In Figure 48–2, what is the purpose of normally closed contact F?

Expert Solution & Answer
Check Mark
To determine

Explain the scope of normally closed (NC) contact (F) in Figure 48-2.

Explanation of Solution

Refer to Figure 48-2 in the textbook shows that plugging the motor to stop from one direction only. In this figure, the normally closed (NC) contact F is mentioned as an interlock.

In Figure 48-2, while the stop button is pressed, the forward contactor will drop out and the coil (F) is a de-energized normally closed (NC) contact F. This contact in turn, energizes coil (R) to operate the motor in the reverse direction through the closed plugging switch.
