WebIf the available fault current exceeds the SCCR of the equipment, it presents a severe arc flash hazard and potential destruction of electrical components. ‍ Lesson: The higher the short-circuit current that is allowed to pass through, the more severe the arc flash. ‍ Time. Time is another major factor in arc flash severity. WebOther related articles were likewise changed. Inadequate SCCR could lead to a potentially hazardous arc flash condition for a short circuit downstream of the panel. While changing designs to get higher SCCR ratings, designers have also sought ways to minimize arc flash risks for workers who interact with the control panels.
