Connection to the fixed wiring
BS 7671 specifies the products that may be used to facilitate
connection to each fixed lighting point. A plug-in lighting
distribution unit to BS 5733 is identified as an appropriate
product, particularly in suspended ceilings, where one plug-in
lighting distribution unit may be used for a number of
luminaires.
Where a wiring system comprising of a single circuit
terminates at an assembly containing couplers intended for
branching of a circuit, the assembly is required by BS 8488 to
comply with specific standards depending on the
assembly designation. Where the assembly containing
couplers is specifically designated for the connection of
luminaires, it is classified as a lighting distribution unit and
must comply with BS 5733 (see figure 10).
