![]() ![]() ![]() Both of them have high heat resistance and can function adequately in temperatures us to 90C or 194F. 12/2 Metal Clad (MC) Cable with Aluminum Armor and Copper Conductors (1000 Feet) 36 24327 - 1,14226 Southwire Aluminum Cable Thhn 12/2 Ga 250 B/W/Green. In high heat situations, however, you would do much better going with high heat wires like THHN or THWN-2. NOTE: The data shown is approximate and subject to standard industry tolerances. High Heat Situations (Above 75C or 167F) If you expect the heat to be below 75C or 167F, you can use any of these wires. Wires are labeled with the THHN/THWN, material. Basically, THWN stands for, Thermoplastic Heat and Water. However, it only had 2 wires going into it: a red one and a white one: Furthermore, for some reason. ![]() The difficulty in differentiating the two electrical wires is quite understandable considering that they share a lot of similarities. THHN wire can be used in dry or damp locations where wire is exposed to condensation or moisture, such as a basement. Frequently Asked Questions About 4 AWG THHN THWN-2 Wire 28 Stranded 14 Black & 14 Red 600V Insulated Copper in My Website. †The overcurrent protection for items marked with an obelisk (†) shall not exceed 15 amps for #14 AWG, 20 amps for #12 AWG, and 30 amps for #10 AWG per NEC 310-17 footnote. Overview Southwire's SIMpull THHN is primarily used in conduit and cable trays for services, feeders and branch circuits in commercial or industrial applications. What is the difference between THW and THWN Wire Most people often find it difficult to differentiate between a THW wire and a THWN-type Wire. *Based on ambient temperature of 30☌ per NEC Table 310.15 (B)(17). ![]()
