FeaturesMade in U.S.A.2 Year Warranty Determines which breakers are feeding specific outlets in seconds.Traces 9-600 volt wiring in floors, ceilings and walls from the power source to the receptacle.Ignores noise and interference from outside sources with its exclusive dual filter system.Eliminates equipment downtime because circuits are tested with power on.Affordable enough to have a unit in every tool box.Saves hours of time and only requires one operator.Download ManualThe Power Trace System Traditional methods of locating breakers and wiring are inefficient and expensive, often requiring two operators and a radio. In addition, the breakers have to be flipped on and off. Due to computers and voltage sensitive equipment this task is often performed during off hours or specific days with scheduled computer downtime. Using the POWER TRACE ™ will greatly reduce man hours involved in locating breakers, fuses, and wires!How It Works The POWER TRACE ™ TRANSMITTER draws current from a 9-600 volt line in a very unique manner. The current drawn is a microprocessor controlled precision combination of separate frequencies that create a composite signal. This composite signal gives a very specialized "signature" to the signal. To be received, the signal must have this exact combination of frequencies. This feature greatly reduces the possibility of interference from electrical noise. This "signature" is present everywhere along the current path, including through breaker, fuses, and transformers. An LED on the TRANSMITTER shows that the circuit has power and the unit is functioning properly. The POWER TRACE ™ RECEIVER is tuned to pick up only the magnetic "signature" caused by the TRANSMITTER. The signal is indicated by both fixed signal strength and variable signal strength LEDs.Additional Features The POWER TRACE ™ can follow wires up to a 20 foot depth. Not only is it affordable, it is tough enough to last for years in your tool box. The POWER TRACE ™ is a light weight and compact unit. Set includes all available accessories, battery and a durable carrying case.
