Busways. with a cover suitable for use in wet locations to provide access to the supply terminations within the pole or pole base.Exception No. A recessed remote ballast for a high-intensity discharge luminaire shall have thermal protec tion that is integral with the ballast and shall be identified as thermally protected. 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 last item I will cover in this article is Part XIV Lighting Track, or as it is more commonly called, track lighting. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association. For some reason, these are not commonly purchased with an IC rating. Portable Handlamps. Luminaire studs that are not a part of outlet boxes, hickeys, tripods, and crowfeet shall be made of steel, malleable iron, or other material suitable for the applica tion. In other words, the lamp is the disconnect. Chain-supported lumin aires used in a show window shall be permitted to be externally wired. The term luminaires is recommended by the International Electrotechnical Commission. Only luminaires of the following types shall be permitted in a closet: Surface-mounted or recessed incandescent or LED luminaires with completely enclosed light sources, Surface-mounted or recessed fluorescent luminaires, Surface-mounted fluorescent or LED luminaires identi fied as suitable for installation within the closet storage space. 410.10 (D) Bathtub and Shower Areas. This requirement affects double ended fluorescent lamp luminaires. Installation. Prescriptive steps for connecting and disconnecting are provided and must be provided on the equipment. Surface-mounted luminaires (fixtures) can be installed on the wall above the door or on the ceiling. a disconnecting means either internal or external to each luminaire (fixture), to disconnect simultaneously from the source of supply all conductors of the ballast, including the grounded conductor if any. Tap conductors of a type suitable for the temperature encountered shall be permitted to run from the luminaire terminal connection to an outlet box placed at least 300 mm (1 ft) from the luminaire. For example, if the illumination equipment is in a hazardous location, apply Articles 500 through 517. A metal pole with a hinged base shall have the hinged base and pole bonded together. The track conductors shall be a minimum 12 AWG or equal and shall be copper. In addition to complying with the general requirements for luminaires, such equipment shall comply with Part XIII of this article. Title.

GET YOUR CEUS TODAY, 1998-2021. D4(b) Optional Calculation for Multifamily Dwelling, Example No. D10 Feeder Ampacity Determination for Adjustable-Speed Drive Control [See 215.2, 430.24, 620.13, 620.14, 620.61, Tables 430.22(E), and 620.14], Example No. Listed clips identified for use with the type of ceiling framing member(s) and lumin aire(s) shall also be permitted. constant wattage autotransformer All luminaires, lampholders, and retrofit kits shall be listed. The load calculation in 220.43(B) shall not be required to limit the length of track on a single branch circuit, and it shall not be required to limit the number of luminaires on a single track. 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. The canopyshall be permitted to include a section of raceway not over150 mm (6 in.) between the first case and the supply receptacle. If no provision for grounding is available, they must be insulated. See Figure 410.2. Portable luminaires shall be wired with flexible cord recognized by 400.4 and an attachment plug of the polar ized or grounding type. Wiring methods and materials supplying the luminaire(s) shall not be exposed within the cooking hood. 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 1999 National Electrical Code (NEC) Section 410-66 gives rules for non-Type-IC recessed luminaire clearance from combustible materials and thermal insulation: "A recessed fixture that is not identified for contact with insulation shall have all recessed parts spaced at least 1/2 in. 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. 2: No handhole shall be required in a pole 6.0 m (20 ft) or less in height abovegrade that is provided with a hinged base. 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. 410.14 Luminaires in Show Windows. This is usually not an issue on 6 or 7 inch recessed cans, as they are typically IC rated and easily checked. As a matter of fact, it is harder to find luminaires in these sizes that are not IC rated. Framing members of suspended ceil ing systems used to support luminaires shall be securely fastened to each other and shall be securely attached to the building structure at appropriate intervals. 410.90 Screw Shell Type. No unnecessary splices or taps shall be made within or on a luminaire.Informational Note: For approved means of making connec tions, see 110.14. Deleted. Inherently Protected.

