|
| APPLICATIONS |
|
| SIMpull® CU THHN/THWN(-2) 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. Voltage for all applications is 600 volts. SIMpull® conductors are designed to be installed without 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 |
|
• | 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 |
|
|
|

| CONSTRUCTION |
|
| SIMpull® CU THHN/THWN(-2) conductors are made with soft drawn copper. Sizes 14 through 4/0 AWG use a combination-unilay stranding while 250 kcmil and larger sizes use a compressed copper stranding. The wire is covered with a tough heat and moisture resistant PVC insulation with an overall nylon jacket utilizing SIMpull® Technology. Available in black, white, red, blue, purple, green, yellow, orange, brown, and gray. Also available in striped configurations. Some colors are subject to economic order quantity. |
| Marked as THHN in all sizes. Also marked as THWN-2 in sizes 8 AWG and larger or marked as THWN in sizes 14, 12, and 10 AWG. Marked sunlight resistant in sizes 2 AWG and larger. Sizes 14, 12, and 10 AWG are available with SIMpull® Technology only in SIMpull® Barrel or CoilPAK® configurations. |

| + Allowable ampacities shown are for general use as specified by the 2014 Edition of the National Electrical Code Sections 310.15 and 240.4(D). Unless the equipment is marked for use at higher temperatures the conductor shall be limited to the following per NEC 110.14(C): |
| 60°C - When terminated to equipment for circuits rated 100 amperes or less or marked for 14 - 1 AWG conductors. |
| 75°C - When terminated to equipment for circuits rated over 100 amperes or marked for conductors larger than 1 AWG. |
| 90°C - THHN dry locations and THWN-2 wet or dry locations for ampacity adjustment purposes using NEC section 310.15. |
