The National Electrical Code (NEC) and Its Applications

The course will be taught from the perspective of a consulting/specifying engineer, however, the material covered will benefit individuals involved in a wide range of employment positions; from the technician doing installations and/or maintenance to the engineer designing AC powered equipment, a working knowledge of the code is essential.  We will explore all aspects of the code starting with a brief history of the code and discuss how it has evolved into its current issue NFPA 70 2014.  Even though the current version of the NEC is 2014, each municipality may choose which version they will adopt. In New York City we follow the 2008 version of the NEC and as such this is the version that we will focus on. The course will concentrate on establishing a firm grasp of the definitions contained in the code, as it is crucial to understand what the code actually says. We will then progressively work through the articles covering everything from general wiring and protection, wiring methods, and life safety to special conditions and occupancies.  Along the way, we will work through numerous calculations to determine feeder sizes, voltage drops, conduit fill, etc. and learn how to utilize the many tables contained within the code.  Exercises involving building plans will be used to help the student apply his knowledge to actual real world conditions.  While the course is not an exam-prep per se, one wishing to pursue a master’s electrician’s license or a professional engineer’s license, should be better prepared upon completion of the course.

  • Founded by inventor, industrialist and philanthropist Peter Cooper in 1859, The Cooper Union for the Advancement of Science and Art offers education in art, architecture and engineering, as well as courses in the humanities and social sciences.

  • “My feelings, my desires, my hopes, embrace humanity throughout the world,” Peter Cooper proclaimed in a speech in 1853. He looked forward to a time when, “knowledge shall cover the earth as waters cover the great deep.”

  • From its beginnings, Cooper Union was a unique institution, dedicated to founder Peter Cooper's proposition that education is the key not only to personal prosperity but to civic virtue and harmony.

  • Peter Cooper wanted his graduates to acquire the technical mastery and entrepreneurial skills, enrich their intellects and spark their creativity, and develop a sense of social justice that would translate into action.
