AC Circuit Indentifier uses wireless, non-contact abilities.

Press Release Summary:

Combining non-contact voltage and light detection with RF transmission technology, RT30 enables one user to identify mid-run wires or find breaker that powers circuit or light fixture remotely and without cutting into wire. Non-contact AC wiring identification, lighting circuit identification via built-in light sensor, non-contact handheld voltage (NCV) detection, and AC Outlet Extender capabilities are all standard.

Extech Instruments Announces RT30 Wireless Non-Contact AC Circuit Indentifier

Single-user remote non-contact Voltage or Light detection of branch circuits

Extech Instruments, a major supplier of test and measurement equipment for the industrial marketplace announces its new Model RT30. Ideal for residential electrical environments, the Model RT30 is a virtual electrician's helper, enabling a single user to identify mid-run wires or easily find the breaker that powers a circuit or light fixture without cutting into a wire, or relying on an assistant to remotely confirm the correct circuit breaker has been opened. The RT30 combines non-contact voltage and light detection with RF (Radio Frequency) transmission technology to simplify circuit identification and to eliminate back-and-forth trips to the circuit breaker panel.

Extech's RT30 features remote non-contact, mid-run AC wiring identification without cutting into wires, lighting circuit identification using a built-in light sensor, non-contact handheld voltage (NCV) detection, and an AC Outlet Extender that can be used to identify AC outlets. .

The RT30 was designed with a unique two-part system, consisting of a wireless transmitter and receiver. The wireless transmitter features a built-in, non-contact AC voltage detector that enables a single user to remotely identify a live mid-run cable, useful when adding new outlets or light fixtures for example. The unit clamps onto the cable and transmits a signal to the remote RT30 receiver indicating that voltage is present. Additionally, the built-in light sensor can identify lighting circuits and transmit a signal to the receiver indicating that the light is on or off reflecting the presence of voltage in that circuit. When the user opens the breaker switch, the voltage/light indicator and audible tone is turned off.

The RT30 identifies mid-run AC cables, circuit breakers connected to remote cables, lighting circuits, and AC power outlets. Using the clamp-on NCV probe, the RT30 identifies AC cables in hard-to-reach areas where the transmitters' built-in clamp cannot fit. The RT30 comes complete with transmitter, receiver, remote clamp probe, four AAA batteries and a case.
