WebCalculate, using a 90°C conductor such as THHN: 250 kcmil copper has a 90°C ampacity of 290 A. Using the factors noted earlier: 290 x 0.80 x 0.91 = 211 A. 211 A is less than 75°C ampacity of a 250 kcmil copper conductor (255 A), so the 211 A would now be the allowable ampacity of the 250 kcmil conductor. WebTHHN stands for Thermoplastic High Heat-resistant Nylon-coated. THWN wire is the same, but the "W" stands for water-resistant. The main difference between these two standards is their maximum temperature in wet locations. 5. 7 What type of wire is commonly used in building wiring installation? a. THHN/THWN b UTP c. AGP d. WebYears ago, you could buy THHN, THWN, THW, THHW or THWN-2 wires, each one made for a specific installation, but now we use multi-rated THHN/THWN-2 as a universal building wire.
