Sub Main Distribution
Board (SMDB):

Sub Main Distribution Board (SMDB) is an integral component of an electrical power distribution system, typically used in larger facilities where power needs to be distributed across different areas or sections. The SMDB acts as an intermediary between the Main Distribution Board (MDB) and the final circuit breakers or loads.

Components:

Incoming Circuit:
- Main Circuit Breaker: Provides protection and isolation for the entire SMDB, usually connected to the MDB or another upstream distribution board.
- Busbars: Copper (Purity 99.98%) strips that conduct electricity from the incoming power supply to various circuits within the SMDB. Busbar size based on the load.
Outgoing Circuits:
- Circuit Breakers: Protect each outgoing circuit, similar to those found in the MDB, designed to prevent overloads, short circuits, and other electrical faults.
- Residual Current Devices (RCDs) or Residual Current Circuit Breakers (RCCBs): Optional protection devices that safeguard against earth faults.
Monitoring Devices:
- Meters and Indicators: May include energy meters, voltage and current indicators, to monitor power consumption and system health at the SMDB level.
Enclosure:
- Protective Housing: Often made of metal, designed to protect the internal components from environmental factors and unauthorized access, with appropriate IP ratings.
- Metal enclosure made from 2mm for structure and 1mm doors and cover from.

- Powder coated with the RAL color 7035 /7032. Any other color on request.
Earthing System:
- Earthing Busbar: Ensures all components within the SMDB are properly grounded for safety.

Functionality:

Intermediate Power Distribution: The SMDB acts as a distribution point between the MDB and final distribution points (like lighting panels, socket outlets, or specialized equipment), enabling efficient power distribution to various sections or floors of a building.
Enhanced Protection: Provides additional layers of protection by segmenting the electrical distribution into smaller, more manageable sections. Each section can be isolated or protected independently.
Load Management: Allows for better load management and distribution, which is particularly important in large facilities with diverse and fluctuating power demands.
System Flexibility: Facilitates expansion and modification of the electrical system, making it easier to add new circuits or redistribute loads without affecting the entire network.

Applications:

Commercial Buildings: In multi-story buildings, SMDBs are often installed on each floor to manage power distribution from the MDB to specific areas or rooms.
Industrial Plants: Used to distribute power to different sections of the facility, such as production areas, administrative offices, or specific machinery.
Large Residential Complexes: SMDBs may be used to distribute power from the main board to different wings, floors, or sections of the complex.
Infrastructure Projects: In large infrastructure projects like airports, hospitals, or shopping malls, SMDBs help manage the distribution of power to various zones or departments.

Importance:

Localized Control: Provides localized control and monitoring of electrical power, making it easier to manage, maintain, and troubleshoot specific sections of a facility.
Safety and Reliability: Enhances the safety and reliability of the electrical distribution system by preventing faults in one section from affecting the entire system.
