A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

The power distribution board is equipped with fuses and miniature circuit breakers (MCBs and MCCBs) that prevent permanent electrical damages to connected devices and wirings from risks like circuit overloads and power surges during electrical anomalies.

A power distribution board is not just a simple box but a complex assembly of components that work together to ensure safe and efficient electricity distribution. Each component is crucial, from the power source connection to circuit protection, control, and monitoring.

2025年1月6日 · What is a Power Distribution Board and How Does It Work? A power distribution board (DB) is an essential electrical panel containing circuit breakers, fuses, and other safety components to distribute electricity safely throughout a building’s various circuits.

2025年2月13日 · Let’s explore the above 10 types of distribution boards one by one. 1. Main Distribution Board (MDB) The Main Distribution Board (MDB) is the powerhouse of your electrical system. It acts as the central hub where electricity is distributed to various circuits in a building. Think of it as the main artery of your electrical network.

2023年1月30日 · A distribution board or distribution panel (DP) is an important part of an electricity supply system. Its job is to split an incoming electrical power feed into multiple secondary or subsidiary circuits.

DB Panels play a vital role in ensuring efficient power distribution within an electrical system. They help in managing the power supply and regulating the voltage to different devices and circuits. This results in optimized power usage, reduced energy wastage, and lower electricity bills.

Power Distribution board is used for controlling of utilization of power in the end point as lighting, power circuit and other equipment as TV, fridge and airconditioning.

Power Distribution Boards (PDBs) These are designed to distribute the power to various machines and equipment, even in big building we can observe such arrangement of power distribution through PDBs. PDBs are built with short circuit as well as overload protection systems.

2025年2月27日 · It doesn’t distribute power like a distribution board. Size. Distribution boards are bigger in size and are built to handle higher power loads. You can use these boards in industrial or commercial settings as they can manage complex electrical systems. They can contain multiple circuit breakers while ensuring proper power distribution and ...
