NEC Detailed Workshop

20 Continuing Education Credit Hours in NC (multi-state approved for varying credit)
Our 2 day Code Workshops offer each attendee the opportunity to work through each of the areas outlined below and more!

Code applications are reviewed in class, after which, each student has the opportunity to work multiple hands-on problem sessions to reinforce their strengths and uncover any additional needs in any area of study. These hands-on sessions fine tune the student’s code skills and show them exactly where they stand with respect to code accuracy, speed, and code book usage.

These workshops are serious but fun, and are intended for serious electrical students who want to be at their best in the electrical industry.
