Tracer wire is used for general purpose wiring circuits, machine tool wiring, and internal wiring of appliances. Common applications of TW/THW wire are for use in control panels, refrigeration equipment, air conditioning equipment, control wiring of machine tools, automatic washers and many more. This type of wire is also found in residential, commercial and industrial buildings. TW/THW is intended for use in dry areas not exceeding 90 degrees Celsius. The insulation on TW/THW wire is a heat and moisture resistant polyvinyl compound (PVC). This is available in 14-8 AWG.
Underground tracer wire is used to accurately locate underground pipes and lines. The underground tracer wire is laid alongside the pipes or lines during installation in order to find them at a later date for safe digging. Underground tracer wire is available in sizes 14- 8 6 AWG in an array of colors, depending on the intended use. The insulation on underground tracer wire is a high molecular weight, high-density polyethylene, which is resistant to abrasions,
crushing, chemicals, oils and moisture.
This specification describes a single conductor tracer wire. It is intended to carry a radio signal to aid in the location of buried plastic pipes. The wire may be identified by surface printing, indicating manufacturer and/or conductor size. Custom legends are available.
