What a Non-Contact Voltage Tester Can Tell You
A non-contact voltage tester can quickly indicate that alternating-current voltage may be present near a wire, cord, outlet, or fixture without exposing a conductor. That makes it useful for preliminary checks and for locating an energized cable among several similar ones.
