Construction:

Conductor: Sizes #8 AWG - 3/0 AWG use a Class B stranded combination-unilay soft drawn annealed bare copper per ASTM B787. Sizes 4/0 AWG and larger use a Class B stranded compressed annealed bare copper per ASTM B8
Insulation:Heat and moisture resistant PVC
Sheath:Nylon jacket utilizing SIMpull^® Technology

Applications and Features:

Southwire SIMpull^® THHN/THWN-2 copper conductors are primarily used in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications as specified in the National Electrical Code® and other applicable codes and standards. Voltage for all applications is 600 volts. SIMpull^® THHN/THWN-2 copper conductors are designed to be installed without the application of a pulling lubricant. These conductors have multiple ratings depending upon the product application. Allowable temperatures are as follows:
- THHN or T90 Nylon- Dry locations not to exceed 90°C
- THWN-2- Wet or dry locations not to exceed 90° C or locations not to exceed 75°C when exposed to oil
- TWN75- Wet locations not to exceed 75°C
- MTW- Wet locations or when exposed to oil at temperatures not to exceed 60°C or dry locations not to exceed 90°C (with ampacity limited to that for 75°C conductor temperature per NFPA 79)
- AWM- Dry locations not to exceed 105°C only when rated and used as appliance wiring material

FEATURES
- Sunlight resistant #8 AWG and larger
- Gasoline and Oil Resistant II
- CT Rated 1/0 AWG and Larger
- VW-1 All Sizes
- FT-1 All Sizes
- AWM- Sizes 14 through 6 AWG
- MTW- Stranded Constructions Only
- RoHS Compliant
- LEED v4.1 Materials & Resources Credit MRc6; PBT (Lead Content Below 300 ppm Threshold)

* Ampacities based upon 2023 NEC Table 310.16 and do not take into account the overcurrent protection limitations in NEC 240.4(D) of 15 Amps for 14 AWG CU, 20 Amps for 12 AWG CU, and 30 Amps for 10 AWG CU (independent of the conductor temperature rating and stranding if size is present in table). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
* Inductive impedance is based on non-ferrous conduit with one diameter spacing center-to-center
