Sub Main Distribution Board (SMDB)

Sub-distribution boards fed by the MDB, installed where a large distribution cable ends and smaller sub-circuits begin.

The MDB feeds SMDBs, which are generally installed at the point where a large distribution cable terminates and several smaller sub-circuits begin. These switchboards, although similar in construction to the MDB, are larger than a final distribution board. They are installed midway through the power distribution system, where a large distribution cable ends and several smaller sub-circuits start.
