Abstract
Arc flash hazard calculations used to predict the magnitude of the heat hazard are based on tests with open-tip vertical electrodes in enclosures. Arc ratings for PPE are developed using opposing electrodes. Tests with electrode configurations that forced the arc plasma jets outward from the box yielded significantly higher heat energy measurements. When placed within this directional plasma flow, protective flame resistant (FR) fabrics yielded significantly lower arc ratings.
