When performing an absence-of-voltage test, a live-dead-live test may be required in conjunction with the absence-of-voltage test. What is the purpose of the live-dead-live test?
Official USCG Answer & Rule Citation
Correct Answer: Option A — The live-dead-live test proves the functional ability of the voltage tester to measure voltage prior to and after conducting the absence-of-voltage test which validates the results of the absence-of-voltage test.
The live-dead-live verification process ensures testing equipment is fully operational immediately before and after an absence-of-voltage test, eliminating false negatives caused by internal meter failures and validating the zero-energy state of marine circuits.
