The Amprobe AT-6020 wire tracer kit combines a Receiver and powerful Transmitter to locate energized and de-energized wires, breakers, and fuses without having to disconnect any equipment. The Receiver features four tracing modes optimized for a range of applications. Its fully automatic breaker tracing capability saves time and eliminates the confusion of multiple false positives by detecting the highest recorded signal in a breaker or fuse. The Transmitter utilizes two optimized frequencies that allows for a clean and reliable signal. The (Optional) Signal Clamp can be used in applications where there is no access to bare conductors by enabling the Transmitter to induce a signal into a wire through insulation. Whether you're a novice user or an expert, the AT-6020 Amprobe Advanced Wire Tracer kit will help you get the job done fast.
