About this item
The Amprobe AT-4000 Series is an advanced wire tracer built for electricians and facility technicians who need to follow wiring hidden in walls, floors, and conduit. It traces both energized and de-energized circuits without interrupting power, pinpointing breakers, shorts, open or broken wires, neutrals, and ground lines. The T-4000-A universal transmitter operates from 9–300 V AC/DC and switches automatically between live and dead circuits, while the R-4000 receiver displays signal strength to home in on the conductor, with up to 20 ft of in-air range in short mode and 12 ft in open mode.
This listing is the AT-4000-A Advanced Circuit Tracer Kit, new and complete with case and accessories. As photographed, the kit includes the T-4000-A transmitter, R-4000 receiver, a clamp-on accessory for injecting the tracing signal without touching bare wire, pigtail and alligator leads, a grounding lead and clip, batteries, manuals, and the soft carry case.
Condition: New, sealed, as listed. The photographs are of the actual unit you'll receive, covered by our warranty.
