Circuit Tracers


Locate cables behind walls, check for continuity, and identify circuit breakers. Connect the transmitter to an electrical receptacle or cable to send a signal to the receiver, which identifies the path of the cable or the correct breaker with a digital display, indicating lights, and sound alerts.
High-resolution circuit tracers have a receiver with adjustable sensitivity, so they can pinpoint the transmitter's signals from a greater distance than standard circuit tracers.

Circuit Breaker Identifiers


Identify the circuit breaker connected to an electrical receptacle. The transmitter plugs into the receptacle and sends a signal through the cable to the receiver. Move the receiver over the breakers, and light and sound alerts indicate when you find the correct breaker.
Circuit breaker identifer adapter kit traces breakers for light bulb sockets and switches.

Data Cable Identifiers

Trace unshielded data and telephone cables to their source. Attach the identifier with the included alligator clips and send a signal through the cable. The signal is then received by the removable handheld probe. As you get closer to the cable you're tracing, the probe's audio and visual signals get stronger.

Current Detectors

Check for the presence of AC current and voltage without making direct contact with a wire. The detector has light and sound alerts that indicate current when it is held near the electrical component.
