shall not be required in a recessed luminaire whose design, construction, and thermal performance characteristics are equivalent to a thermally protected luminaire and are identified as inherently protected.
410.116 Clearance and Installation. (A) Clearance.
(1) Non-Type IC. A recessed luminaire that is not identi- fied for contact with insulation shall have all recessed parts spaced not less than 13 mm (V2 in.) from combustible materials. The points of support and the trim finishing off the opening in the ceiling or wall surface shall be permitted to be in contact with combustible materials.
(2) Type IC. A recessed luminaire that is identified for contact with insulation, Type IC, shall be permitted to be
in contact with combustible materials at recessed parts, points of support, and portions passing through or finishing off the opening in the building structure.
(B) Installation. Thermal insulation shall not be installed above a recessed luminaire or within 75 mm (3 in.) of the recessed luminaire's enclosure, wiring compartment, or ballast unless it is identified for contact with insulation, Type IC.
410.117 Wiring.
(A) General. Conductors that have insulation suitable for the temperature encountered shall be used.
(B) Circuit Conductors. Branch-circuit conductors that have an insulation suitable for the temperature encountered shall be permitted to terminate in the luminaire.
(C) Tap Conductors. Tap conductors of a type suitable for the temperature encountered shall be permitted to run from the luminaire terminal connection to an outlet box placed at least 300 mm (1 ft) from the luminaire. Such tap conductors shall be in suitable raceway or Type AC or MC cable of at least 450 mm (18 in.) but not more than 1.8 m (6 ft) in length.
XII. Construction of Flush and Recessed Luminaires
410.118 Temperature. Luminaires shall be constructed such that adjacent combustible material is not subject to temperatures in excess of 90°C (194°F).
410.120 Lamp Wattage Marking. Incandescent lamp lu- minaires shall be marked to indicate the maximum allowable wattage of lamps. The markings shall be permanently installed, in letters at least 6 mm ('/»in.) high, and shall be located where visible during relamping.
410.121 Solder Prohibited. No solder shall be used in the construction of a luminaire box.
410.122 Lampholders. Lampholders of the screw shell type shall be of porcelain or other suitable insulating materials. Where used, cements shall be of the high- heat type.
XIII. Special Provisions for Electric-Discharge
Lighting Systems of 1000 Volts or Less
410.130 General.
(A) Open-Circuit Voltage of 1000 Volts or Less. Equip- ment for use with electric-discharge lighting systems and designed for an open-circuit voltage of 1000 volts or less shall be of a type identified for such service.
(B) Considered as Energized. 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.
(C) Transformers of the Oil-Filled Type. Transformers of the oil-filled type shall not be used.
(D) Additional Requirements. In addition to complying with the general requirements for luminaires, such equipment shall comply with Part XIII of this article.
