Textbook Question
Chapter 5, Problem 15RQ
Refer to the circuit shown in Figure 5-29. In this circuit, the HR contactor is equipped with five contacts. Three are load contacts and two are auxiliary contacts. From looking at the schematic diagram, how is it possible to identify which contacts are the load contacts and which are the auxiliary contacts?
Figure 5-29 The contactor contains both load and auxiliary contacts.
