Electrical SDB stands for Sub Distribution Board. It's a crucial component of an electrical distribution system within a building.
Here's a breakdown:
-
Function: An SDB is a subsidiary board connected to the Main Distribution Board (MDB). Its primary function is to distribute electrical power to a specific section or area within a building. Think of it as a smaller, localized distribution point.
-
Hierarchy: Electrical power flows from the utility company to the main switchboard, then to the MDB, and finally, to the SDBs before reaching individual circuits and equipment.
-
Purpose: SDBs enhance safety, improve maintainability, and allow for better control over the electrical supply to different building zones. This localized distribution allows for easier isolation and troubleshooting during maintenance or faults.
-
Key Benefits:
- Localized Control: Enables isolation of specific areas without affecting the entire building's power supply.
- Enhanced Safety: Facilitates safer maintenance and repairs by allowing technicians to de-energize only the affected circuits.
- Improved Efficiency: Optimizes power distribution by reducing voltage drop and cable lengths to individual loads.
- Easier Fault Finding: Simplifies troubleshooting by segmenting the electrical system into manageable sections.
In essence, an SDB is a smaller distribution board that branches off from the MDB to provide power to specific sections of a building, offering more control and improved safety.
