Abstract
A hand tool and an accessory which provide an alarm signal to a user as the tool or accessory approaches a live electrical wire are disclosed. The hand tool or accessory include a non-contact voltage sensing circuit. As the tool or accessory approaches a live electrical wire, the non-contact voltage sensing circuit detects the voltage, triggering an alarm circuit. The alarm circuit provides a visual or audio signal to the user. The hand tool can be selectively coupled to the tool head.
