The 3d design of switch board is drawn it is used to connect with electricity. The role of a switchboard is to allow the division of the current supplied to the switchboard into smaller currents for further distribution and to provide switching, current protection and (possibly) metering for those various currents. A switchboard operator works for major companies, hospitals, and hotels where an influx of telephone calls are normally coming in. The operator assists callers by answering the line and connecting the caller to the correct person or department. A distribution switchboard is the point at which an incoming-power supply divides into separate circuits, each of which is controlled and protected by the fuses or switchgear of the switchboard.
