Distribution board circuit breaker

A distribution board (also known as a panel board or breaker box) is an electrical panel that distributes power from the main electrical service to various circuits in a building. A circuit breaker is a device that is installed in the distribution board to protect the circuit from overcurrents and short circuits.

Here's a breakdown of the components:

Distribution Board (DB):

Circuit Breaker:

How it works:

  1. Power from the main electrical service enters the DB.
  2. The power is distributed to various circuits through the circuit breakers.
  3. Each circuit breaker is designed to interrupt the flow of current in the event of an overcurrent or short circuit.
  4. If an overcurrent or short circuit occurs, the circuit breaker trips, interrupting the flow of power to the affected circuit.
  5. The circuit breaker can be reset once the fault has been cleared.

Common applications:

In summary, a distribution board circuit breaker is an essential component of an electrical system that provides overcurrent protection and helps to prevent electrical faults and damage to equipment.
