Maxell Sub Main Distribution Board (SMDB)
- These are distribution boards which although similar construction, are larger than a final circuit distribution boards.
- The boards 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.
- The board may be fitted with HRC fuses, MCB’s or MCCB’s. It may hence take the form of a large fuse board or and LV panel board.
