Which section of the NEC requires that at least 6" of free conductor length be left at each outlet box when cutting the branch circuit wires in preparation for connecting a light fixture? The second location to cover in detail is clothes closets, which is found in 410.16. Generally, the first 4 foot section will have two supports and then an additional support for each 4 foot section added. If we miss this, then there may be an issue that can lead to a fire. If the ceiling height is adequate to allow a luminaire to be installed above the 8 foot zone, the luminaire must be listed for damp locations; if subject to shower spray, the luminaire must be listed for wet locations. Circuit Conductors. This type of luminaire (fixture) must comply with Sections 410.65 through 410-72. 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.

You cannot have any part of a suspended fixture (i.e., the cord, pendant chain, etc.) General II. Location. Wet and Damp Locations. Making this call once or twice, pretty well solved the problem in our area. 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. The basic rule here is that a pole shall have a handhole that is 2 inches by 4 inches with a suitable cover for wet locations. Listing. It is permitted, however, if the luminaire (fixture) is listed for that use. Exposed Components. Tap Conductors. Where supplied by a circuit having a grounded conductor, the grounded conductor shall be connected to the screw shell. in any dimension. If you are tasked with doing inspections for parking lot lighting, you need to be familiar with a few items. 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). Informational Note: See Article 100 for the definition ofMulti wire Branch Circuit.

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? Auxiliary equipment for electric-discharge lamps shall be enclosed in noncombustible cases and treated as sources of heat. Informational Note: For ampacity of fixture wire, maximum operating temperature, voltage limitations, minimum wire size, and other information, see Article 402. If they were installed in a ceiling, we had the installer frame a box out around the fixtures to maintain the required 3 inch clearance from insulation. The terminal of an electric-discharge lamp shall be considered as a live part. Exposed metal parts shall be connected to an equipment grounding conductor or insulated from the equipment grounding conductor and other conducting surfaces or be inaccessible to unqualified personnel. Branch-circuit conductors that have an insulation suitable for the temperature encountered shall be permitted to terminate in the luminaire.

Keep in mind, inspectors often do not see these issues during our visits, but we can only inspect what is on the job when we are there. Cord Requirements. However, the only requirements for luminarie installations in closets appear in section 410.16, which specifically addresses luminaires in clothes closets. Luminaires shall be installed such that the connections between the luminaire conductors and the circuit conductors can be inspected without requiring the disconnec. Suspended Ceilings. This may create inspection issues, as Ive seen these cord- and plug-connected and hung in various ways that I didnt consider permanent. This month we will continue the series of articles covering basic electrical inspection items.
