Abstract: A voltage sense lead and continuity termination (VSLT) assembly module for use with a source conductor of a power source includes a first voltage sense lead and continuity termination (VSLT) circuit, and a second voltage sense lead and continuity termination (VSLT) circuit, wherein the first VSLT circuit is electrically connected to the source conductor for a phase of the power source at a first voltage termination lead (VTL) connection point, wherein the second VSLT circuit is electrically connected to the source conductor for the phase of the power source at a second voltage termination lead (VTL) connection point, and wherein the first VTL connection point and the second VTL connection point are positioned at the source conductor such that a conductive bridge of the source conductor extends between the first VTL connection point and the second VTL connection point. The VSLT may be used in an Absence of Voltage Tester (AVT) or a power supply conversion circuit or otherwise.

Abstract: The device may include a housing assembly. Also, the device may include analog circuitry electrically connected to a power source. Furthermore, the device may include the analog circuitry configured to detect the presence of voltage. In addition, the device may include the analog circuitry configured to test connectivity to the power source. Moreover, the device may include means for a user to initiate a test for the absence of voltage. Also, the device may include a supervisory test circuit within the analog circuitry to verify that the AVT is functioning properly. Furthermore, the device may include a visual indicator within the analog circuitry to confirm the absence of voltage after an absence of voltage test has been performed. In addition, the device may include a secondary power source operatively connected to the supervisory test circuit for powering the supervisory test circuit.
