The cable with Category A rated voltage is used in the situation requiring not over 1 min. of grounding fault lasting time. For the cable with
Category B rated voltage, the grounding fault lasting time normally is not over 1 hour, max. lasting time is not over 8 hours, annual ground fault
lasting time altogether should not be over 125 hours, Category C includes all the system expect Category A and B.
