Webb8 mars 2024 · Arc flash events create serious risks in nearly all industrial operations. The proper use of appropriately sized and applied low- and medium-voltage motor control centers (MCCs) can reduce the likelihood of arc flash events, but the risk still exists. Fortunately, MCCs can be enhanced to further reduce risks to both people and equipment. Webbworker and (9) grounding scheme. 100A LPS-RK_SP fuses were the smallest fuses tested. Data for the fuses smaller than that is based upon the 100A data. Arc-flash values for actual 30 and 60A fuses would be considerably less than 100A fuses, however, it does not matter since the values for the 100A fuses are already so low.
