National Electrical Code

Online Attendance: Registration closes 5 business days before course starts

The NEC® is the foundation for safe electrical installations in the U.S. Understanding the NEC structure, revision updates, and application is essential for professionals in design, installation, and inspection. This course, led by a nationally recognized NEC® expert, covers key topics such as grounding, overcurrent protection, wiring methods, and service requirements. Participants will gain the skills to design, install, and inspect code-compliant systems, avoid costly mistakes, and stay informed on the latest code changes and interpretations.

I enjoyed the willingness of the instructor to share detailed experiences of his related to code and installation challenges. He was very knowledgeable and took his time teaching, often injecting humerus comments into what some would consider a very dry subject… really appreciate the time taken by the instructor and program director in making this course as enjoyable as possible as well as comprehensive… I would definitely sign up for another course taught by Noel in the future if the opportunity presented itself.
— Stefen LeClair (In-Person attendee)
I really appreciated the interactive elements, such as the quizzes, polls, and the overall emphasis on engaging students. These activities helped reinforce the material in a fun and memorable way. The group activities were also of excellent quality—well-organized and thought-provoking, which encouraged collaboration and deeper understanding. Additionally, the material covered was comprehensive, providing a solid foundation on key concepts.
