Which statement about reduced voltage starters is true?

• A. They reduce starting current inrush
• B. They increase starting torque
• C. They have no effect on inrush
• D. They are faster to install

Answer: (A)

Reduced voltage starters apply a lower voltage to the motor during startup, which directly limits the current the motor draws at the moment it starts. That lowered current is the inrush current, so this approach effectively softens the electrical surge and reduces stress on the power supply and wiring. Because the starting torque is tied to the voltage applied (torque falls as voltage is reduced), these starters do not increase starting torque; they actually reduce it. They also aren’t inherently faster to install, since adding a reduced-voltage setup often involves additional components and wiring beyond a simple direct start.
