Building Wire
Features
QI® THHN/THWN-2 Marking
apply only to sizes 8 AWG up to
1000 kcmil.
Use of lubrication is not
mandatory to install QI® THHN/
THWN-2 conductors in the
raceways or cable trays.
PVC insulation offers exceptional
electrical, physical and flame-
retardant properties.
All sizes are also UL Listed as
MTW (Not Solid), AWM, GRII,
T90 Nylon, TWN75, and FT1.
All colors are rated For CT Use in
sizes 1/0 AWG and larger.
Sizes 8 AWG and larger rated SR
for Sunlight Exposure in all colors.
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.
All sizes meet VW-1 Vertical
Flame Test.
Colored insulation and Nylon
jacket is color coded (sizes
8 AWG and larger) for visual
identification of conductors in
electrical installations.
Application
CME Wire and Cable
QI® THHN/THWN-2 conductors
in all colors are suitable for use
in general purpose wiring in
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.

Engineering Information
1. Conductors: Soliduncoated
copper conductorsperASTM B3.
Stranded uncoatedcopper
conductors perASTMB3,B8
and B787.
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 QI® 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 QI® THHN/
THWN-2 conductors without the
use of a lubricant in an NFPA
70(NEC
®
) compliant installation.
