Construction:

Conductor: Solid sizes #14 AWG - #10 AWG use soft drawn bare copper per ASTM B3. Stranded sizes #14 AWG - #10 AWG use a combination-unilay stranded soft drawn bare copper per ASTM B787.
Insulation: Heat and moisture resistant PVC
Sheath: Nylon

Applications and Features:

APPLICATION
Southwire® THHN copper conductors are primarily used in conduit for 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. 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- Wet locations not to exceed 75°C 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

Gasoline and Oil Resistant II

† 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). Also, see NEC sections 310.15 and 110.14(C) for additional requirements.
