Product Description

THHN/THWN-2 Copper, PVC Insulated

Nylon Jacket, 600 V

A

Features

THHN/THWN-2 Marking apply only to sizes 8 AWG up to 1000 kcmil.

Use of lubrication is not

mandatory to install THHN/ THWN-2 conductors in the

raceways or cable trays.

PVC insulation offers exceptional electrical, physical and flame-

retardant properties.

All sizes are UL/cUL Listed as MTW (Not Solid), AWM,

T90 Nylon, and TWN75.

All sizes meet VW-1 and FT1 Vertical Flame Test.

All colors in sizes 1/0 and larger are UL listed and marked CT USE in accordance with NEC meeting UL 1685 vertical-tray flame test and also marked FT4 meeting

IEEE 1202 vertical-tray test both at 70,000 BTU/Hr.

All colors in sizes 8 AWG and larger are rated SR for Sunlight Resistance exposure.

All sizes and colors are GRII for Gasoline and Oil resistance.

RoHS compliance in sizes 14 AWG to 10 AWG.

BIG Sequential Footage Marking for easy identification, in sizes 1/0 AWG and larger, every 1 ft.

Colored insulation and a nylon jacket are color-coded (sizes 8 AWG and larger) for visual identification of conductors in electrical installations.

Engineering Information

1. Conductors: Solid uncoated

copper conductors per ASTM B3.

Stranded uncoated copper conductors per ASTM B3, B8 and B787.

On request, Class I for conductor size 250 kcmil to 1000 kcmil per per ASTM B172 and ASTM B174.

2. Insulation: Polyvinyl Chloride (PVC) per UL 83 and UL 1063.

3. Jacket (color coded): Low

friction tough polyamide, Nylon, per UL 83 and UL 1063.

Installation Performance A significant reduction (25% – 30%) in the pulling force is achieved

for THHN/THWN-2 when

compared to the pulling forced required for Standard THHN/

THWN-2 without any lubricant. Further, this reduction is

• comparable to the reduction
• achieved when the Standard
• THHN/THWN-2 conductors
• are pulled using a lubricant in
• identical installation. These
• results demonstrate that it is

feasible to install the THHN/ THWN-2 conductors without the use of a lubricant in an NFPA

70 (NEC ) compliant installation.

Application

HNQZ Wire and Cable

THHN/THWN-2 conductors in all colors are suitable for use in general-purpose wiring in

Bu i ld ing Wire

accordance with the

requirements of NFPA 70 (NEC ). Type THHN/THWN-2 conductors are approved for use at a

maximum voltage of 600 volts and a maximum conductor

temperature of 90 °C in wet or dry locations and 75 °C when exposed to gasoline and oil.

Also rated AWM for 105 °C dry and 80 °C in oil.
