What type of diagram shows how an individual device or component is wired?

A wiring diagram serves as a visual representation of how an individual device or component is wired. It provides a detailed view of the internal structure and interconnections of the electrical components, showing how wires connect to terminals and devices. This type of diagram is most useful for troubleshooting and repairs since it conveys the precise layout and relationships of the components, making it easier to understand how power flows through the system.

In contrast, a one line diagram simplifies the representation of an electrical system by depicting only the essential components with single lines, making it less detailed for individual devices. A ladder diagram is typically used to illustrate control circuits in relay logic and is structured more like a ladder, showing the relationship between power and control elements rather than wiring specifics. An operational diagram focuses more on the functionality and operation of the system rather than the wiring connections. Each of these other diagram types serves distinct purposes, emphasizing different aspects of electrical engineering and circuitry.
