NEC in Article 410 contains a new Part XVI entitled Special Provisions for Horticultural Lighting Equipment.
