Question 286Electricity & Electronics - Assistant Engineer

The correct answer is A) across-the-line starters. Induction motors of 5 horsepower or less are typically started using across-the-line starters. This is the simplest and most common method for starting these smaller motors. Across-the-line starters directly connect the motor to the full line voltage, providing the necessary starting torque without the need for additional equipment like resistors, autotransformers, or reactors. The other options, B) resistor starters, C) autotransformer starters, and D) reactor starters, are generally used for larger induction motors that require more controlled starting methods to limit the initial high starting current and avoid voltage dips on the power system.
