DIFFERENCE BETWEEN SCHEMATIC AND WIRING DIAGRAM

30/11/2021

What is the difference between schematic and wiring diagrams?

In a schematic diagram, lines are used to represent wires, and symbols are used to represent components.

Example of schematic diagram

 

The schematic diagram does not show the practical connection between the components or their position. It contains only symbols and lines.

A wiring diagram is a generalized pictorial representation of an electrical circuit. The components are represented using simplified shapes in wiring diagrams. Wiring diagrams generally give detailed information about the relative location and arrangement of devices.
