2008 National Electric Code
Thomas Mason, PE
The course exactly follows the structure of the 2008 National Electrical Code (with some digressions to connect related rules). The Preface, Introduction and Definitions are explained as very special parts of the code, with detailed discussion of the rules beginning in the Definitions section.
Requirements for electrical installations, ground conductors and grounding, feeders and branch circuits, services, overcurrent protection, surge protection devices, conductors, industrial control panels, transformers and reactors, low-voltage wiring and data communications are addressed. Residential design and fine points of specialized areas, such as electrical processes are not addressed. Examples are given from waste water treatment plants and general manufacturing.The course is also available in audio (.mp3) format E260U and live-online webinar ™ format E260W.
The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
At the conclusion of this course, the student will:
This course is intended for project managers, electrical engineers, engineers and Architects who work with electrical engineers and contractors who must deal with electrical inspectors.
Benefit to Attendees
It is the job of electrical designers to meet the sometimes peculiar requirements of the National Electrical Code. This course is intended to help them be aware of the requirements, how they are generally interpreted and, just a little, how to meet them. Project managers, architects and supervisors need a passing understanding of the mindset of the National Electrical Code and some recent problems with inspectors that can be avoided. Contractors are always looking for more economical ways to complete a project. This course helps focus on problem areas, but it is not a design guide.
This three hour online course reviews the 2008 version of NFPA 70, the National Electrical Code, in common English. Because the book is so massive, only topics found critical or difficult to understand in the author’s experience are included. Other content of the Code is indicated, but not pursued. The presentation follows that in the Code and sections discussed are cited.
You must have access to a copy of the2008 National Electrical Code to checkthe exact wording of requirements for your immediate design and construction questions. It is not intended that a copy is needed at your computer when you takethis course and quiz.

This course attempted to review new and critical sections of the 2008 National Electrical Code. It did not include exercises in calculating the minimum size for junction boxes, based upon number and size of conductors. Unfortunately, space was not available to review many of the very basic principles which have not changed for many, many revisions, such as sizing motor circuits and motor controls. Fortunately, though, PDHonline.com offers a wide range of electrical courses which do address these needs. After you have recovered from the current exercise, please spend a few minutes reviewing the other PDHonline.com courses available.
