Every household needs this indispensable tool set when tackling an electrical project. GB's Circuit Alert non-contact voltage tester audibly (beeping) and visually (flashing) indicates AC voltage from 50V to 600V. Use to locate breaks in wires and "hot" voltage at receptacles, switches and motors. Fully insulated probe tip eliminates the risk of contacting live wires. 1 - AAA battery required (incl); built-in safe test feature indicates tester and batteries are working properly. Also included in the kit is a 6-in-1 function hand-tool! In addition to cutting wire of almost any gauge this tool also strips 10-22 AWG copper or aluminum wire, solid or stranded, crimps insulated and non-insulated 10-22 AWG terminals and coaxial connectors, cuts and rethreads mild steel untempered bolts in common thread sizes, includes a plier nose for gripping wire and tightening or loosening small nuts, and built in looping holes make it easy to loop solid wire quickly.
