Applications:
1.Type THHN / THWN / THW / TW Cable is intended for general purpose applications as defined by the National Electrical Code (NEC)Type THHN-THWN-2 is permitted for new construction or rewiring for 60 volt applications. Applications requiring Type THHN or THWN.
a. THHN wire: It indicates a single or stranded conductor having flame-retardant and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 90°C dry only.THHN cable may also be used for wiring of machine tools, control circuits or on certain appliances.
b. THWN wire: It 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 cable is typically used for installation in conduit, machine tools, controlled circuits, or other general purpose wiring.
c.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.
d.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.
Building Wire Construction:
Insulation: PVC (Poly Vinyl Chloride) with Secondary Nylon Jacket
Conductor: Annealed solid or stranded copper wires (copper or CCA)
Voltage Rating: 600 Volts.
Standard:
Built to CSA C22.2 No.75
THHN or THWN-2* or MTW wire (also AWM) meets or exceeds all applicable ASTM specifications, UL Standard 83, UL Standard 1063 (MTW), Federal Specification A-A-59544, and requirements of the National Electrical Code.
