This category covers thermoplastic-insulated wire. It is rated 600 V, and certified in sizes 0.5 through 1000 sq mm copper, copper clad-aluminum, or aluminum. The cable complies with all the requirements specified in UL 83, "Thermoplastic-insulated Wires and Cables," except that metric conductor sizes are used instead of AWG/kcmil sizes. This cable is for use in jurisdictions where metric conductor sizes are required or permitted. Thermoplastic-insulated wire is designated as follows: TW — Indicates a single conductor having flame-retardant, moisture-resistant thermoplastic insulation. The wire is rated 60°C wet or dry. THHN — Indicates a single conductor having flame-retardant and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 90°C dry. THW — Indicates a single conductor having flame-retardant, moisture- and heat-resistant thermoplastic insulation. The wire is rated 75°C wet or dry. THW-2 — Same as THW except that the wire is rated 90°C wet or dry. THHW — Indicates a single conductor having flame-retardant, moisture- and heat-resistant thermoplastic insulation. The wire is rated 90°C dry and 75°C wet. THWN — Indicates a single conductor having flame-retardant, moisture- and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 75°C wet or dry. THWN wire suitable for exposure to mineral oil and to liquid gasoline and gasoline vapors at ordinary ambient temperature is marked "GR I" if suitable for exposure to mineral oil at 60°C, or "GR II" if the compound is suitable for exposure to mineral oil at 75°C. Gasoline-resistant wire has been tested at 23°C when immersed in gasoline. It is considered inherently resistant to gasoline vapors within the limits of the temperature rating. THWN-2 — Same as THWN except that the wire is rated 90°C wet or dry.PRODUCT MARKINGS Types TW, THW, THW-2, THHN, THHW, THWN, and THWN-2 conductors that are marked "CT" comply with a vertical-tray cable flame test. Wire so marked may additionally be marked "SR" indicating compliance with an artificial weathering test. Types TW, THW, THW-2, THHW, THWN and THWN-2 in all sizes that are marked "SR" comply with an artificial weathering test. Wire suitable for exposure to mineral oil is marked "PR I" or "PR II," on the surface of the wire. An oil resistant marking, by itself, does not include resistance to gasoline or similar light petroleum solvents. Wire that complies with a special vertical flame test is surface marked "VW-1." Constructions in this category that comply with a flame and smoke test (as described in UL 1685, "Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables") may have the additional marking "ST1" indicating "Limited Smoke." In place of three of the markings described above, the following multinational markings may be used: "Sunlight Resistant" in place of "SR" "Oil Resistant" in place of "PR" "Gasoline and Oil Resistant" in place of "GR" Submersible Pump Cable — Indicates multiconductor cable consisting of two or three flat or two to six twisted insulated conductors with or without an overall jacket. The cable is labeled in size 2.5 sqmm to 240 sq mm copper, and 4 sq mm to 240 sq mm aluminum or copper-clad aluminum. The cable is tag marked "For Wiring Only Between Equipment Located at Water Well Heads and Motors of Installed Deep-Well Submersible Water Pumps." The insulation is surface marked "Submersible Pump Cable." The cable has not been investigated for direct burial in the earth. Wire, in sizes mentioned below, may employ copper or aluminum, or copper-clad aluminum conductors. Wire with copper-clad aluminum conductors is surface printed "AL (CU-CLAD)" or "Cu-Clad Al."Wire with aluminum conductors is surface printed "AL." Wire and cable employing compact-stranded copper conductors is so identified directly following the conductor size, wherever it appears (surface, tag, carton or reel), by "compact copper."The abbreviations "CMPCT" and "CU" may be used for compact and copper, respectively. Tags, reels and cartons for product employing compact-stranded copper conductors have the marking: "Terminate with connectors identified for use with compact-stranded copper conductors."
