Different Types of Distribution Boards

March 1, 2021

Almost 30 people die in India every day due to electrical hazards like a short circuit, earth leakage, electrocution and more. Besides people, there is also a loss of property and assets due to fire caused by these hazards, especially during the monsoon season. Since so many activities occur here, they have to be safe and protected from any hazards at all times.

Power Distribution system panels are installed when the main power will flow through the building and distribute into the other various circuits to provide electricity to the numerous consumption points in the building.

Components of Distribution Board

The distribution board system includes various elements like contact breakers, earth leakage units, doorbells and timers. It’s primary focus is to make sure the electrical power is distributed all over the building in equal quantity. Since it is in charge of power transmission, it is essential to select the right one for yourself.

They are quite versatile. Many people buy the empty enclosures and according to their needs, customise it and wire it. You can also have the board separate for different parts of your building. So you could be using one electrical panel for your gym and pool area and other for your residential or living area.

As long as the switch disconnector controls each board, you can have separate ones depending on your electrical requirements.

While choosing a board for your building, make sure you know the various distribution boards before opting for one.

Types of Distribution Board

1.   Fuse Boxes

A fuse box is a space where you’ll find all the electricity is transmission and distribution. In the case of an emergency like a short circuit, you should know the fuse box’s location. In these situations, you should turn it off as soon as possible to keep it from getting worse.

They contain three components – main switch, circuit breakers and residual current device.

2.   Main Breaker Panels

Being the most common distribution board, you’ll find the main breaker panel everywhere. It protects the circuits from overheating and keeps an eye on the panel’s amperage capacity.

Incidentally, given its function, the main breaker panel can cut power to the house, including the circuit breakers.

3.   Main Lug Panels

They are mostly used as distribution boards when there is a main breaker upstream. Line wires pass through these panels and can be used as a sub-panel when connected with the main panel breaker.


It helps cut the power generation flow at the meter so that it doesn’t enter the house at all during emergencies.

4.   Subpanels

These are highly recommended for households as they are comfortable and safe to install. They are also very small and help in power distribution to specific parts of your house or area.

They work efficiently and are known as satellite circuit breaker panels. They, however, do not have disconnects.
