Exposure to Damage. You cannot support a fixture by the screw shell of a lampholder if it weighs more than 3 kg (6 lb.) Lampholders. Such luminaires shall be permitted to have an additional guard. 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. 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.

This may create inspection issues, as Ive seen these cord- and plug-connected and hung in various ways that I didnt consider permanent. 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 fixtures must be installed in a manner so that water will not enter or collect in the lampholder, wireway, etc. Transformers of the oil-filled type shall not be used.

Transformers shall have a secondary short-circuit current rating of not more than 150 mA if the open-circuit volt age is over 7500 volts, and not more than 300 mA if the open- circuit voltage rating is 7500 volts or less. It is permitted, however, if the luminaire (fixture) is listed for that use. The first definition found in 410.2 is for closet storage space. Wet and Damp Locations. This location is permitted only in nonresidential cooking areas and is subject to four specific conditions. 410.46 Equipment Grounding Conductor Attachment. Items such as marking for electrical ratings and warnings for combustibles, conductor and cord usage, and connections are covered. Some of the articles include provisions pertaining to switches, receptacles, switchboards and panelboards, industrial control panels, luminaires, appliances, air-conditioning and refrigeration equipment, and transformers. 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.

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). For example, if the illumination equipment is in a hazardous location, apply Articles 500 through 517. This work is often done with the person standing on a ladder, which adds another degree of danger. 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. 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. Diffusers shall be resistant to thermal shock. Conductors that have insulation suitable for the temperature encountered shall be used. Also in part (B), the clearance to any insulation is required to be at least 3 inches. More times than not, these custom one-of-a-kind units are not typically listed and labeled by a Nationally Recognized Testing Laboratory (NRTL). 410.18 Space for Cove Lighting. in length and intended to facilitate the connection to an outlet box mounted above a suspended ceiling. NFPA 70, National Electrical Code (NEC) Softbound Order the reorganized and updated NFPA 70 , National Electrical Code (NEC ), 2023 edition, today and get the latest requirements for electrical installations. The means for providing illumination has gone through numerous changes over the centuries, from oil lamps to incandescent bulbs, to fluorescent tubes and LEDs. He has been a master electrician since 1988. A means to connect an equipment ground must be provided for a metal luminaire (fixture). Temperature. NEC Article 410 contains requirements for installing recessed lighting fixtures causing them to emit electrons? 400.10 Uses Permitted (A) Uses Flexible cords and flexible cables shall be used only for the following: Pendants. These changes can be found in Article 690, Solar Photovoltaic (PV) Systems. Open-Circuit Voltage Exceeding 300 Volts. Part IV is titled Luminaire Supports. 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. Often we find shelves that hold cardboard boxes or garments that are easily ignited if in contact with a heat source. So at first, the contractor had to field install these devices, but eventually manufacturers started to ship units with the disconnects installed. This becomes a challenge because insulation has the tendency to go everywhere if it is blown in; or if it is batt insulation, it may eventually fall onto a fixture. 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. but not more than 1.8 m (6 ft) in length. Installed in Poured Concrete. Wiring Supplying Luminaires (Fixtures) Connected Together, VII. Lamp tie wires, mount ing screws, clips, and decorative bands on glass spaced at least 38 mm (112in.) The NEC specifies a few requirements for outlet boxes, inspection, suspended ceilings, luminaire (fixture) studs, insulating joints, raceway fittings, busways, and trees. 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. Combustible Material. However, the requirements within this article are important to know and enforce. 410.73 (G) Handbook Commentary Section 410.73 (G) was added to the 2005 Code with an effective date of January 1, 2008. . Luminaires listed and marked for use as a raceway shall be permitted to be used as a raceway. Excess wiring shall be avoided. with a cover suitable for use in wet locations to provide access to the supply terminations within the pole or pole base.Exception No. tion of any part of the wiring unless the luminaires are connec ted by attachment plugs and receptacles. Unless an individual switch is provided for each luminaire, lampholders shall be located at least 2.5 m (8 ft) above the floor or shall be located or guarded so that the lamps cannot be readily removed or damaged. Fastening. Lampholders installed over highly combustible material shall be of the unswitched type. 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. 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. Luminaires in Indoor Sports, Mixed-Use, and All-Purpose Facilities. Secondary circuit outputs shall not be connected in parallel or in series. Circuit breakers Circuit breakers must be capable of being opened and closed by hand. Metal Halide Lamp Containment. 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. Multiwire Branch Circuits. constant wattage autotransformer You may need to comply with more stringent requirements for lights than those contained in Article 410.
