Calculate arc flash energy

WebThe following sets out how a competent electrical engineer can use the calculator to arrive at an incident energy level at a stated working distance as well as an arc flash boundary which is the distance at which the incident energy level equals 1.2 cal/cm 2 (or the threshold of a second-degree burn). WebAn arc flash boundary is the distance from the equipment in question to the point where the energy that would be present in an arc flash is 1.2 cal/cm2. This is the level at which it will cause only second-degree burns rather …
