Sub Main Distribution Board (SMDB)

TECO GROUP designs and manufactures sub main distribution boards (SMDB) that distribute power from the main distribution board (MDB) to individual floors, wings, departments, or process areas within a facility. Every SMDB is engineered and assembled in our own production facility — available in wall-mount or free-standing configurations with forms of separation up to Form 4B, type tested to IEC 61439 and design verified for safe, reliable secondary power distribution.

Our sub main distribution board capabilities include:

• Type tested assemblies to IEC 61439 — design verified for compliance and safety.
• Wall-mount enclosures with custom busbar or pre-fabricated tinned busbar systems for compact installations.
• Free-standing enclosures with forms of separation up to Form 4B using Ri4Power technology for enhanced operator safety and maintainability.
• Rated current configurations tailored to project requirements — from small floor-level boards to high-capacity zone distribution panels.
• Integration with automatic transfer switches (ATS) for essential and non-essential load segregation in hospitals and critical facilities.
• Coordination with upstream MDB and downstream final distribution boards (FDB) for complete power distribution hierarchy.
• Full factory testing including insulation, high voltage, and functional verification before dispatch.
