When designing generator power systems, electrical engineers must ensure that the generators and the building electrical systems that they support are appropriate for the specific application. Regardless of the application, engineers must make decisions regarding generator sizing, load types, whether generators should be paralleled, fuel storage, switching scenarios and many other criteria. In addition to being up to speed on the applicable codes, consulting engineers must work with the authorities having jurisdiction to ensure approval for the generator system is attained.

Learning objectives:

• Understand the fundamental generator system classifications outlined in NFPA 37: Standard for the Installation and Use of Stationary Combustion Engines and Gas Turbines, NFPA 70: National Electrical Code and NFPA 110: Standard for Emergency and Standby Power Systems.
• Know about the basic criteria for selecting the appropriate generator for the building type and/or application.
• Get an overview of application considerations including location and fuel sources.
• Understand areas for coordination with other members of the design team including structural, mechanical, fire protection and architectural systems.
