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

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

Induction motors rated at five horsepower or less are typically rugged enough to withstand the initial inrush current of across-the-line starting. This direct-on-line method provides maximum starting torque without requiring complex reduced-voltage starters, compliant with IEEE 45 recommendations.
