This is a guide for electrical engineers working in the field of designing electrical services, power distribution and lighting systems. This book describes the design process and the engineer's role on the building design team within the construction industry and includes up-to-date codes, standards, and practices. Unlike any other book in this area, this book provides thorough engineering guidance in the context of the actual design process. The intent of this book is to guide engineers through the various aspects of designing a building's electrical system. It will also help improve their understanding of how to successfully complete a project on schedule, within budget, and avoid errors and omissions in the engineering drawings and specifications.
