SPECIFICATION:


1. SCOPE
1.1 This specification describes single conductor THW, a general purpose building wire insulated with polyvinyl chloride (PVC) intended for lighting and power circuits at 600 volts or less, in residential, commercial and industrial buildings. The wire may be operated at 75° C maximum continuous conductor temperature in wet or dry locations and is listed by Underwriters Laboratories for use in accordance with Article 310 of the National Electrical Code.

2. APPLICABLE SPECIFICATIONS
2.1 The following specifications form a part of this specification to the extent specified herein:
2.1.1 Underwriters Laboratories Standard 83 for Thermoplastic Insulated Wires.
2.1. 2 Federal Specification J-C-30B.

3. CONDUCTORS
3.1 Conductors shall be solid or Class B stranded, annealed uncoated copper per UL Standard 83.

4. INSULATION
4.1 Each conductor shall be insulated with PVC complying with the physical and electrical requirements of UL Standard 83 for Type THW. In addition, the PVC insulation shall comply with the optional Oil Resistant I listing of UL Standard 83.
4.2 The average thickness of insulation, for a given conductor size, shall be as specified in UL Standard 83 for Type THW wire. The minimum thickness at any point shall be not less than 90% of the specified average thickness.
The insulation shall be applied tightly to the conductor and shall be free-stripping.

5. IDENTIFICATION
5.1 The wire shall be identified by surface marking indicating manufacturer's identification, conductor size and metal, voltage rating, UL Symbol, type designation and optional ratings.


6. TESTS
