Applications:Type THHN/THWN-2 building wire is intended for general purpose applications as defined by the National Electrical Code (NEC). 6 AWG 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 AWM 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.Also Known As:Copper wire, THWN-2 Wire, building wire, hook up wire, conduit wire, hot tub wire, lighting wire, nylon copper wire, construction cable, 6 gauge wireFeaturesNylon outer jacket for easy pulling.
