👉 A switchboard is a device used to control and monitor electrical circuits. It consists of several electronic components, such as switches, relays, and transformers, which are used to control power distribution in an electrical system. The main function of a switchboard is to allow for switching between different power sources or circuits, allowing equipment to operate at different voltages or currents. Switchboards can be found in various types of electrical systems, including residential, commercial, and industrial settings.
