Line Fittings Detection Of The Highest Reverse Breakdown Voltage

Insulation Piercing Connector detects the highest reverse breakdown voltage:

For AC, because it is constantly changing, the highest reverse working voltage is the AC peak voltage that the diode withstands. It should be pointed out that the highest reverse working voltage is not the breakdown voltage of the diode. Generally speaking, the breakdown voltage of the diode is twice as high as the highest reverse working voltage.
