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 90C
– THWN- Wet locations not to exceed 75C or dry locations not to exceed 90C or locations not to exceed 75C when exposed to oil
– TWN75- Wet locations not to exceed 75C
– MTW- Wet locations or when exposed to oil at temperatures not to exceed 60C or dry locations not to exceed 90C (with ampacity limited to that for 75C conductor temperature per NFPA 79)
– AWM- Dry locations not to exceed 105C only when rated and used as appliance wiring material
