Arc flash incidents represent one of the most severe and unpredictable electrical hazards in industrial environments. When an arc fault occurs, the electrical discharge between conductors or to ground can reach temperatures exceeding 35,000°F (19,400°C)—hotter than the surface of the sun. This intense thermal event releases a blast of energy that includes molten metal, pressure waves,... https://www.otherarticles.com/business/industrial/419320-how-arc-flash-kits-are-engineered-for-maximum-thermal-and-electrical-protection.html
