What is the meaning of main switch board?

A main switchboard is a large electrical distribution board that receives power from the main power supply and distributes it to various circuits and electrical systems within a building or facility. It typically contains switches, circuit breakers, and other protective devices to control the flow of electricity and ensure the safety of the electrical system. The main switchboard is a critical component of the electrical infrastructure in a building and is responsible for distributing power to all the electrical loads within the facility.

A main switchboard is a part of an electrical distribution system which serves as the central point for the distribution of electricity to various circuits within a building or other structure. It is typically located in a dedicated electrical room or closet, and houses the main circuit breaker or fuse, which protects the entire electrical system from overcurrent conditions. The main switchboard also contains other components such as busbars, which are used to distribute power to the various circuits, and switches, which allow for the isolation of individual circuits for maintenance or repair purposes.
