IEEE Standard 446 - The Orange Book Working Group

Recommended Practice for Emergency and Standby Power Systems for Industrial and Commercial Applications


This standard presents recommended engineering principles, practices, and guidelines for the selection, design, installation, application, operation, and maintenance of emergency and standby power systems. This information is primarily presented from a user's viewpoint; however, managing the effects of power system disturbances requires close cooperation between users, electric utilities, and equipment manufacturers.
