THHN – Indicates a single conductor having flame-retardant and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 90C dry only.
● THWN – Indicates a single conductor having flame retardant, moisture- and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 75°C wet or dry.
●THWN-2 – Same as THWN except that the wire is rated 90°C wet or dry.
●For THHN/THWN-2 applications, the conductor is appropriate for wet or dry locations not to exceed 90°C.
●C(UL): T-90 NYLON – Indicates a single-conductor, thermoplastic-insulated, nylon-jacketed construction having a rating of 90°C dry.
●C(UL): TWN75 – Indicates a single-conductor, thermoplastic-insulated, nylon-jacketed construction having a rating of 75°C wet or dry.
●CT Rated: 1/0 AWG & larger are rated for cable tray use.
●Gasoline and Oil Resistant II.
●Flame Retardant: VW-1 Rated.
●Sun Resistant
●RoHS Compliant
●Smooth nylon jacket aids in easier installation.
●Resistant to abrasion, moisture, heat, oil, gasoline, chemicals and grease
