THHN/THWN/TW/THW Cable
Type THHN/TTHWNTHWN-2 building wire is intended for general purpose applications as defined by the National Electrical Code (NEC). Type THHN/THWN/THWN-2 is permitted for new construction or rewiring for 600-volt applications. For 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. For applications requiring Type MTW, the 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

TW/THW/THW-2 Cable
THW wire– Indicates a single conductor having flame-retardant, moisture and heat-resistant thermoplastic insulation. The wire is rated 75°C wet or dry.THW cable and wires are used generally in building wiring, feeder and branch circuits, and internal secondary industrial distribution.
TW wire– Indicates a single conductor having flame-retardant, moisture-resistant thermoplastic insulation. The wire is rated 60°C wet or dry.TW cable and wires are used generally in building wiring, feeder and branch circuits, and internal secondary industrial distribution
