IEEE-1584 requirements. The dimensions of the enclosures and the worst case electrode configurations will be displayed in the arc flash results table. o As mentioned previously the models will be set up with multiple scenarios for the worst case scenario incident energy for each equipment. o Decrement curve method will be used in case of calculating the incident energies from the generator sources using the dynamic characteristic impedances of the generators. o Single phase circuits/devices will be calculated separately for the incident energies and combined to the final report. o All the scenarios will be listed with notes in a table in the report so they can be easily identified. o Arc flash results will be presented in the report in a tabular format displaying the incident energy with the existing device settings next to the incident energy results based on the recommended device settings. Client will be easily able to identify the differences. o The results will be color coded in the arc flash table based on the following: ■ Incident energy results > 40cal/cm2— magenta color ■ Difference between incident energies of the existing vs. recommended settings — blue color ■ Fault clearing time capped at 2 sec — yellow color o For each identified issue for the arc flash results, recommendations or solutions there will be an individual note at the bottom of the table. o All problems, recommendations and solutions will be presented in the executive summary section of the report. o Adjustments or approximation will be considered upon City of Santa Ana's approval in case the information needs to be assumed. Labels will be generated and printed based on the City of Santa Ana formatting requirements. 4.5.Study Report The study report is comprised of different sections which includes the following: o Revision History: includes the information regarding the revisions made to the original report o Table of contents o Executive Summary: which includes the results and recommendations in a tabular format individually color coded for each study section. Each presented table displays a short memo of the finding including any code violations, equipment type/ID, location of the equipment for fast locating, description of the issue or finding and the recommendations. Depending on the finding a phot of the equipment and/or its conditions will be attached to that table. Below is a sample of the above description:
