This interactive online course covers the changes in Articles 242 and 250 of the National Electrical Code®. The new article 242 contains the requirements for overvoltage, or surge, protection. Article 250 covers the grounding and bonding of systems and equipment. Notable changes include the creation of Article 242 and deletion of Article 280 and 285, a new section addressing the bonding of equipment on the line side of the service, specific requirements for aluminum conductors, limiting the role of rebar in the grounding electrode system, fixing an error about the sizing of bonding jumpers, reducing the identification requirements for equipment ground conductors, and providing relief for the sizing of equipment grounding conductors in certain applications.

NOTE: Discounts will display at the very end of the checkout process.
