What occurs when the power resumes after an interruption to a motor if the starter is a manual toggle switch type?

• A. The motor will remain off
• B. The motor will try to restart, and fuses or circuit breakers may blow
• C. The motor will switch to a low power mode
• D. The motor will require manual resetting

Answer: (B)

When the power resumes after an interruption and the motor is controlled by a manual toggle switch type starter, the motor will try to restart automatically because the manual toggle switch does not have a locking mechanism to prevent it from re-engaging when power returns. This can result in the motor attempting to start without any checks in place to manage the restart safely. If the motor encounters resistance, such as a mechanical jam or overload, it may draw excessive current, leading to blown fuses or tripped circuit breakers designed to protect the circuit from overload conditions. This situation emphasizes the importance of using starters with built-in safety features that prevent motors from restarting unexpectedly after a power interruption.
