We’ll discuss the elements of a wiring diagram, provide an example of a diagram for a C15 generator, and offer advice on interpreting and using the diagram effectively.

Elements of a Generator Wiring Diagram



A generator wiring diagram is a diagram that outlines the electrical connections and power components required for an individual generator. All diagrams use essential symbols and icons to explain the components of the generator in an easy-to-understand way.

Some of the most common symbols and icons used in generator wiring diagrams include:


  • Circuitry/Schematic Components: These symbols represent all the electrical and mechanical components that make up the generator. Examples include switches, breakers, circuit breakers, fuses, transformers, relays, and resistors.


  • Power Sources: These symbols represent the connections between the circuit components and the power sources. Examples include AC and DC power sources, battery sources, and solar power sources.


  • Wiring: These symbols denote the wires and connectors between the circuit components and the power sources. Examples include jumper wires, insulated wires, and shielded cables.
