30、cy and Standby PowerSystems, was prepared by the Technical Committee on Emergency Power Supplies and re-leased by the Correlating Committee on National Electrical Code. It was issued by theStandards Council on May 26, 2015, with an effective date of June 15, 2015, and supersedes allprevious editions
31、.A Tentative Interim Amendment (TIA) to Table 4.2.2 was issued on August 18, 2015.

32、merican National Standard on June 15,2015.Origin and Development of NFPA 111The Technical Committee on Emergency Power Supplies was organized in 1976 by NFPAin recognition of the demand for guidelines on the assembly, installation, and performanceof electrical power systems to supply critical and es
33、sential needs during outages of the normalpower source. During the development of a base standard (NFPA 110, Standard for Emergencyand Standby Power Systems), it was determined that several power sources were available foremergency and standby power systems. The committee determined that sufficient
34、differencesexisted between these sources to justify separate documents providing clearly defined specif-ics. Each document would follow the basic format of NFPA 110 to provide a consistent basisfor comparison and usage and would remain under the jurisdiction of the Technical Commit-tee on Emergency
35、Power Supplies.Because of the unique knowledge necessary to provide an authoritative document, thetechnical committee authorized a subcommittee in 1982 to prepare a draft document onsystems using stored energy sources. In 1986, a document tentatively titled NFPA 110A, StoredEnergy Emergency and Stan
36、dby Power Systems, was submitted for adoption at the 1989 NFPAAnnual Meeting.Formally designated as NFPA 111, this document addressed the performance of storedenergy systems with appropriate equipment detail. The requirements of the standard wereconsidered necessary to obtain the minimum level of re
37、liability and performance and toachieve an on-site stored energy auxiliary electrical power source suitable to the needs of theapplicable requirements. If followed, its use would result in a system suitable for varioussituations as required by other codes and standards.The second edition in 1993 con
38、tained only minor changes.For the 1996 edition, a section was added to cover the acceptability of systems, methods,and devices other than those listed in the document.The 2001 edition contained two changes: informational text was moved to the appendixand the operational testing requirements were exp
39、anded.The 2005 edition underwent a complete rewrite in accordance with the Manual of Style forNFPA Technical Committee Documents. Along with the rewrite, some of the definitions wererevised and located in Chapter 3. Other data in the document were transferred to the tableformat for better usability.
40、1111NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.The 2010 edition revised the document scope to clarify that an uninterruptible power supply (UPS) suppliedthrough an emergency power supply (EPS) is no
41、t a stored emergency power supply system (SEPSS). The definitions ofautomatic transfer switch and nonautomatic transfer switch were revised to correlate with NFPA 110. New definitionscovered battery cell types, bridging systems, and electrochemical energy storage devices. Energy sources, convertors,
42、inverters, and accessories were covered by Chapter 5 revisions that clarified existing requirements, recognized newbattery types, and provided requirements covering stored energy sources other than batteries. Revisions to area venti-lation requirements acknowledged that there might be flammable gase
43、s other than hydrogen associated with energysources that are not batteries. Annex diagrams were added to illustrate flywheel and rotating EPS systems, differentUPS systems, and basic switching points of an SEPSS.A rectifier plant, which is often used in the telecommunications industry, was added in
44、2013 as a potential storedemergency power supply system (SEPSS). These rectifier plants were also included as a suitable bridging system. Thelocation of SEPSS equipment serving Level 1 EPSS loads was revised to correlate with the requirements of NFPA 110.Throughout the 2016 edition, references to a
45、stored emergency power supply system have been revised to astored-energy emergency power supply system to more appropriately describe the type of system. Requirements forbaseline measurements have been revised to provide more accurate data. The load test has been revised to correlatewith the IEEE 45
46、0 rate-adjusted and time-adjusted capacity tests.1112 STORED ELECTRICAL ENERGY EMERGENCY AND STANDBY POWER SYSTEMS2016 EditionCorrelating Committee on National Electrical CodeMichael J.
