SCOPE

This specification describes single conductor THWN or THHN, a general purpose building wire insulated

with polyvinyl chloride (PVC) and covered with a tough protective sheath of nylon intended for lighting and power

circuits at 600 Volts or less, in residential, commercial and industrial buildings. The wire may be operated at 90°C

maximum continuous temperature in dry locations and 75°C in wet locations and is listed by Underwriters Laboratories
Fixed wiring,civil power,mobile equipment
