The minimum required interrupting capacity rating of circuit breakers and fuses in the IDS equipment circuits are determined by calculation and summarized in the IDS Short Circuit Analysis (Reference 9) and the IDS Protection Coordination Study (Reference 10). These calculations utilize the worst case short circuit contribution from each battery, battery charger, and motor load of the IDS, which determines the minimum required protective device interrupting capacity in accordance with the criteria stated in the IEEE Standard 946, Sections 7.1 and 7.9 (Reference 1), IEEE Standard 741(Reference 2), and IEEE Standard 242(Reference 3).

The nameplate capacity ratings of the as-built IDS circuit breakers and fuses in the IDS equipment circuits are inspected in accordance with the Construction Quality Verification Program (Reference 4). The nameplate rating for each of these circuit breakers and fuses is evaluated to assure the device interrupting capacity exceeds the minimum required interrupting capacity rating.
