Which type of switchboard is commonly used for electrical distribution in buildings?

A switchboard is a crucial component in electrical distribution systems, particularly within buildings. It serves multiple functions, including managing the distribution of electrical power from a single source to various circuits. Switchboards typically contain protective devices and fuses, as well as switches that allow for control over the flow of electricity.

In buildings, the switchboard is designed to accommodate multiple feeders and circuits, facilitating the efficient management of power supplies for various areas or equipment within the structure. This makes it suitable for applications where a higher level of power distribution and management is required, often found in commercial and industrial environments.

While the other options may play roles in electrical distribution, they serve more specific functions. For instance, an automatic transfer switch is utilized for switching between primary and backup power sources, primarily in emergency applications. A panel board is generally designed for low-voltage power distribution and typically serves a specific area or load within a building, while a distribution board is a more general term for equipment used to distribute electrical power. However, it’s the switchboard that best encapsulates the broader functionality and capacity needed for comprehensive electrical distribution in buildings.
