What are the guidelines for recessed incandescent luminaires not marked IC?
(84) VerifiedRecessed incandescent luminaires not marked Type IC and those marked for installing directly in poured concrete must not have insulation over the top of the luminaire. In addition, the insulation must be kept back at least 3 in. (75 mm) from the sides of the luminaire. Other combustible material must be kept at least 1.2 in. (13 mm) from the luminaire except at the point of support.
Watch for markings on the luminaire for maximum clearances, maximum lamp wattage, and temperature ratings for the supply conductors.
What are the stipulations relevant to lamps in new energy conservation laws that have been enacted in some states?
(65) VerifiedThe new laws in these states simply require that lamps in permanently installed luminaires:
-have high efficacy rating (high lumens per watt), or
-be controlled by occupancy sensors, or
-have a combination of lamp efficacy, occupancy sensor control, and/or dimmers.
Cord-connected floor or table lamps are not governed by current energy conservation laws. Most fluorescent lamps with energy savings ballasts, compact fluorescent lamps (CFLs), LEDs, and halogen lamps meet this high-efficacy requirement. Conventional incandescent lamps do not.
Most fluorescent lamps with energy savings ballasts, compact fluorescent lamps (CFLs), LEDs, and halogen lamps meet the high-efficacy requirement._________ do not.
(72) A(n)_________ branch circuit must supply only line-to-neutral loads if the luminaires are connected line-to-neutral.
(79) Type_________ luminaires are permitted to be installed in direct contact with thermal insulation.
(92) Recessed luminaires are usually supported by_________ that are attached to the luminaires' roughin box.
(79) For fluorescent and HID luminaires, the volt-ampere allowance is based on the rating of the_________ .
(83) For surface-mounted and pendant-hung luminaires, support rods should be placed so that they extend about _________in. below the finished ceiling.
(64) Beginning with the 2008 edition of the National Electrical Code, the term luminaire is used exclusively. Previous editions of the NEC® used the term luminaire followed by the term_________ in parentheses.
(74) It is necessary that the illumination of a building comply with energy codes. These codes usually evaluate the illumination on the basis of the average_________ per square foot (meter) of illumination load.
(71) Describe the rules governing the disconnecting means for fluorescent luminaires.
(81) Recessed luminaires have to be securely fastened to the ceiling framing members using bolts, screws, or_________ .
(82) Multiwire branch circuits are defined in NEC® Article 100 as a branch circuit that consists of two or more_________ conductors that have a voltage between them, and a grounded conductor that has equal voltage between it and each ungrounded conductor of the circuit and that is connected to the neutral or grounded conductor of the system.
(82) All recessed incandescent luminaires must be equipped with factory-installed thermal protection, unless the luminaire is identified for use and installed in _________.
(91) The installation of luminaires, lighting outlets, and supports is covered in Article 410 of the NEC®. Article 410 sets forth the basic requirements for the installation, commonly referred to as the "_________ "
(72) Both Type THWN-2 and Type_________ conductors have an insulation temperature rating of 90 degrees Celsius and generally meet the temperature requirement for connecting luminaires.
(68) Incandescent, open, or_________lamps in lampholders; pendant luminaires; and pendant lampholders are not permitted in clothes closets.
