What You'll Learn
Sub Main Distribution Boards (SMDB) are used to supply electricity to panels
Sub Main Distribution Boards (SMDB) are an extremely cost-effective way of reducing power cabling costs. They are generally installed at load centres and are sheet steel enclosed with powder coating in a cabinet (wall-mounted) or feeder pillar (floor-mounted) design. SMDBs are used to supply electricity to panels. They can be customised to user requirements and have ample space to facilitate cable termination.
SMDBs are suitable for both indoor and outdoor use and can be adapted to the available location. They are often used in conjunction with Power Distribution Boards (PDB) or Main Distribution Boards (MDB), which have a main incomer of up to 2500A or 4000A and various outgoing feeders. The PDB or MDB can be designed with suitable cable alleys to terminate cables from the top, bottom, or sides.
The electrical wiring within an SMDB distributes current from a single source of supply to various circuits. These circuits are arranged inside an enclosure, which is typically made of sheet steel with a powder coating. This enclosure can be customised to the user's needs and can be mounted on a wall or floor, depending on the design.
SMDBs are an essential component of electrical systems, particularly in managing and distributing power to panels and other equipment. They offer a flexible and cost-effective solution for a range of applications, from industrial automation to energy auditing. By using SMDBs, users can benefit from reduced cabling costs and a more efficient power distribution system.

SMDBs are economical for reducing power cabling costs
SMDB stands for Sub Main Distribution Board. It is a type of distribution board, which is an enclosure that houses the arrangement of circuits in electrical wiring that distributes current from a single source of supply to various circuits.
SMDBs are extremely economical for reducing power cabling costs. They are generally installed at load centers and are made of sheet steel enclosed in a powder coating with a cabinet or floor mounting design. This provides ample space for cable termination and can be customized to user requirements.
The use of SMDBs can help to reduce the amount of cabling needed, as they serve as a junction for multiple electrical devices. This not only reduces the material costs associated with cabling but also the labor costs of installation. SMDBs can also be designed for either indoor or outdoor use, providing suitable protection for the specific environment.
Additionally, SMDBs can be designed with a wall-mounting or floor-mounting option, depending on the user's needs. This flexibility in installation can further reduce cabling costs, as the most efficient and effective method of installation can be utilized.
Overall, SMDBs offer a cost-effective solution for power distribution, especially in terms of reducing cabling costs. Their customizable and flexible nature makes them a versatile option for a range of applications and helps to keep installation and material expenses to a minimum.

They are generally installed at load centres
Sub Main Distribution Boards (SMDB) are extremely cost-effective for reducing power cabling costs. They are generally installed at load centres, which are used to distribute electricity supplied by the utility company throughout a home or building. Load centres are also known as fuse boxes, breaker boxes, panel boards or distribution panels. They are typically located in the garage, basement or outdoors depending on the geography.
Load centres are used in residential and light commercial applications. In residential settings, load centres distribute power inside the home, with each branch circuit protected by a circuit breaker housed in the load centre. In light commercial buildings, load centres provide power distribution in buildings such as strip malls, office buildings and warehouses.
Load centres have a wide range of applications, from single-family homes to original equipment (OEM) products. They range from 40-600 amps and 2-120 circuits. Residential single-family homes typically have one or more load centres to distribute power. Residential multi-family apartments, condominiums and townhomes commonly use load centres to distribute power, usually installed within group metering products.
Load centres can be equipped with a main breaker or main lug only (MLO) design. In a load centre with a main breaker design, the incoming supply cables are connected directly to the main circuit breaker. Load centres can be customised to meet unique needs, with interiors available in single-phase or three-phase and a variety of circuit configurations and amp ratings.

SMDBs are sheet steel enclosed with powder coating
SMDB stands for Sub Main Distribution Board, which is an extremely economical way of reducing power cabling costs. They are generally installed at load centres and are sheet steel enclosed with powder coating.
Powder coating is a process where a polymer-based coloured powder is sprayed onto a metal surface, creating a protective and visually appealing finish. This process is done on sheet metal parts made from materials such as steel, aluminium, and stainless steel. The powder coating method is versatile and durable, making it suitable for various applications. It also provides a hard surface that resists corrosion and scratches, limiting the exposure of bare metal to environmental hazards.
To prepare sheet metal for powder coating, the parts are hung on a rack to ensure all surfaces are exposed to allow for a uniform coat. This can be achieved through existing holes in the metal or by drilling new holes. The powder coating process typically adds 0.002-0.004 inches of thickness to the metal, resulting in a smooth-to-the-touch glossy finish that is visually striking and upscale in appearance.
It is important to note that powder coating may not be suitable for geometries with extremely tight bend radii, small holes, or enclosed surfaces. Additionally, cavities can trap excess powder, creating an undesirable and inconsistent internal coating. Therefore, it is recommended to add vent holes to help excess powder escape.
Overall, powder coating sheet steel for SMDBs provides a durable, attractive, and versatile finish that is suitable for both indoor and outdoor use, offering ample protection from corrosion and scratches.

They are customisable to user requirements
Sub Main Distribution Boards (SMDB) are highly adaptable to the needs of the user. SMDBs are electrical distribution boards that are used to distribute current from a single source of supply to various circuits. They are extremely economical for reducing power cabling costs and are generally installed at load centres.
SMDBs are customisable to user requirements in a number of ways. Firstly, they can be designed for either indoor or outdoor use, with suitable protection for the specific environment. Secondly, SMDBs offer ample space for cable termination and can accommodate various electrical components such as MCCB/Switch/HRC fuses. This flexibility ensures that users can customise the board to their specific needs.
Additionally, SMDBs can be customised in terms of their physical design. They are typically sheet steel enclosed with a powder coating and can be designed for either cabinet (wall) mounting or feeder pillar (floor) mounting, depending on the user's requirements and the available space. The cabinet design can be tailored to suit the specific location and can be completed erected and commissioned on-site.
Furthermore, SMDBs can be customised to accommodate different electrical ratings. For example, the Power Distribution Board (PDB) and Main Distribution Board (MDB) offer a range of main incomer ratings from 250A to 4000A, with various numbers of outgoing feeders. This flexibility ensures that SMDBs can be customised to handle different electrical loads and circuit configurations.
Overall, the customisability of SMDBs makes them a versatile and user-friendly option for electrical distribution. By tailoring the board to their specific needs, users can optimise their electrical systems, reduce cabling costs, and ensure a safe and efficient distribution of power.
