Abstract

An apparatus for deterring removal of electrical wiring that is installed in a building includes a controller, and a wiring module responsive to the controller and forming a monitored circuit with installed electrical wiring by coupling to an end of the wiring located at a load distribution junction. The other end of the wiring is electrically coupled, and can be coupled with a controlled impedance, or with a protected asset. The apparatus is configured with control logic to issue an alert if the integrity of the monitored circuit has been compromised.
