PCE Instruments - Model PCE-191 CB - Cable Detector

The cable detector is used for detecting cables and power lines in walls. This cable detector is both a transmitter and receiver. The transmitter of the cable detector has a connector that can be connected to a power connector (max. 240 VAC) and emits acoustic signal for live cables. It can follow the signal of a cable with the receiver from the wall to the fuse. If the cable detector finds an interruption in a cable, the signal goes off. It's also possible to easily locate the fuse for a cable when it's not clearly marked in a fuse box. Connect the transmitter of the cable detector to the corresponding circuit connector and use the receiver to find the correct fuse. The line can be kept live while all of these functions are performed. At this link you will find other types of a high quality cable detector.
