What is a Sub Distribution Board (SDB)?

A Sub Distribution Board (SDB) is an electrical panel that receives power from the Main Distribution Board (MDB) and further distributes it to specific areas, circuits, or loads. SDBs play a crucial role in organizing and managing power distribution efficiently while ensuring safety and ease of maintenance.



Key Features of SDBs

Reliable Power Distribution – Effectively distributes electricity to various sections of a building or facility.
Enhanced Safety Measures – Equipped with circuit breakers, fuses, and surge protectors to prevent electrical hazards.
Modular & Scalable Design – Can be customized and expanded to meet future electrical demands.
Easy Installation & Maintenance – Designed for quick access and hassle-free servicing.
Compliance with Global Standards – Built according to IEC, UL, and other international safety regulations.
Energy Efficiency – Helps in reducing power losses and optimizing energy consumption.



Types of Sub Distribution Boards

🔹 Single-Phase SDBs – Designed for small residential or office applications.
🔹 Three-Phase SDBs – Ideal for industrial and commercial buildings requiring higher power capacity.
🔹 Wall-Mounted SDBs – Compact and space-saving solutions for limited spaces.
🔹 Floor-Standing SDBs – Used for larger facilities needing multiple circuits and higher power distribution.
🔹 Weatherproof & Outdoor SDBs – Built to withstand harsh environments for outdoor applications.



Components of an SDB

Incoming Circuit Breakers (MCB/MCCB) – Protects the panel from overcurrent and short circuits.
Outgoing Circuit Breakers – Distributes power to different loads and sub-circuits.
Busbar System – Ensures efficient and reliable power conduction within the panel.
Surge Protection Devices (SPDs) – Safeguards electrical systems from voltage surges and spikes.
Energy Meters & Monitoring Devices – Tracks power usage and helps in efficient energy management.
Neutral & Earth Busbars – Provides proper grounding and electrical safety.
