The National Electrical Code® (NEC) continues to be the most important topic to EC&M readers. That's why we've teamed up with longstanding NEC Consultant Mike Holt to bring you the key changes made during the latest Code cycle. In order to make these comprehensive changes more manageable and easier to digest, we've created this gallery, which summarizes the most important revisions to the 2020 NEC that affect the largest number of our readers. Scroll through the photo gallery for short summaries of each change.

Editor’s Note: The information presented in this gallery is based on Mike Holt's full 2020 National Electrical Code Changes article, which ran in the November 2019 print issue of EC&M magazine.
