1. Understanding the Role of Electrical Distribution Boards
An electrical distribution board, also known as a panel board or breaker panel, acts as the control hub for electrical circuits in a facility. It routes electricity from the main power source to individual branch circuits, ensuring safe power delivery while housing protective devices such as MCBs (Miniature Circuit Breakers), MCCBs (Molded Case Circuit Breakers), and RCCBs (Residual Current Circuit Breakers).
These boards help prevent hazards such as overloads, short circuits, and equipment damage. Their centralized configuration also simplifies fault identification and rectification, making them indispensable in power system architecture.
2. What Is an AC Distribution Board?
An AC distribution board specifically manages alternating current power, which is the standard for most residential, commercial, and industrial setups. Unlike general electrical boards, AC distribution boards are engineered to handle varying AC voltages, loads, and frequencies.
Core Functions:
- Split the incoming power supply into subsidiary circuits
- Integrate safety and monitoring devices
- Facilitate phase-wise control and protection
The size and complexity of the application will determine whether these boards are integrated into switchgear assemblies, mounted on the wall, or mounted on the floor.
3. Low Voltage Switchgear: A Key Component
Low voltage switchgear operates at voltages below 1,000V AC and is often embedded within distribution boards. It includes components such as:
- Contactors and relays
- Circuit breakers (MCBs, MCCBs)
- Busbars and terminal blocks
- Metering instruments and protective relays
Top low-voltage switchgear manufacturers offer highly modular and intelligent systems that enhance fault protection, automation, and system monitoring.
