Application & 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
  • VW-1 Sizes 14 through 10 AWG
  • FT1 All Sizes
  • AWM- Sizes 14 through 10 AWG
  • MTW- Stranded Constructions Only
  • RoHS Compliant
