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.
