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. Metal Cabinets. In addition to complying with the general requirements for luminaires, such equipment shall comply with Part XIII of this article. Refer to 310.15 or 310.60 for 14 AWG and larger conductors. Exposure to Damage. Receptacles, Connectors, and Attachment Plugs. The conductors shall be installed within the track housing, permit ting insertion of a luminaire, and designed to prevent tamper ing and accidental contact with live parts. Part X. 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. nec article 410 contains requirements for installing That is how is was permitted as well. ), or more than 300 mm (12 in.) 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 Recessed luminaires (fixtures) can be installed in the wall or ceiling.

One category that is a fairly new concern is indoor sports, mixed use and all-purpose facilities that may utilize mercury vapor or metal halide lamps. A ballast in a fluorescent luminaire that is used for egress lighting and energized only during a fail ure of the normal supply shall not have thermal protection. Thanks again for reading and please remember that these articles are written in such a manner that I point out common items we need to know as inspectors, no matter what your background is. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association. Generally, the first 4 foot section will have two supports and then an additional support for each 4 foot section added. (A) General. The issue here is that these luminaires have the possibility of generating a lot of heat, and the lamp is designed to be installed inside a metallic housing, which is then installed at the top of a room in the ceiling. Chain-supported lumin aires used in a show window shall be permitted to be externally wired.

The ballast of a fluorescent luminaire installed indoors shall have integral thermal protec tion. The first is related to locations in and near bathtub and shower areas. Where supplied by a circuit having a grounded conductor, the grounded conductor shall be connected to the screw shell. Additional Requirements. There are two specific locations I want to cover in this article. Luminaires shall be wired so that the screw shells of lampholders are connected to the same luminaire or circuit conductor or terminal. Receptacles and attachment plugs shall be permitted to be of a lower ampere rating than the branch circuit but not less than 125 percent of the luminaire full-load current. Such tap conductors shall be in suitable raceway or Type AC or MC cable of at least 450 mm (18 in.) (B) Metal or Nonmetallic Poles Supporting Luminaires (Lighting Fixtures). The lampholder must be at least 2.5 m (8 ft.) above the floor unless an individual switch is installed for each fixture. 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. The fixtures must be installed in a manner so that water will not enter or collect in the lampholder, wireway, etc. The installation requirements for motor control centers are covered in 110.26 (F), and air-conditioning and refrigerating equipment are covered in Article 440. C. Construction Specifications 330.104 Conductors Article 430 contains the specific rules for conductor sizing, overcurrent protection, control circuit conductors, motor controllers, and disconnecting means.

Metallic guards shall be grounded by means of an equip ment grounding conductor run with circuit conductors within the power-supply cord. Therefore, these fixtures now require a disconnecting means. As we all know, heat rises, and a heat pocket is created within each fixture. All luminaires shall be marked with the maxi mum lamp wattage or electrical rating, manufacturers name, trademark, or other suitable means of identification. Equip ment having an open-circuit voltage exceeding 300 volts shall not be installed in dwelling occupancies unless such equipment is designed so that there will be no exposed live parts when lamps are being inserted, are in place, or are being removed.

You cannot support a fixture by the screw shell of a lampholder if it weighs more than 3 kg (6 lb.) Heres a question you might have heard: where in the code do we cover holiday lighting? 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. Professional. The clearance between the luminaire (fixture) and nearest point of storage must be 150 mm (6 in.). Like Ive mentioned before, be proactive when you are starting a new project and let the contractor know from the beginning (before the products show up on the jobsite) that you will be checking for this. Lamp tie wires, mount ing screws, clips, and decorative bands on glass spaced at least 38 mm (112in.)

The connected load on lighting track shall not exceed the rating of the track. III. 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. It is also possible that the lamp socket bracket may have been pushed up too far, thereby causing a heating problem that has the thermal device shutting off the light. The next key item to address is the use of flush and recessed luminaires, and Part X has special provisions for these.
