* Sizes 14, 12, and 10 AWG are available with Technology only in Barrel configurations. Standard put ups vary from the ones shown on this chart for standard 14-10 AWG THHN
+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
Application
- Fire alarm circuits and emergency lighting systems, where red color-coding ensures rapid response in critical situations.
- Control wiring in industrial machinery, such as automated assembly lines, for easy fault detection.
- Exit signs and building evacuation routes, leveraging the color’s prominence for enhanced safety in commercial buildings.
- Power distribution panels where red wires denote phase conductors in high-voltage circuits.
