McPartland the Handbook analyzes the many changes in the Code and offers practical advice to help anyone involved in electrical design, installation or maintenance to understand provisions that need clearer explanations and interpretation. It provides the know-how necessary for a thorough understanding of what must and must not be done in electrical work in order to comply with all Code rules exactly and past inspection the very first time, every time. New to the Handbook and this 21st edition is a new article covering requirements for multi-building facilities. Also included is coverage of additional requirements for the proper use of a wide range of equipment and conductor used for residential, commercial, industrial,and institutional electrical systems.
