behind those reverse tables should dial down the incident energy in good align- ment and if it doesn’t, the product is not sound. Secondarily, if your system has operational problems and you’re losing money or safety confidence because of it, then you need more than a localized coor- dination where arc flash is high. In reality, you might need several software studies for your plant, including site-wide protec- tive device coordination, harmonics, short circuit, load flow, voltage drop, and/or load shedding studies. But for the arc flash haz- ard, your diagnosis likely requires labeling via either method and electrical worker arc flash hazard training and proper PPE.
