Specifications include, but are not limited to: Develop accurate one-line drawings that identify equipment voltage levels, sources, tie breakers, and various system configurations that impact hazard calculations. These drawings should be suitable for planning purposes to determine back feeds and energized sources. B.Perform field data collection of electrical equipment nameplate parameters. These parameters in conjunction with appropriate software are to provide a comprehensive model and database of the electrical system to perform all types of analysis. C.Perform short circuit and equipment duty calculations to ensure all equipment is properly rated to withstand and interrupt the available short circuit current. D.Perform protective device coordination (circuit breakers, fuses, protective relays, etc.) to ensure that each device will operate properly on the available bolted and arcing short circuit current.
