DOE-HDBK-1016/1-93ELECTRICAL DIAGRAMS AND SCHEMATICSElectrical Diagrams and SchematicsFigure 10 provides an example of the relationship between a schematic diagram (Figure 10A) anda wiring diagram (Figure 10B) for an air drying unit. A more complex example, the electricalcircuit of an automobile, is shown in wiring diagram format in Figure 11 and in schematic formatin Figure 12. Notice that the wiring diagram (Figure 11), uses both pictorial representations andschematic symbols. The schematic (Figure 12) drops all pictorial representations and depicts theelectrical system only in symbols.Figure 10 Comparison of an Electrical Schematic and a Wiring DiagramPR-03Rev. 0Page 10
