With what kind of starting equipment are most three-phase induction motors of five horsepower or less started?

Correct Answer: Option D — across-the-line starters

Across-the-line starters are standard for small induction motors, typically five horsepower or less. Because these motors have low starting current surges, they can be connected directly to the line voltage without causing excessive voltage drops or mechanical stress, complying with standard marine electrical distribution practices outlined in IEEE 45.
