2014 NEC Changes - Chapter 3: Wiring Methods and Materials

This is the third of several courses covering the changes in the 2014 edition of the National Electrical Code® (NEC®) created by the NFPA®. The 2014 NEC provides an accurate, reliable, and authoritative account of the hundreds of significant revisions in the 2014 Code.

 

This Course provides coverage of significant changes in the 2014 National Electrical Code®. With every new edition of the NEC, some of the changes include new requirements to sections, while some of the changes include entirely new articles. Some changes are revisions to existing requirements while others are deletions to some existing requirements.

 

Chapter 3 covers wiring methods and materials, and provides some very specific installation requirements for conductors, cables, boxes, raceways, and fittings. This chapter includes detailed information about installation and restrictions involved with wiring methods. The chapter begins with rules that are common to most wiring methods, it then covers conductors and enclosures. The articles that follow become more specific and deal in more depth with individual wiring methods such as specific types of cables and various raceways. The chapter winds up with article 392, a support system, and the final articles for open wiring.
