18 Stranded TFFN Copper - Grey - 500 ft.

Type TFFN stranded copper conductors are primarily used as fixture wire as specified by the National Electrical Code (NEC 2008 Edition) at temperatures not to exceed 90 degrees C in dry locations. When used as type MTW, conductor is suitable for use in dry locations at 90 degree C, or not to exceed 60 degrees C in wet locations or where exposed to oils or coolants. When used as type AWM temperatures should not exceed 105 degrees C in dry locations. Voltage rating for all applications is 600 volts. TFFN or MTW or AWM copper conductors are annealed (soft) copper, insulated with a tough, heat and moisture resistant polyvinyl chloride (PVC), over which a nylon (polyamide) jacket is applied.
