Arc flash is a dangerous condition caused by an arcing fault, which is the flow of current through the air between phase conductors, or between phase conductors and neutral or ground. This arcing fault can result in extremely high temperatures, a tremendous pressure blast, and shrapnel hurling at high velocity. Quantifying and mitigating this danger is a safety priority for many data center managers who look to protect their equipment, and most importantly, their employees.
