These centres generally comprise of power control devices, bus chambers, switchgear chambers, cable alleys, control bus chamber, control wiring and protective relays and devices. The switching centres in industrial power distribution are usually classified as (i) Power Control Centres (PCC) (ii) Motor Control Centres (MCC) (iii)Power and Motor Control Centres(PMCC) (iv) Fuse Distribution Board (FDB) In small installations, the switching centres are designated as Main Switch Board (MSB), Sub Switch Boards (SSBs) and Fuse Distribution Boards (FDBs).High voltage switching centres are generally classified according to the level of voltage whereas medium voltage switching centres are classified on read more
