In the quiet corner of a bustling engineering firm, Marcus was staring at a cable design that just wouldn't work. The project—a high-voltage substation—required cables that could survive a massive fault without melting into a puddle of copper and plastic He knew the standard he needed: , the definitive guide for calculating thermally permissible short-circuit currents The Hunt for Information
