It's that time again... the time we all know so well every three years when electrical professionals everywhere usher in a new Code change cycle. Whether they face these revisions with great anticipation, overwhelming excitement, or even a little bit of reluctance or anxiety varies.

That's why we've teamed up with longstanding NEC Consultant Mike Holt once again 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.
