Distribution Board: Features and its Types


A Distribution board, also known as an electric panel, is a building’s prime supply system. It separates the current into separate routes by giving a safety fuse or breaker. It ensures that the fuse should not allow excessive current to flow through the circuit. For example, When charging portable devices with sockets with USB ports, the battery is protected against explosion.


  • Almost every house or building will have at least one distribution board installed and placed where the main electrical line enters the structure. It ensures enough room for other wiring and cables.
  • Circuits and supply quantity determine the size of the board. It should be simple to mount and resistant to water and corrosion.
  • They are available as vacant containers, readily available electrified basic units or custom-made units based on the user’s requirements. It uses reliable methods to confirm the highest standards of wiring.

Based on the requirements, the distribution board is classified into the following types:

1. Main Breaker Panel

  • It protects circuits and keeps track of their current capacity.
  • It can chop the power of the complete house with the circuit breakers in the event of a short circuit. They safeguard the circuits from overheating. For example, Some low-cost or unbranded items that use sockets with USB ports may provide a danger of electric shock or fire.

2. Fuse Boxes

  • It controls and distributes all power supply.
  • They consist of three segments: the primary switch, circuit breakers, and a residual current device.

3. The main connector panel

  • When a main upstream breaker trip occurs, this panel is employed.
  • Line wires enter this connector, and when coupled to a switch from the panel board, the primary stud panel may be utilised as a sub-panel.
  • Meters can be turned off independently during an emergency. It will then act as the primary breaker, cutting off the electrical supply before everything enters the building.

4. Sub-panels

  • They are simple to install, have no connecting issues, and are efficient for houses.
  • They are connected to the primary panel by a circuit.
  • They are smaller and help provide electricity to a specific area acting as a remote circuit breaker panel.
  • They can modify the current distribution throughout the region or property.

5. Transfer switches

  • It moves the burden between electrical conductors sources.
  • They are ideal for backup power sources since they convert generator output to the electricity supply via the breaker panel.
  • The goal is to have the highest quality switchboard connection with a continuous power supply and safety.
  • They are helpful as alternative power generators in areas where the weather is unpredictable.
  • They are of two types: Manual Transfer Switches and Automatic Transfer Switches.


Thanks to the distribution board, all your electrical connections can run safely throughout the entire portion of land or building. Its role is to keep the facility and its occupants safe and distributes current throughout the region.
