Wiring of recessed luminaires (see Appendix B)
1) The temperature rating of insulation of conductors other than branch circuit conductors used to connect recessed luminaires shall comply with the conductor temperature rating marked on the luminaire.
2) The temperature rating of insulation of the branch circuit conductors run directly to the luminaire shall be in compliance with the insulated conductor temperature rating marked on the luminaire.
3) Tap connection insulated conductors shall be installed in a raceway extending at least 450 mm but not more than 2 m from the luminaire and terminated in an outlet box conforming to Subrule 4).
4) The outlet box referred to in Subrule 3) shall be
a) accessible as required by Rule 12-3014;
b) located not less than 30 cm from the luminaire; and
c) located within 35 cm from an opening intended for access.
5) Where access to the outlet box referred to in Subrule 4) is through the opening for mounting the luminaire, this opening shall not be less than a circle of 180 cm2, with no dimension less than 15 cm.
6) Where the luminaire opening referred to in Subrule 5) is smaller than 15 cm in any direction, access to the outlet box referred to in Subrule 4) shall be through some other opening not less than a square or rectangle of 400 cm2, with no dimension less than 20 cm.
7) A supply connection box that is an integral part of the luminaire shall
a) be accessible in accordance with Rule 12-3014; and
b) if access is through the opening for mounting the luminaire, meet the following requirements:
i) the electrical components of the luminaire shall be capable of being extracted through the opening for service, and the components shall include ballasts, transformers, thermal protectors, and conductor connections in the supply connection box; and
ii) the cover of the supply connection box shall be capable of removal by hand tool, held below the ceiling.
8) A supply connection box that is an integral part of the luminaire shall not have insulated branch circuit conductors pass directly through the junction box unless the luminaire is marked as suitable for the purpose.
