Distribution boards are an essential component of any electrical system, as they serve as the main point of connection between the incoming electrical supply and the various circuits within a building. There are different types of distribution boards available, each designed for specific applications. If you're not familiar with distribution boards, here are 10 questions you should know about their types.
**What is a Distribution Board?**.
A distribution board, also known as a breaker panel or electrical panel, is a metal box that contains the main switches, circuit breakers, and fuses that control the flow of electricity to different parts of a building.
**Main Types of Distribution Boards**.
There are three main types of distribution boards: main switchboards, sub-main distribution boards, and final distribution boards. Each type serves a specific purpose and is designed to meet the requirements of different types of installations.
**Main Switchboards**.
Main switchboards are the primary point of entry for the electrical supply into a building. They typically house the main switch, which controls the flow of electricity into the building, as well as any other necessary protection devices.
**Sub-Main Distribution Boards**.
Sub-main distribution boards are used to distribute power to different sections or floors of a building. They are connected to the main switchboard and serve as secondary distribution points within the building.
**Final Distribution Boards**.
Final distribution boards, also known as consumer units, are located at the end of the electrical distribution system. They provide power to individual circuits within a building, such as lighting, appliances, and outlets.
**Number of Ways**.
The number of ways refers to the number of circuits that a distribution board can accommodate. Distribution boards are available in various sizes, with a different number of ways to suit the specific requirements of an installation.
**Busbar Type**.
The busbar is a metal strip or bar that conducts electricity within the distribution board. There are different types of busbars, such as single-phase, three-phase, and neutral, depending on the electrical system's requirements.
**Enclosure Material**.
Distribution boards are typically housed in metal enclosures to protect them from dust, moisture, and other external factors. The enclosure material can vary, with options like steel, plastic, and fiberglass available.
**IP Rating**.
The IP rating, or Ingress Protection rating, indicates the level of protection that a distribution board offers against foreign objects and moisture. A higher IP rating means better protection against these elements.
**Surge Protection**.
Some distribution boards come equipped with surge protection devices to safeguard connected equipment from voltage spikes and electrical surges. Surge protection is essential in areas prone to lightning strikes or power fluctuations.
**Compliance with Standards**.
It is crucial to ensure that the distribution board you choose complies with relevant electrical standards and regulations. This ensures the safety and reliability of the electrical installation.
In conclusion, distribution boards play a vital role in ensuring the safety and functionality of electrical systems in buildings. By understanding the different types of distribution boards and their features, you can make informed decisions when selecting the right one for your installation.
