APPLICATIONS:
THHN/THWN-2 building wire is intended for general purpose applications as defined by the National Electrical Code (NEC). THHN-THWN-2 is permitted for new construction or rewiring for 600-volt applications. Applications requiring Type THHN or THWN-2, the conductor is appropriate for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C in oil or coolants. Applications requiring Type MTW conductor is appropriate for use in dry locations at 90°C, or not to exceed 60°C in wet locations or where exposed to oils or coolants. Applications requiring Type AWM conductor is appropriate for use at temperatures to not exceed 105°C in dry locations. Most common building wire used often on sub-panels, hot tubs & jacuzzis.
FEATURES:
THHN copper conductors are designed to be installed without application of a pulling lubricant. All sizes are rated gasoline and oil-resistant.
MATERIALS:
Jacket is heat and moisture resistant, colored polyvinyl chloride (PVC) insulation, with a clear nylon (polyamide) or UL-listed equal jacket, which provides abrasion resistance.
Conductors are stranded soft drawn copper, per ASTM standards
