This is an assembly of electro-conductive parts consisting of miniature circuit breakers (MCB) of
various ratings. Isolator switch, bus-bas, neutral & earth bars, all enclosed in a steel metal case for
circuits of single-phase or three-phase.
They contain equipment for protecting, switching and controlling and controlling cables and
apparatus.
Distribution boards are used in private, commercial and industrial installations for distribution of
power to final sub-circuits e.g. lighting circuits and small rated power circuits.
They could be surfaced mounted or flushed mounted with removable cover and breakable inters
on both top and bottom sides for cable entries. Every final sub-circuit is connected to one way of
the Distribution board via the MCB. The size of the circuit MCB depends on the rating of the final
sub-circuits.
