What is the role of the main distribution board in an electrical installation?

The main distribution board plays a crucial role in an electrical installation by distributing electrical power from the utility supply to various circuits within a building. Its primary functions include managing the flow of electricity, ensuring that circuits receive the appropriate amount of power, and providing overcurrent protection. Overcurrent protection is essential to safeguard electrical circuits from damage due to excessive current, potentially preventing electrical fires and equipment failure.

The distribution board achieves this by housing circuit breakers or fuses that automatically disconnect the electricity supply when excessive current is detected. This protective function is vital in maintaining both the safety and integrity of the electrical system as it mitigates risks associated with overloads and short circuits.

By effectively distributing power, the main distribution board also allows you to manage different electrical loads across various areas of a building, ensuring that the electrical system operates efficiently and reliably.
