Sub Main Distribution Board (SMDB)
A sub-main distribution board (SMDB) is a device that distributes electrical power from the main distribution board (MDB) to various building areas. It is typically located in a central location within the building and serves as a secondary point of distribution for electrical power.SMDBs are designed to safely and efficiently distribute electrical power to different areas of a building or facility. They typically consist of a metal enclosure containing various electrical components, such as circuit breakers, fuses, and switches, used to control and distribute the electrical power.
The SMDB receives electrical power from the MDB and distributes it to various circuits within the building through a network of electrical wires and cables. The panel may also include indicators, such as lights or gauges, to display the status of the electrical system or the panel itself.
In addition to distributing electrical power, SMDBs also protect against electrical hazards, such as overloading and short circuits. They may be equipped with safety features such as ground fault circuit interrupters (GFCIs) and overload protection to help prevent electrical shocks and damage to the electrical system.
Here’s how we work
The SMDB is equipped with a main breaker or main disconnect, a switch that can shut off all the electricity in the panel. In an emergency or when the repair needs to be done, the main breaker or main disconnect, which is normally found at the top of the panel, is used to cut off power to the panel from the MDB.

4 The power from the MDB is fed into the panel through incoming wires and then distributed to the various circuits in the building through outgoing cables.
FAQs
What is a sub-main distribution board (SMDB)?
A sub-main distribution board (SMDB) is a type of electrical panel used to distribute power to a building’s specific area or circuits. It is connected to the main distribution board (MDB) for the establishment and typically contains circuit breakers or fuses that protect the circuits from overcurrent and short courses.
How does a sub-main distribution board (SMDB) work?
The SMDB receives power from the building’s main distribution board (MDB) and uses circuit breakers or fuses to control and distribute the power to the various electrical circuits in the area or group it serves. If an overcurrent or short circuit occurs, the circuit breaker or fuse will trip, breaking the electrical connection and preventing damage to the wiring and other electrical components.
What is the difference between a main distribution board (MDB) and a sub-main distribution board (SMDB)?
A main distribution board (MDB) is the main electrical panel for a building and is used to distribute power to the various subpanels and circuits in the building. A sub-main distribution board (SMDB) is a secondary electrical panel connected to the main panel and used to distribute power to a specific area or group of circuits in the building.To learn more about SMDB maintenance services,contact us
How to maintain a sub-main distribution board (SMDB)?
To maintain a sub-main distribution board (SMDB), following the manufacturer’s recommended maintenance and repair procedures is essential. It may include regularly cleaning the panel and its components, checking for and repairing any damaged or worn parts, and testing the board to ensure it is functioning correctly. Protecting the SMDB from environmental hazards such as moisture, dust, and extreme temperatures is also important.
What is the primary function of a Sub Main Distribution Board?
The primary function of an SMDB is to distribute electrical power to different areas or zones within a building. It helps in regulating and controlling the flow of electricity, ensuring a safe and organized distribution to various electrical loads.
What components are typically found in a Sub Main Distribution Board?
An SMDB usually consists of circuit breakers, fuses, busbars, and other protective devices. These components work together to ensure a safe and controlled distribution of electrical power to different circuits.
Why is it important to have a Sub Main Distribution Board in an electrical system?
Having an SMDB is crucial for efficient power distribution and for managing electrical loads within a building. It helps prevent overloads, ensures a balanced distribution of power, and facilitates easier maintenance and troubleshooting.
What safety measures should be taken with Sub Main Distribution Boards?
Safety is paramount when dealing with electrical systems. Always ensure that qualified electricians install and maintain SMDBs. Regular inspections, proper labeling, and adherence to electrical codes and standards are essential for the safe operation of Sub Main Distribution Boards.For more your electrical service,lets touch with the Switchgear solutions.
What are SMDB Maintenance Services?
The SMDB Maintenance Services include inspection, testing, cleaning, and repairing Sub Main Distribution Boards. These steps are taken to ensure effective power distribution, thus preventing any electrical problems from arising. Regular maintenance can be very handy to detect possible faults and ensure reliable systems.
Why is regular SMDB Maintenance Services necessary?
Regular SMDB Maintenance Services provide the safety and efficiency of electrical systems. It prevents any type of electrical failure, reduces the time taken down to zero, and also increases the life of the equipment.
