Are you up to code? This interactive online course covers the changes in Articles 240, 242, 245, and 250 of the 2023 National Electrical Code®. In this course, we’ll discuss the protection of conductors, standard ampere ratings, listing requirements, selective coordination, interrupting ratings, location on-premises, and replacement trip units. Additionally, we’ll review objectionable current, explain the revision to impedance-grounded systems, and define impedance-grounded systems.
