The analysis and study shall include all power distribution systems, beginning at the CPS Energy vault service transformer to the secondary buses of each switchgear, panelboard as described hereafter. Contractor to furnish short-circuit and protective device coordination studies as prepared by equipment manufacturer. By using the equipment manufacturer, the study allows coordination of proper breakers, fuses, and current transformers. The coordination study shall begin with the utility company feeder protective device and include all the electrical protective devices down to and include the largest feeder circuit breaker and power distribution panelboards. The study shall also include variable frequency drives, harmonic filters, power factor correction equipment, transformers and protective devices associated with variable frequency drives, emergency and standby generators associated paralleling equipment and distribution switchgear.

The study shall be prepared by the equipment manufacturer and certified with the registration seal and signature of a Registered Professional Engineer. The Engineer shall be an employee of the electrical switchgear manufacturer. The Engineer shall be qualified by experience in the preparation of studies having similar requirements and magnitude to those specified in this Section of the Specification. c. The initial copy of the Fault and Coordination Study and Selective Coordination Study shall be submitted with the electrical switchgear submittals prior to the purchase of any equipment so that the required interrupting current ratings, duties, and overcurrent protective devices (OCPDs) types, can be substantiated. Any modification to the electrical equipment, equipment bus bracing, overcurrent protective device types, etc. that are required by the recommendations of the short circuit and coordination study shall be provided by the switchgear manufacturer prior to manufacturing any electrical equipment. d. The Short Circuit Analysis shall terminate at each branch bus at the lowest utilization voltage secondary bus where the symmetrical short circuit RMS amperes is less than 10,000 amperes (10,000 amperes total source plus all motor contribution). It is the intent of these specifications to determine all locations in the entire electrical system where the symmetrical short circuit amperes meets or exceeds 10,000 amperes at either 208 or 480 volts. The short circuit analysis shall compare interrupting ratings of all electrical protective devices connected to each bus with that of the available fault current at the load terminals of each protective device.
