Sub Main Distribution Boards

Sub main distribution boards (SMDB) are also referred to as MCCB panels. A typical SMDB is equipped with MCCBs as incomer and MCCBs as outgoings. MCCB incomer is connected to upstream Main Distribution Board whereas MCCB outgoings are connected to downstream loads. These MCCBs wall mount with user friendly arrangements.
SMDBs are installed half way through the mains distribution system, generally at the point where a large distribution cable terminates, and several smaller sub-circuits start.
