3 THHN THWN-2 Stranded Copper Building Wire

Applications:

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. 600 Volts. Copper Conductor. PVC Insulation/Nylon Sheath THHN/THWN-2. Heat, Moisture, Gasoline and Oil Resistant II.

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

Also Known As:

3 copper wire, 3 building cable, 3 hook up wire, 3 conduit wire, 3 nylon wire, 3 construction cable, 3 thermoplastic-insulated copper wire, 3 THHN-PVC tray cable, 3 CU THHN THWN-2, 3 CU Building Wire, 3 Black Stranded CU SIMpull THHN Wire

Construction:

Conductor: 

THHN THWN-2 conductors are constructed of annealed soft copper that follows ASTM B3 and ASTM B8 standards. 

Insulation:

The cable is insulated with a thermoset plastic jacket (PVC) that is flame-retardant, sunlight-resistant, lead-free, strong, and stable. Without being too bulky, it ensures that the cable can be used in harsh conditions. The jacket is color-coded in accordance with ICEA Method 4.

Sheath:
