Extech RT30 Wireless AC Circuit Identifier
Virtual electrician’s helper remotely identifies and confirms correct circuit is opened. Combines non-contact voltage and light detection with RF (Radio Frequency) transmission technology. It enables a single user to identify mid-run wires and to find the breaker that powers a circuit or light fixture without having to connect directly to the wires in the cable.
Three Easy Steps:
1. Clamp the transmitter directly onto installed wiring to detect voltage.
2. The receiver alerts the user at the breaker panel with a voltage-present LED indicator and audible beep.
3. Alerts cease when the right circuit breaker is switched off or a junction splice is opened in the circuit.
• Simplify mid-run wiring jobs by easily identifying the correct
circuit powering the cable to be spliced or repaired
• The innovative RT30 combines non-contact voltage detection
with wireless signals to monitor and remotely report the
presence of voltage on a wire
• Clamped onto a live wire, the transmitter signals the user at
the breaker panel with LED and audible alerts on the receiver
(up to 100m range). The alerts stop when the correct circuit
breaker is switched and work can then be performed safely.
• Eliminates the need for an assistant or back-and-forth trips to
confirm the correct circuit is powered down
• The RT30’s clamp-style probe accessory is ideal for
wires that are hard to isolate or reach
• Plus, easily identify lighting and outlet circuits
with the built-in light sensor
