calorie per square centimeter
Energy per areaexact by definition
One thermochemical calorie per square centimetre, equal to 41,840 J/m² exactly. It is the unit of arc-flash incident energy, and the unit every rating of arc-rated protective clothing is written in.
Watch out: This unit sizes a hazard; it does not make work safe. An arc-flash incident energy is only as good as the available fault current and the protective device's clearing time at the arcing current, both of which come from a study of the actual installation. A figure computed from assumed inputs is not a basis for selecting protective equipment.
