Capacitor-start capacitor-run motors that are not hermetically sealed contain a centrifugal switch to disconnect the start capacitor when the motor reaches about ____% of its full load speed.
A) 25
B) 50
C) 75
D) 90

Question

Quizplus · Accepted Answer

Capacitor-start capacitor-run motors use a start capacitor for additional torque during startup, but once the motor reaches about 75% of its full load speed, the capacitor is no longer needed and can actually hinder the motor's performance. To avoid this, a centrifugal switch is used to disconnect the start capacitor at this point. Therefore, choice C (75%) is the correct answer.

Capacitor-Start Capacitor-Run Motors That Are Not Hermetically Sealed Contain a Centrifugal
