An absence of voltage tester (AVT) includes a housing assembly, circuitry electrically connected to a power source, the circuitry configured to detect the absence of voltage, the circuitry configured to test for connectivity to the power source, means for a user to initiate a test for the absence of voltage, a supervisory test circuit within the circuitry to verify that the AVT is functioning properly, a set of visual indicators include a first visual indicator to confirm the absence of voltage after an absence of voltage test has been performed, a second visual indicator to display voltage presence between a first threshold and a second threshold, a set of visual indicators to display positive or negative voltage on each line of the power source when line voltage is present, and a secondary power source operatively connected to the supervisory test circuit for powering the supervisory test circuit.
An absence of voltage tester (AVT) for detecting absence of voltage comprising:
A method for performing testing of a power source with an absence of voltage tester (AVT), the method comprising:
