Power Trace


Allows a single operator to determine which breakers are feeding specific outlets in seconds.


"The other circuit tracer I have has been sitting under my desk since I received yours. Your testers are gold.  I am pretty impressed with them."

Inspector Line Load Simulator


Test branch circuits for load carrying ability and uncover faulty wiring without removing outlets, cover plates, or panel covers.

Efficiency and Reliability

Our electrical test tools are designed for ease of operation and reliable results. Our Buried Line Locator, for example, does not require manual signal strength adjustments. The Power Trace employs a uniquely synthesized signal that reduces the error rate to almost zero.

We are particularly proud of our advanced branch circuit testing equipment. The Circuit Mapper System has a revolutionary design that allows a single person to simultaneously trace circuits to multiple breakers; you no longer have to trace circuits one at a time. Its digital LED readout eliminates the need for signal strength comparisons.
