Revisions for the 2020 National Electrical Code (NEC) - Part 3 (Ohio Timed & Monitored)

In Revisions for the 2020 National Electrical Code - Part 3, you'll learn ...

• The “need to know” changes in the 2017 National Electrical Code®
• How to use the Code and many of the existing requirements in the Code
• Article 600 through Informative Annex D

Overview

To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 150 minutes has been met.

This course series is intended to familiarize the reader with the major changes contained in the 2017 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 course is divided into 3 parts:

• Part 1: Code-wide changes through Article 250
• Part 2: Article 300 through Article 590
• Part 3: Article 600 through Informative Annex D

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-statement of the highlights of the Code change. An Application Question with Answer and key to the correct answer is included at the end of most Code sections studied for exercise in applying the change. Less significant changes are addressed in less detail. Some of the sections analyzed contain a Code Refresher that addresses existing Code requirements related to the change, and general Code information and rules are weaved into the writing throughout the document. The author’s writing method attempts to provide general Code study and a Code refresher through discussion of the Code changes. NFPA 70E®, Electrical Safety in the Workplace, is briefly discussed and referenced several times within the course.

Although there are many references to the 2017 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 full text of the 2017 NEC® should be consulted.
