Sub Distribution Board (SDB) – Secondary Power Distribution Panel
The Sub Distribution Board (SDB) is a secondary electrical panel designed to receive power from the Main Distribution Board (MDB) and safely distribute it to various localized circuits. Built with high-quality protective devices and durable enclosures, SDBs ensure safe load management, circuit isolation, and efficient power routing across residential, commercial, and industrial facilities.
Engineered to handle multiple outgoing feeders, these boards improve electrical safety, protect equipment from overload/short-circuit, and offer easy accessibility for maintenance.
