CONSTRUCTION:

1.      Conductor: Solid sizes 14 - 10 AWG use soft drawn annealed bare copper per ASTM B3. Stranded sizes 14 - 10 AWG use combination-unilay soft drawn annealed bare copper per ASTM B3 and B787.

2.      Insulation: Heat and moisture resistant Polyvinyl Chloride (PVC)

3.      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
