Southwire SIMpull® THHN/THWN-2 copper conductors are primarily used in conduit and cable trays for services, feeders, and 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. SIMpull® THHN/THWN-2 copper conductors are designed to be installed without the application of a pulling lubricant. 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-2: Wet 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
