Short Circuit Analysis Report

A short circuit study determines the short circuit currents available at various points in the system. This information is necessary to evaluate the equipment being utilized in the system, to set the protective devices and to ensure that its ratings comply with the NEC 110.9, Interrupting Rating, and 110.10, Circuit Impedance and Other Characteristics. The available short circuit fault current is the key component in calculating incident energy and arc flash boundary. Hence, the calculated short circuit currents and a protective device evaluation should be included in the short circuit section of the arc flash hazard calculation study report. Read more at
