This book is a 20-page practical guide systematically summarizing the essential BCP measures for power supply that Japan's manufacturing industry, which frequently faces typhoons, earthquakes, and floods, needs to ensure "operations do not stop due to power outages." Starting with the basics of BCP/BCM, it explains preparations for the most significant obstacle during disasters, "power outages," using abundant illustrations and the latest data (from the Small and Medium Enterprise Agency White Paper and Cabinet Office surveys). Additionally, it clearly organizes the selection points for emergency generators, industrial storage batteries, and high-current cam switches, and includes specifications compliant with IEC60947-3/JIS C8021-3 and layout examples for transfer panels. Furthermore, it introduces four case studies on "construction equipment rental," "building materials manufacturers," "solar power equipment," and "UPS maintenance," presenting the challenges and effects before and after implementation in a quantitative manner. After reading, you will have a concrete action plan that clarifies "which equipment should be prioritized for recovery in your company," "how to shorten power outage recovery times through wiring and switch configurations," and "how to outline a phased implementation procedure that minimizes costs and space." This content is beneficial not only for design and maintenance engineers who are in a hurry to formulate BCP but also for purchasing, production management, and management levels.
