Exam Preparation/Detailed NEC Workshop

Exam Preparation = Both days

Continuing Education = Day 1, Day 2, or Both days

Our Detailed NEC Workshop is focused for those preparing for their state license and will cover what you need to know for your electrical examination. Those preparing for their state exam will be attending both Day 1 and Day 2.

Exams in NC are on the 2020 NEC as of March 1st, 2022

NEW Examination Guidelines for North Carolina

Currently licensed electricians should be aware that this class is focused on the current code that the state is testing on and may not provide current practices in the field.


This is our comprehensive course on the National Electrical Code.

The emphasis is on taking concepts and applications in the code and breaking it down for electricians to use efficiently and effectively. These hands-on sessions fine tune the student’s code skills and show them exactly where they stand with respect to code accuracy, speed, code book usage, and calculations. These workshops are serious but fun, and are intended for serious electrical students who want to be at their best in the electrical industry.
