Distribution Boards: Everything You Need To Know

460 0

An integral part of every electrical supply system is the distribution boards, often known as an electrical panel, breaker panel, or panel board. A DB is a type of electrical enclosure that houses a circuit breaker or fuse for each circuit and allows for the separation of a single electrical supply into multiple sub-circuits. 

Distribution boards are used to distribute the main supply cable to circuit breakers and, eventually, to each circuit or switch board within the building.

What is a Distribution Board?

A distribution board, often called a distribution panel (DP), is a crucial component of any electrical grid, and it divides a primary electrical circuit into several secondary or tertiary branches. Often, a fuse or circuit breaker will be installed to secure each of these auxiliary circuits.


The main switch board, bypass equipment, circuit breakers, earth leakage unit, bus bars, and sometimes additional switches are often on a power distribution board. All of this work together to protect the electrical distribution system and the electrical equipment attached to it from being harmed by faults like short circuits, overloads, earth leakage, etc. 

Electric distribution boards may have varying technological and structural qualities depending on local regulations.


Distribution boards come in a wide variety of styles and sizes nowadays, depending on factors such as the number of circuits (which manufacturers typically refer to as the number of ways or modules) rewired within the board, whether it be horizontal or vertical orientation, whether the doors are solid or made of see-through plastic, and so on. Getting a DB professionally installed is recommended for optimal performance, efficiency, and safety in any structure.


Distribution boards are typically installed in inconspicuous, out-of-the-way places like the basement, garage, or even beneath the stairs due to their ugly design and possibly for safety reasons. However, careful consideration must be given to its placement before installing a distribution board. 

It is important that the area where the distribution board will be installed has adequate ventilation to prevent the consumer unit from overheating and that the mains can be quickly shut off in case of a short circuit or fire.


While their essential function of efficient power distribution has remained the same, distribution boards have evolved in appearance and design with the always-developing technology. 

Distribution boards are now available in various beautiful designs engineered to perfection using cutting-edge technology, so there is no longer any need to conceal them behind that box or keep them out of sight. Instead, you can have them in a design that shows off your artistic side.


Distribution boards ensure the safe operation of all electrical appliances throughout the building. For instance, if you only need to power a single room in the building, you can put a 15-amp circuit breaker in the main panel. 

Legrand’s selection of distribution boards is designed to complement a variety of contemporary decors thanks to a wide variety of available colours, finishes, and styles. Legrand distribution boards are built to last and look great while meeting all your electrical needs.
