The National Electrical Code Style Manual has been in existence since 1969 and has been updated nine times since its inception. There was quite a bit of activity in the 2020 NEC® concerning definitions. In part one of this part-part, interactive online course we will cover new definitions added, and existing definitions that have been revised or relocated in the 2020 NEC®. We will also review new and revised requirements for equipment installation, labeling, marking and working space.
