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.

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.
Day 1
You get to learn about the basic flow and navigation of the National Electrical Code & National Fire Alarm and Signaling Code Books. You will be “reintroduced” to these references by relating common slang terms to the formal terminology. The instructor helps connect real life situations to these references so that students are more comfortable and familiar with utilizing their NEC and NFPA.
Learning Objectives
- Students will learn correct terminology used in the NEC and NFPA.
- Students will learn the arrangement of the NEC and NFPA in order to locate needed information.
- Students will practice calculations and relate these calculations to the NEC.
