How can you identify a capacitor-start motor visually?

• A. By the presence of a starter relay attached
• B. By the presence of a fuse connected to the wiring
• C. By the presence of an external capacitor connected to the motor windings
• D. By the size of its housing

Answer: (C)

A capacitor-start motor can be identified visually by the presence of an external capacitor connected to the motor windings. This capacitor is crucial for the motor’s starting mechanism, as it provides the necessary phase shift that helps generate a starting torque when the motor is first energized. The capacitor is typically housed in a plastic or metal casing and is not integrated into the windings of the motor itself, making it easily identifiable. The other options may relate to different aspects of motor design or functionality but do not specifically point to a capacitor-start motor. For instance, a starter relay is found in various types of motors and isn't exclusive to capacitor-start types. Similarly, fuses serve general protective purposes across many electrical systems and aren’t indicative of any specific motor type. Lastly, the size of the housing varies among motors based on design and application and does not directly correlate with the need for a capacitor in the starting procedure. Thus, the presence of an external capacitor is the definitive characteristic that identifies a capacitor-start motor visually.
