Voltage Detectors
Confirm that voltage is present in receptacles, cables, and other electrical components. The detectors have light or sound alerts to indicate voltage.
Long-reach tips, tests leads with sheathed alligator clips, and test leads with needle tips must touch the electrical component you're testing to sense voltage.
