This British Standard specifies requirements for luminaire supporting couplers (LSCs) comprising LSC plugs and LSC outlets for use in final circuits rated at not more than 16 A, where the supply voltage does not exceed 250 V a.c. and the electrical load connected to any one LSC plug does not exceed 6 A.
The requirements specified in this standard have particular reference to safety in normal use.
LSC outlets are intended for use with cables complying with BS 6004 or BS 6007, having copper conductors.
LSC plugs which are not integral with a luminaire are intended for use with flexible cords complying with BS 6141 or BS 6500, having a cross-sectional area from 0.5 mm2 to 1.0 mm2.
The standard is applicable to LSCs intended for either:
- the mechanical and electrical connection and disconnection of luminaires suspended by flexible cords up to a maximum supported load of 5 kg; or
- the mechanical and electrical connection and disconnection and direct mechanical support of luminaires, i.e. other than by a flexible cord.
The standard is not applicable to LSC plugs and LSC outlets intended to be used on extra low voltage (ELV) supplies.
NOTE 1 LSC outlets complying with this standard may be regarded as lighting outlets in accordance with the provisions of Appendix 4 of the 15th edition of the Regulations for Electrical Installations1).
NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
