A wiring diagram of a ship is a simplified conventional pictorial representation of an electrical circuit. A wiring diagram usually provides information about the relative positions and settings of devices and terminals on the device, to assist in building or servicing the device. This is not like a schematic diagram, where the arrangement of the interconnect components in the diagram is usually incompatible with the physical location components in the finished device. A pictorial diagram will show more details of the physical appearance, while the wiring diagram uses a more symbolic notation to emphasize the interconnection of physical appearance.
A wiring diagram is often used to solve problems and ensure that all connections have been made and that everything is present. nterconnecting wire routes can be displayed around, where particular containers or fixtures must be on the same circuit.
