ABSTRACT:
A test device for testing for the presence of voltage on an electrical power cable has a manually graspable handle and a probe mounted on the handle for projecting forwardly for engaging the power cable. The housing contains an electronic detection circuit responsive to signals from the probe for detecting presence of voltage on the cable and an indicator light for providing a warning indication in response to the detection of a voltage. The probe has a v-shaped mouth for surrounding the cable and a central rod for engaging into the cable. The mouth is retracted by pressure to expose the rod. The rod engages between the exposed neutral wires of one type of cable or into a punched hole in a cable of the type having a jacket.
