Tray-rated cables came about when failures on power and communications cables were becoming quite common. Our pulley cord is constructed using three copper wires, each stranded and covered in PVC insulation. The most commonly used interior wiring in USA is a 12 or 14-gauge NM (nonmetallic) sheathed cable, sometimes called "Romex. "Although nonmetallic-sheathed cable, or NM for short, was first listed and described in the NEC in 1926, it was actually invented a few years earlier by General Cable at their Rome Wire Division in Rome, NY, and marketed under the trade name “Romex®. Some people will refer to this wire as the "case ground" since this wire is typically connected to the cases or outer parts of electrical boxes and appliances and tools. General Requirements 300.
