There are other requirements in each of these parts that I encourage you to review, since this article only covers the highlights. Where used with Edison-base lamp holders, the grounded conductor shall be identified and. 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.. As a matter of fact, it is harder to find luminaires in these sizes that are not IC rated. Auxiliary equipment, including reactors, capacitors, resistors, and similar equipment, where not instal led as part of a luminaire assembly, shall be enclosed in accessi ble, permanently installed metal cabinets. There are two specific locations I want to cover in this article. Article 411 addresses lighting systems operating at 30V or less. Items such as marking for electrical ratings and warnings for combustibles, conductor and cord usage, and connections are covered. Equipment other than showcases shall not be electrically connected to showcases. In addition to complying with the general requirements for luminaires, such equipment shall comply with Part XII of this article. 410.68 Feeder and Branch-Circuit Conductors and Ballasts. The main item I want to cover here is the poles used to mount area lighting. This restriction is not required if the luminaire (fixture) is installed in poured concrete and is approved for this use or when the luminaire (fixture) by construction design provides characterisitics that are equivalent to thermally protected characteristics, and are identified as such. Luminaires shall be constructed, installed, or equipped with shades or guards so that combustible material is not subjected to temper atures in excess of 90C (194F). 410.52 Conductor Insulation. 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. Portable luminaires shall be wired with flexible cord recognized by 400.4 and an attachment plug of the polar ized or grounding type. 410.59 Cord-Connected Showcases. Often we find shelves that hold cardboard boxes or garments that are easily ignited if in contact with a heat source. 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. They look the same in size and design, especially during construction. 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. 410.64 Luminaires as Raceways. Special Provisions for Flush and Recessed Luminaires (Fixtures). Connection of portable luminaires, portable and mobile signs, or appliances. Lampholders in Wet or Damp Locations. If the wiring system provides a means of grounding, exposed conductive parts must be grounded. 410.62 Cord-Connected Lampholders and Luminaires. Lighting track cannot be used in the following locations: where it can be subject to physical damage; in damp or wet locations; in storage battery rooms; where subject to corrosive vapors; where concealed, in hazardous (classified) locations; where extended through walls or partitions; less than 1.5 m (5 ft.) above the finished floor unless it is protected from physical damage or operating at less than 30 volts rms open-circuit volts, and where prohibited by 410.4(D). 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. The free lead at the end of a group of showcases has a female fitting not extending beyond the case. If you are tasked with doing inspections for parking lot lighting, you need to be familiar with a few items. The NEC specifies a few requirements for outlet boxes, inspection, suspended ceilings, luminaire (fixture) studs, insulating joints, raceway fittings, busways, and trees. 4 in.) The lampholder must be at least 2.5 m (8 ft.) above the floor unless an individual switch is installed for each fixture. Provided with Mogul-Base, Screw Shell Lampholders. The groun ded conductor, where connected to a screw shell lampholder, shall be connected to the screw shell. The next key item to address is the use of flush and recessed luminaires, and Part X has special provisions for these. Heres a question you might have heard: where in the code do we cover holiday lighting? I will not cover each of these here, please review them on your own so that you will be aware of what is in this part of the code. See ANSI/ASTM E842015a,StandardTest Method for Surface Burning Characteristics of Building Materialsor ANSI/UL 7232013,Standard for Test for Surface Burning Characteristics of Building Materials. In this case, the power to the ballast is disconnected when the lamp is removed. Title. Such luminaires shall be permitted to have an additional guard. Insulating joints that are not designed to be mounted with screws or bolts shall have an exterior metal casing, insulated from both screw connections. 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. Secondary Circuit(s). of a ballast, LED driver, power supply, or transformer shall have an insulation temperature rating not lower than 90C (194F), unless supplying a luminaire marked as suitable for a different insulation temperature. Luminaires subject to physical damage, using a mercury vapor or metal halide lamp, installed in playing and spectator seating areas of indoor sports, mixed-use, or all- purpose facilities shall be of the type that protects the lamp with a glass or plastic lens. This term is not to be confused with luminary, which is defined as an important person. The bushing shall be of insulating material unless a jacketed type of cord is used. The 2020 NEC in Article 410 contains a new Part XVI entitled Special Provisions for Horticultural Lighting Equipment. This may create inspection issues, as Ive seen these cord- and plug-connected and hung in various ways that I didnt consider permanent. General II. This article covers luminaires, portable lumin aires, lampholders, pendants, incandescent filament lamps, arc lamps, electric-discharge lamps, decorative lighting products, lighting accessories for temporary seasonal and holiday use, portable flexible lighting products, and the wiring and equip ment forming part of such products and lighting installations. 410.14 Luminaires in Show Windows.

Lamps or lampholders shall be designed so that there are no exposed live parts when lamps are being inserted or removed. 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. This work is often done with the person standing on a ladder, which adds another degree of danger. Lampholders. Open-Circuit Voltage Exceeding 300 Volts. Installed in Poured Concrete. As we all know, heat rises, and a heat pocket is created within each fixture. There is a concern that the lamps may fail in such a way that debris may fall onto people or combustible surfaces. Prescriptive steps for connecting and disconnecting are provided and must be provided on the equipment. However, the only requirements for luminarie installations in closets appear in section 410.16, which specifically addresses luminaires in clothes closets. Tap Conductors. The ballast of a fluorescent luminaire installed indoors shall have integral thermal protec tion. Everyone knows what a closet is, right? Luminaires installed on dc circuits shall be equipped with auxiliary equipment and resistors designed for dc operation. Now lets review the definition in 410.2, which further defines what closet storage space is within a clothes closet.
