Ive heard many a time that preforming AC Voltage withstand test can be damaging to Vacuum type circuit breakers. Is this true? If so to prevent damage can anyone inform me about where i can find information on testing procedures for this type of circuit breaker. The manual we recieved with our ABB VD4 breakers doesn't explain in much detail what procedures should be followed.
