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
