I first wrote this course in 1990 at the request of the State of Alaska Department of Labor.  At that time many mechanical contractors were moving from pneumatic controls to electronic controls and were  installing their own control wiring subject to the rules found in the National Electrical Code.  This became a problem when State Electrical Inspectors inspected these systems and observed an unusually high number of nonconforming items, and I was one of those inspectors.  A commitment was made by the Department of Labor to train mechanical contractors on pertinent rules found in the National Electrical Code.  That promise resulted in this course.  Since 1990 I have revised this course four times to keep abreast of the NEC revisions that are published every three years.  This current revision, revision No. 5,  is much more extensive than previous versions because I have had the fortunate experience of performing electrical wiring for a major Control Contractor specializing in HVAC and process controls for the last year and one half.  This experience has increased my field knowledge of control wiring and allowed me to work with some very fine control installers, programmers, and engineers.

This course is for anyone doing control wiring subject to the National Electrical Code and is an excellent introduction to the National Electrical Code for Mechanical Contractor persons that are required to perform electrical control work in accordance with the NEC.
