Due to the operating characteristics of the system, time lag fuses (or dual-element fuses) are necessary for use in what types of circuits?

Correct Answer: Option C — motor starting circuit

Motor starting circuits experience high inrush currents that can exceed nominal ratings for several seconds. Time-lag or dual-element fuses are required to prevent nuisance tripping during these transient surges while still providing protection against sustained overloads or short circuits that could damage the motor windings or supply cables.
