A. This Section includes packaged engine-generator sets suitable for use in emergency standby applications with the features as specified and indicated. Engine generators will be used as the standby power source for the system, and shall be capable of providing reliable power with no runtime limitations while the primary source of power is unavailable. B. Provide a new diesel engine-driven standby generator system to supply the standby power to the building electrical system as indicated on the Drawings and schedules. This system shall be a NFPA 110 EPSS, Class 24, Type 60, Level 2 system. C. Provide unit mounted in an all-weather sound enclosure with a unit mounted exhaust systems with a critical muffler. Provide manufacturer recommended vibration isolation for engine- generators including pads, springs, rails, bases, hangers, and connectors. D. Provide generator engine fuel tank integral with the skid base and having capacity to fuel engine for minimum 24 hours at 100% rated output, or 500 gallons minimum, whichever is greater. E. Provide a unit mounted main circuit breaker to prevent overloading of the generator and power supply conductors. F. Provide a complete and fully operational standby power generation system including all engine fueling, heat rejection, starting and operation controls and safeties, voltage regulation, output breaker, etc. 1.2 QUALITY ASSURANCE A. Manufacturers: Firms regularly engaged in the manufacture of engine-driven standby generator systems, of types, ratings and characteristics required, whose products have been in satisfactory use in similar service for not less than 10 years. B. Source Limitations: Obtain packaged generator sets and auxiliary components through one source from a single manufacturer. C. NEC Compliance: Comply with applicable standby generator requirements of NEC including, but not limited to, emergency and standby power generating systems. D. NFPA Compliance: Comply with applicable requirements of NFPA 37, "Installation and Use of Stationary Combustion Engines and Gas Turbines", and NFPA 110 requirements for standby power supply system. E. ANSI/NEMA Compliance: Comply with applicable requirements of ANSI/NEMA MG 1, "Motors and Generators", and MG 2, "Safety Standard for Construction and Guide for Selection, Installation and Use of Electric Motors and Generators". F. IEEE Compliance: Comply with applicable potions of IEEE Std. 241, "IEEE Recommended Practice for Electric Power Systems in Commercial Buildings" pertaining to standby power.
