C. 3.5 seconds

The inrush current of a motor on a disconnect system can exceed the rated current value of the Overcurrent device for a short duration during motor startup. This duration depends on various factors such as motor type, size, and the characteristics of the connected load. It is important to consider the time required for the motor to reach its optimum RPM (Revolutions Per Minute) and stabilize.
