Which statement correctly describes a full voltage starter?

• A. Uses resistors in the starting circuit
• B. One contactor
• C. Two contactors and a time delay relay
• D. Two contactors

Answer: (B)

A full-voltage starter applies the motor’s full line voltage to the windings as soon as starting is initiated, without reducing it first. The simplest way to do this is with a single contactor that connects the motor to the supply, usually with an overload protection device in series for protection. That’s why using one contactor best describes a full-voltage starter—there’s no resistors or timing network to drop or control the voltage during start. The other options describe reduced-voltage methods or different interlock schemes: introducing resistors in the starting circuit reduces the voltage seen by the motor; a setup with two contactors plus a time-delay relay is typical of a star-delta or similar reduced-voltage start; two contactors alone could be part of another scheme but doesn’t define full-voltage starting by itself.
