Begin by examining all visible electrical devices—switches, outlets, and light fixtures—on the affected circuit, as hidden boxes are often placed near. Somewhere in that wall, there's a junction box you can't see— The Ghost Junction —tying those three circuits together. The problem is buried behind drywall, and you're facing what electricians call The $2,000 Wall Decision: guess wrong about where that. The best method to trace wiring is by using a wire tracer, which enables you to locate wires hidden within walls without damaging your property. This tool simplifies the process and ensures that you can confidently complete any electrical task. Mark each wire and take notes or photos of their routing. A wire tracer tool is an electronic testing device used to locate, identify, and trace electrical wires, cables, breakers, and hidden connections inside walls, ceilings, floors, conduit systems, and underground installations.
