Developing a Wiring Digram (Circuit #3)

Objecfjves

After studying this unit, the student will be able to:

• Develop a wiring diagram using this schematic

• Connect this circuit

Figure 35-1 shows the same schematic as fig­ Jre 32-1, except that figure 35-1 has been labeled with numbers in the same manner as the two pre­ vious circuits. Figure 35-2 shows the components of the wiring diagram labeled with numbers that correspond to the numbered components shown in the schematic. Figure 35-3 shows the wiring dia­ gram with connected wires.

The same method has been used to number the circuits in the last few units. Although most control schematics are numbered to aid the elec­ trician in troubleshooting, several methods are used. Regardless of the method used, all number ­ ing systems use the same principles. An electrician who learns this method of numbering a schematic will have little difficulty understanding a different

method.

REVIEW QUESTION

1. Are numbering systems other than the one described in this text used to develop wiring diagrams from schematic diagrams?
