Study Lesson 6 flashcards. Create flashcards for FREE and quiz yourself with an interactive flipper.According to the NEC, nominal conductor ampacity at 30°C is determined by the conductor material (copper or aluminum), size, insulation type, and application (direct burial, conduit, or free air). In NEC, table 310.15(B)(16) (formerly 310.16) is used to look up the ampacity rating for any conductor. Ambient Temperature DeratingSee Figure 6 for the different diameters of a 4/0 AWG conductor with four different insulation types. Table 5 from Chapter 9 of the NEC gives the approximate diameters and areas of different types of conductors, a portion of which is presented as Table 7 in this document, which shows THHW, THHN, THWN, and XHHW.These markings provide important information about the wiring and insulation, including the wire size and material, the type of insulation, the number of wires contained (inside a cable), and any special ratings or characteristics of the wire. ...
