A voltage detector is a tool that senses electrical current. Voltage detectors can sense electrical current through a cable's sheathing, wire's insulation and electrical boxes. Just place the tip of the voltage detector on the wire or box and the voltage detector will either light up or beep (depending on the model) if there is current.
