60ºC - When terminated to equipment for circuits rated 100 amperes or less or marked for conductor sizes 14 through 1 AWG. For MTW in wet locations or when exposed to oil or coolant.75°C - When terminated to equipment for circuits rated over 100 amperes or marked for conductors larger than size 1 AWG. THWN-2 when exposed to oil or coolant.90°C - THHN dry locations. THWN-2 wet or dry locations. For ampacity derating purposes.Available colors: Black, White, Red, Blue, Green, Yellow, Brown, Orange, Purple, Gray, Pink.Notes:• Where stated, “nominal” and “approximate” values are provided for information purposes only and are subject to standard manufacturing tolerances.• Ampacities are in accordance with NEC 2008 and NEC 2011 Article 310.15, which are based on NEC 2008 Table 310.16 or NEC 2011 Table 310.15(B)(16) for conductors in a raceway or direct buried at 30°C ambient temperature.• For correction factors for different ambient temperatures and ampacities at different conductor temperature ratings see NEC 2008 Table 310.16 or NEC 2011 Table 310.15(B)(16).• NEC 2008 and NEC 2011 Article 240.4(D) requires that overcurrent protection not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG copper conductors after any correction factors for ambient temperature and number of conductors have been applied. Exceptions to this may be covered in NEC 2008 and NEC 2011 Article 240.4(E) through (G).
* Only stranded cables are MTW listed per UL 1063.