D9 Feeder Ampacity Determination for Generator Field Control, Example No. Parts VI through IX deal with items generally covered by the manufacturers of the luminaires. Wiring on or within luminaires shall be neatly arranged and shall not be exposed to physical damage. D6 Maximum Demand for Range Loads, Example No. Chapter 3: Wiring Methods and Materials. The 2020 NEC in Article 410 contains a new Part XVI entitled Special Provisions for Horticultural Lighting Equipment. 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. Independent of the Outlet Box. 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). However, the only requirements for luminarie installations in closets appear in section 410.16, which specifically addresses luminaires in clothes closets. Dwelling Occupancies. There are a couple of exceptions, so please review these. Surface-mounted fluorescent or LED luminaires shall be permitted to be installed within the closet storage space where identified for this use. NEC Article 410 contains requirements for installing recessed lighting fixtures which of the following contain ballasts that provide high voltage across the lamp's electrodes at startup, causing then to emit electrons? Inlets and connectors shall be permitted to be of a lower ampere rating than the branch circuit but not less than 125 percent of the luminaire load current. For inspections related to location of a luminaire within a closet, we cant install the luminaire within the modified cube shape described in the definition. Autotransformers. In addition to complying with the general requirements for luminaires, such equipment shall comply with Part XII of this article. Outdoor luminaires and associated equipment shall be permitted to be supported by trees. Fastening. Separate Mounting. Raceway fittings used to support a luminaire(s) shall be capable of supporting the weight of the complete fixture assembly and lamp(s). Equipment for use with electric-discharge lighting systems and designed for an open-circuit voltage of 1000 volts or less shall be of a type identified for such service. However, Ive had inspectors try to apply the requirements for closets in 410 to other locations. Additional Requirements. 410.84 Cord Bushings. Lamp Terminals and Lampholders. There is a concern that the lamps may fail in such a way that debris may fall onto people or combustible surfaces. 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. In a completed installa tion, each outlet box shall be provided with a cover unless covered by means of a luminaire canopy, lampholder, recepta cle, or similar device. Part III. Normally, luminaires (fixtures) cannot be used as raceways. Luminaires installed on dc circuits shall be equipped with auxiliary equipment and resistors designed for dc operation. This includes cables, conductors, wiring devices, and others. 4 in.) Individual showcases, other than fixed, shall be permitted to be connected by flexible cord to permanently installed receptacles, and groups of not more than six such showcases shall be permitted to be coupled together by flexible cord and separable locking-type connec tors with one of the group connected by flexible cord to a permanently installed receptacle. Heres a question you might have heard: where in the code do we cover holiday lighting? The clearance between the luminaire (fixture) and nearest point of storage must be 300 mm (12 in.) Equipment that has an open- circuit voltage exceeding 1000 volts shall not be installed in or on dwelling occupancies. 150 mm (6 in.) long and not more than 1.8 m (6 ft.) long, be a suitable raceway or the tap conductor must be Type AC or MC cable. All luminaires installed in wet locations shall be marked, Suitable for Wet Locations. All luminaires installed in damp locations shall be marked Suitable for Wet Locations or Suitable for Damp Locations.. For existing installed lumin aires without disconnecting means, at the time a ballast is replaced, a disconnecting means shall be installed. from lamp terminals shall not be required to be grounded. 410.46 Equipment Grounding Conductor Attachment. nec article 410 contains requirements for installingcushion foundation case A luminaire assembly equipped with a strain reliefand canopy shall be permitted to use a cord connectionbetween the luminaire assembly and the canopy. However, in locations such as small alcoves or similar areas where 4 inch cans are installed, we may find problems. A bushing or the equivalent shall be provided where flexible cord enters the base or stem of a porta ble luminaire. 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). Lighting track shall be securely mounted so that each fastening is suitable for supporting the maximum weight of luminaires that can be installed. Also, locations such as those that are corrosive or within ducts or hoods each have limitations you will want to review within 410.10 if inspecting these areas. This often leads to problems, such as when we have special luminaires used inside casinos, hotels and other large facilities where the units are actually a piece of artwork with lights attached. General II. Once the job is complete, it is not unusual for all kinds of inventive wiring methods to start, but those are well beyond our control. Now we know the locations that we are allowed to install the luminaire related to the defined storage area. D5(b) Optional Calculation for Multifamily Dwelling Served at 208Y/120 Volts, Three Phase, Example No. The groun ded conductor, where connected to a screw shell lampholder, shall be connected to the screw shell.
