From this Article:
As of April 26, 2006, suppliers of UL listed Industrial Control Panels (ICP) must clearly label the Short Circuit Current Rating (SCCR) of each panel so that users can properly apply them per National... (View Full Article)
(Electrical Distribution and Protection)
From this Article:
Current-limiting fuses can limit arc flash incident energy to low values provided that the arcing fault current exceeds the fuse's threshold current. Threshold current is defined as the lowest... (View Full Article)
