This course is Part 2 of a 3-Part Series intended to familiarize the reader with the major changes contained in the 2014 National Electrical Code®. These are the "need to know" changes. The document is heavily illustrated to enable effective and efficient visual learning. The course addresses Code revisions that apply to all types of occupancies: residential, commercial, and industrial. The 3 parts of the Course Series are:
- Part 1: Code-wide changes through Article 240
- Part 2: Article 250 through Article 424
- Part 3: Article 445 through Informative Annex J
The layout and the method of this presentation will enable new Code users to easily navigate through the changes. Those well experienced in the Code will find depth in the coverage.
Through the heading(s) at the beginning of each Code change addressed in the document, the reader will readily identify the section affected by the change and the specific subject being discussed. The Significance section serves as an introduction to the Code change under discussion. An Analysis of the Code change follows, with explanation where necessary to help the student understand the revision, its background, and the logic of the change. Graphics, photographs, examples, or calculations are used to illustrate the change and to enhance learning.
The Summary is a brief re-instatement of the highlights of the Code change. An Application Question, with Answer and key to the correct answer, is included at the end of each Code section studied for exercise in applying the change and to broaden learning. Many of the sections analyzed contain a Code Refresher that addresses existing Code requirements related to the change. The author attempts to tie the entire NEC® together through the study of the changes, Code Refreshers, Technical Updates, Examples, and Application Questions.
Although there are many references to the 2014 NEC throughout this document, the course and quiz can be completed without the need to refer to the NEC itself. However, the learning experience will be enhanced by referring to the NEC as the course is completed. For further study on any Code section within this course, the 2014 NEC should be consulted.

- The new table in NEC for sizing supply-side bonding jumpers and certain grounded conductors
- An additional method for providing an equipment grounding conductor to enhance the safety of older ungrounded wiring
- Ground-fault detection systems for ungrounded dc systems
- New requirements for grounding of systems and circuits above 1,000 volts
- New requirements for cable ties and other nonmetallic cable accessories used for securing and supporting cables installed in air-handling spaces
- Revision of the methods for determining reduced conductor sizes for services, feeders, and branch circuits where a low demand factor or diversified load existed
- Additional permission for unsupported Type MC cable when flexibility is required to minimize transmission of vibration from equipment
- Clarification of the 30 conductor threshold for metal wireways
- Wiring methods permitted in cable trays
- Cable tray marking requirements
- Updated rules for installation of low-voltage suspended ceiling power distribution systems and equipment
