With the AT-6010-EUR advanced wire tracer kit, it’s never been easier and safer to locate energized and de-energized wires, breakers and fuses. When the transmitter is connected to the circuit, the receiver easily detects the signal in the wires or cables behind walls, ceilings and floors. The transmitter works on energized and de-energized circuits, allowing for work directly on an energized circuit without the need to take equipment offline.
