This is an assembly of electro-conductive parts consisting of miniature circuit breakers(MCB) of various ratings,isolator switch,bus-bars,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 cables and apparatus.
Distribution boards are used in household, commercial and industrial installations for distributing of power to final sub-circuits e.g. lighting for cable entries, They could be surface-mounted or flush-mounted with removable cover and breakable inlet 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 sizes of the circuit MCB depends on the rating of the final sub-circuits. |
