NATIONAL ELECTRICAL CODES (NEC 2008)

Ref No: 2015056

COURSE DESCRIPTION

On March 18-19, 1896, a group of 23 persons, representing a wide variety of organizations, met at the headquarters of the American Society of Mechanical Engineers in New York City. Their purpose was to develop a national code of rules for electrical construction and operation. By 1895, five electrical installation codes had come into use in the United States, causing considerable controversy and confusion. It was difficult to manufacture products that met the requirements of all five codes. Something had to be done to develop a single, national code. The committee that met in 1896 recognized that the five existing codes should be used collectively as the basis for the new code. Before the committee met again in 1897, the new code was reviewed by 1200 individuals in the United States and Europe. Shortly thereafter, the first standardized U.S. electrical code, the National Electrical Code®, was published.
The National Electrical Code has become the most widely adopted code in the United States – it is the standard used in all 50 states and all U.S. territories. Moreover, it has grown well beyond the borders of the United States and is now used in numerous other countries. Because the code is a living document, constantly changing to reflect changes in technology, its use continues to grow.
This course is designed to teach electrical and instrumentation personnel how to read and interpret the meaning of the NEC©, and how to find information in the Code Book the easy way. This course is a "must take" for those working in the residential, commercial, or industrial electrical industry. The course uses Delmar Publishers' current edition of Interpreting The National Electrical Code© as its textbook, which is organized into 15 easy-to-understand units covering each subject addressed in the Code Book. Each Article of the Code is thoroughly discussed and reviewed in easy-to-understand language. The ultimate objective of the course is for the participant to develop or enhance their working knowledge of the NEC by learning how to find and understand the information presented in the code. We will teach you how to find the rules that apply to your facility, and we will answer your code questions. Further, we will discuss the style and layout of the 2008 NEC Code and how they can be applied in your facility.

COURSE OBJECTIVES

Upon the successful completion of the course the participants should be able to:
1- Understand the layout of the 2008 National Electrical Code.
2- Understand the relationship between the National Electrical Code and the National Electrical Safety Code.
3- Differentiate between NEC and OSHA examination, installation and use requirements.
4- Understand the proper locations for electrical equipment to provide for proper working clearances and free space requirements.
5- Determine proper methods of identification for grounded conductors, grounding conductors, and multiwire branch circuits.
6- Understand installation requirements for services.
7- Understand bonding and grounding requirements for services, feeders, branch circuits, and utilization equipment.
8- Select the proper size and location of overcurrent protection for various types of utilization equipment.
9- Be knowledgeable of requirements for temporary wiring and GFCI applications.
10- Be knowledgeable of acceptable wiring methods and materials including recent changes in acceptable industrial wiring methods and materials.
11- Select the proper size of raceway, fitting, and boxes including wire bending space, component sizing and conductor identification.
12- Size motor circuits and required components according to recent code changes.
13- Understand transformer installations including various types of delta and wye connections.
14- Understand acceptable wiring methods for hazardous (classified) locations.
