City of Everett 26 05 73.16 - 1 <br /> Inductive Charging Infrastructure for Everett Transit <br /> SECTION 260573.16 - COORDINATION STUDIES <br /> PART 1 -GENERAL <br /> 1.1 SUMMARY <br /> A. Section Includes: <br /> 1. Computer-based, overcurrent protective device coordination studies to determine <br /> overcurrent protective devices and to determine overcurrent protective device <br /> settings for selective tripping. <br /> a. Study results must be used to determine coordination of series-rated <br /> devices. <br /> B. Related Requirements: <br /> 1. Section 260010 "Supplemental Requirements for Electrical" for additional <br /> abbreviations, definitions, submittals, qualifications, testing agencies, and other <br /> Project requirements applicable to Work specified in this Section. <br /> 2. Section 260573.13 "Short-Circuit Studies" for fault-current studies. <br /> 3. Section 260573.19 "Arc-Flash Hazard Analysis"for arc-flash studies. <br /> 1.2 DEFINITIONS <br /> A. Existing to Remain: Existing items of construction that are not to be removed and that <br /> are not otherwise indicated to be removed, removed and salvaged, or removed and <br /> reinstalled. Existing to remain items must remain functional throughout construction <br /> period. <br /> B. One-Line Diagram: A diagram that shows, by means of single lines and graphic <br /> symbols, the course of electric circuit or system of circuits and the component devices <br /> or parts used therein. <br /> C. Protective Device: A device that senses when abnormal current flow exists and then <br /> removes the affected portion of the circuit from the system. <br /> D. SCCR: Short-circuit current rating. <br /> E. Service: The conductors and equipment for delivering electric energy from the serving <br /> utility to the wiring system of the premises served. <br /> F. Single-Line Diagram: See "One-Line Diagram." <br /> 1.3 ACTION SUBMITTALS <br /> A. Product Data: <br /> 1. For power system analysis software to be used for studies. <br /> 26 05 73.16 - 1 COORDINATION STUDIES <br />
