Course Overview

Learn about the 2020 National Electrical Code® (NEC) from a nationally known NEC expert, author, and speaker.

The National Electrical Code® is the "benchmark for safe electrical design, installation, and inspection to protect consumers and property from electrical hazards," according to the National Fire Protection Association. This course is organized to help you design, install, or inspect more efficiently by applying the 2020 National Electrical Code to your daily work. Upon completion of the course, you will be able to design electrical systems that are code compliant, having an awareness of the liabilities associated with noncompliance.

This course also discusses how the NEC is organized, changes from previous editions, requirements for new and existing installations, "how-to-design" information for electrical systems, and valuable information on how the NEC relates to other standards.

Testimonials

"(I was) looking to understand the NEC to pass the PE exam...Good mix of presentation and examples...Great choices on (which) topics to cover. Good activities to help aid in learning the material."
—Gina M., Power Engineers; Nov 2019

"The in-depth coverage of various NEC articles and practical examples of when exceptions apply gives much better familiarity of the code than I previously had."
—Scott C., Kapitan Engineering; Nov 2018

"It was a thorough review of the most important parts of the NEC, from the service to the loads."
—Dan G., Power Distribution Equipment Company; Nov 2018
