Components of Electrical Distribution Boards

Have you ever stared at the switchboard, plugged in your charger and wondered where does the electricity come from? How does this whole thing work? The working principle of a board can be an interesting one.

The various components that it has all work together in sync to provide you with power. It comprises multiple elements like contact breakers, earth leakage units, timers and so on.

An electrical board comes up to form an integral part of the electric installation- whether a residential or official building. It ensures that the power is equally distributed and the entire building gets a supply of power through the main feeding cable. The cable also helps in transporting the power from the electrical network to the building, which is all connected through the electrical board.

Components of Distribution Board

The distribution board comprises a special circuit breaker which is one of the essential elements of the panel. It is responsible for splitting the total amount of high-voltage electric power that the board receives into other mini circuit breakers.

These mini breakers are then further connected to cables that further divide the power into individual outlets, machine point or light circuit. The distribution board also has these cables but are located on the opposite side of the main feeding cable. The main aim of it is power transmission.

The board comprises:

  1. A control panel for mounting the incoming supply circuit breaker
  2. A distribution panel for housing the MCBs or fuse units, etc.
  3. Installation accessories like DIN rails, earth bars, and fixing conductors
  4. Service cable ducts or conduits

You can modify the electrical board according to your needs. According to your building’s requirements, an expert can study your requirements and suggest the best for you.

Besides this, other components that are included in an electric board are-

  1. bus bar
  2. fuse-links
  3. switches
  4. bypass equipment
  5. residual current detector

The bypass equipment is a mix of unique protection components. It helps in protecting the electrical connections within the board from electrical hazards like short-circuits, power overloading and more.

The Residual current detector helps in providing protection against fire and ground fault shock.

Since each distribution board is created to specific needs, the structural elements of it may vary.

You will pose a severe threat to your loved ones if you add or replace new components to your distribution board which are not tested or approved. This may also harm your electronic system.

While installing your electrical board, make sure it is at a height that the operating switches, indicating dials are all seen and accessible to the electrician. Heights are generally suggested around 1 meter and 1.80 meters from the floor. In the case of handicaps or older people, it may also by 1.30 meters. It varies as a rule from country to country.

So next time you plug in your electronic devices, you’ll know-how has the power reached to your electric device.
