Greenlee 52084825 SEEKER, CIRCUIT (CS-5000)

The Greenlee CS-5000 is a transmitter/receiver circuit tracing kit. It traces cables, identifies which breaker or fuse feeds a given circuit, troubleshoots circuits, and locates faults in conduit. Typical use is clipping the transmitter onto the circuit at a receptacle or device, then sweeping the receiver across the panel until the LED array peaks on the right breaker.

The transmitter and receiver can be separated by up to 4 miles, so one tech can hook onto a circuit in a far unit while another works the panel in another building. That is separation distance, not sensing distance: the receiver picks up the signal on the conductor at a range of up to 20 feet.

The receiver on the CS-5000 has a range of up to 20 feet, so it will pick up a signal through drywall, ceiling cavities, and normal building finishes at that distance from the conductor. Depth through slab or fill still comes down to how far the wire sits from the receiver, so anything beyond that 20 foot window will not read.

Four AA cells total across the kit. Keep a spare set in the bag, since weak batteries on the transmitter show up as a short, mushy reading at the receiver rather than as a dead unit.

Readout is an LED linear array rather than a numeric screen. You sweep the breakers and watch for the bar to climb, then back off and repeat over the candidates until one peaks clearly above the rest. That style of display is easy to read in a dim electrical room and does not need you to interpret a number.

The CS-5000 measures 13.4 inches by 10.8 inches by 5.2 inches, with a packaged weight of 3.845 pounds. That is a carry case footprint, not a pouch item, so plan a shelf or drawer rather than a belt pouch.

Order it as Greenlee 52084825, the CS-5000 circuit seeker. Country of origin is the US, which matters if you are buying under a domestic preference or a government MRO spec.
