BS 8488 prescribes the applicable standards for the
assembly containing couplers intended for the through
connection of circuits that emanate from separate overcurrent
protection e.g. circuit-breakers. One example of this
arrangement is a multiple circuit distribution cable (known as
a home run) originating from a distribution board and
terminating at an assembly of couplers (known as an Area
Distribution Box “ADB”) (see figure 9).
Depending upon the configuration of the assembly of
couplers for through connection, BS 8488 requires
conformity with BS 5733 or the relevant part of BS EN 60439,
BS EN 61439 or BS EN 61534.
