Frequently asked questions

What is the difference between a DB and an SDB?

A DB is fed from the MDB and serves a floor or section. An SDB is fed from a DB and serves a smaller area, such as a flat or a group of machines.

Do I need an RCCB in my DB?

For areas where people may touch equipment, such as homes, offices and wet areas, earth leakage protection is strongly recommended.

Can you supply DBs with branded breakers?

Yes, with genuine ABB, Schneider Electric, Siemens or Mitsubishi breakers.
