Scope: This specification describes single conductor polyvinylchloride (PVC) insulated, 600-volt dual rated type TW/THW. It is intended for ground wire and other general purpose power wiring. It is suitable for lighting and power in residential, commercial and industrial applications with circuits at temperatures from -25C to 75C in wet or dry locations per NEC Article 310 and NFPA Standard 70. This product complies with EU Directive 2002/95/EC known as ROHS.

Applicable Standards:

· ASTM B-1, B-3, and B-8 for copper conductors.

· Underwriters Laboratories (UL / CUL) Standards as follows: 83 (TW/THW) for Thermoplastic Insulated Wire.

Conductors: The single copper conductors shall be solid or stranded annealed or hard uncoated copper per UL83 and ASTM requirements.

 Insulation: The conductor shall be insulated with PVC as specified and applied tightly to the conductor in a concentric manner. The minimum at any point shall not be less than 90% of the specified average thickness in compliance with UL 83.

 Identification: The wire shall be identified by surface or indent marking indicating the manufacturer, conductor size, voltage rating, UL symbol, and type designation.

Packaging: Standard packages are 500 ft/spool. – 4 per carton, 500 ft. knockout cartons, or 2500 feet/spool. Custom lengths are available.

Testing: The wire shall be continuously spark tested at 7500 Volts DC. Other electrical and mechanical tests shall be in accordance with UL 1581. AWG
