2017 NEC Changes: Conductors and Wiring Methods
Chapter 3 of the 2017 National Electrical Code contains requirements for conductor sizing and wiring methods. Several changes were made in Article 310 and the articles covering cable and raceway wiring methods [320-399]. In this interactive, online course, we will discuss several changes in Chapter 3 including 310.15(A)(2) Selection of Ampacity, 310.15(B)(3)(c) Raceways and Cables Exposed to Sunlight on Rooftops, and 310.15(B)(7) Single-Phase Dwelling Unit and Feeder Service Conductors. We will discuss the listing requirements in the Chapter 3.6 section and the .30 sections for securing and supporting throughout chapter 3. We will also examine 336.10 Uses Permitted for (TC cable) or tray cable and 338.10(B)(4)(a) Uses Permitted for service entrance cable or (SE cable), and review 344.14 Dissimilar Metals in Rigid Metal Conduit Systems (RMC). Other topics covered in the course include 350.28 Trimming of Liquidtight Flexible Metal Conduit (LFMC), 358.10 Uses Permitted for EMT. 376.20 Conductors in Parallel for Metal Wireways, and 392.22(A), which covers the number of conductors in (cable trays).
