131. In which of the following branch circuits types would time lag fuses (or dual-element fuses) be MOST likely used?

Time-lag fuses are primarily used in motor starting circuits to accommodate the high inrush current during motor startup, which would otherwise trip standard fuses. These fuses are designed to tolerate brief, high currents while still providing protection against sustained overloads or short circuits, a characteristic unnecessary for general alarm, emergency lighting, or main lighting circuits.
