An electrical switchboard is a device which directs electricity from one source to other. It is a congregation of panels, each of that includes switches which lets electricity to be redirected. The function of a switchboard is to separate the major current offered to the switchboard into minor currents for additional distribution and for providing current protection, switching and metering for a variety of currents. Generally, switchboards allocate power to transformers, control equipment, panelboards, and eventually to system loads.
Modern switchboards are metal enfold and of “dead front” construction; no energized parts are available as the panels and covers are closed. Previously, open switchboards were prepared with switches and other devices were escalated on panels, which are made of granite, slate, or ebony asbestos board. The metal field of the switchboard is connected to earth ground for the defense of workers. Large switch boards might be free-standing floor-mounted fields with condition for incoming associations at either the bottom or of the enclosure.
