Distribution Boards

A distribution board, also known as a panel board or consumer unit, is a vital component of any electrical system. Its primary role is to receive power from the main supply and safely distribute it to individual circuits throughout a building. Typically located near the main electrical feed, every property will have at least one distribution board.

The size and configuration of a distribution board depend on the total electrical load and the number of circuits required. Inside the enclosure, key components include the main switch, circuit breakers, earth leakage devices, and bus bars—all working together to protect against overloads, short circuits, and earth faults.

Distribution Board Types & Features

• Main Switch Units – Simple isolation for entire installations.
• Dual RCD Units – Split protection for safer fault management.
• High-Integrity Units – Flexible configuration with dedicated RCBO circuits.
• 3-Phase Boards – Designed for industrial and commercial three-phase systems.
• Improved Safety - Safety is one of the main benefits of using a distribution board. Using one ensures that your electrical supply is evenly distributed to each circuit. This, in turn dramatically reduces circuits being overloaded resulting in one circuit shutting down your whole system.
• Electrical Phase – Single-phase for domestic, three-phase for commercial/industrial.
• Maximum Current Rating – Typically ranges from 63A to 125A+.
• Number of Ways – Indicates circuit capacity; options range from 4 to 24+ ways.
