The automaker 3 10 initiated a proactive program to enhance worker safety when working on electrical equipment. The program not only included the fuse change out, 2 10 but also a short circuit current study, arc flash hazard analysis, affixing safety labels to equipment, and providing safety training and personal protective 2x10 equipment (PPE) to workers, as needed. By using 2 3 4 5 10 10 10 10 Amp 10 Cooper Bussmann current-limiting fuses in potential Prospective Short-Circuit Current symmetrical RMS arc-flash situations the amount of electrical energy * 200-225A fuses are derated to 900V released is considerably less, thereby helping to reduce the risk of potential injury.
