Power generation units are now indispensable in modern construction facilities of all kinds. This book helps to consolidate the multitude of different standards, laws, and regulations. In addition to considering the current standardization situation, this third edition includes new chapters on "Risk Analysis and Safety" and "Periodic Inspections." Alongside purely electrical aspects, such as power sizing, control, energy distribution, compliance with safety measures, and selectivity, other concerns are also addressed, including building code requirements for the design of the installation space, fire protection requirements, fuel supply, and exhaust.
