Arc Flash Study Toolkit

An arc flash is the sudden release of energy from a fault that ionizes the air between conductors. It produces incident energy measured in calories per square centimeter, a pressure wave, molten metal, and a temperature high enough to vaporize copper. Arc flash analysis (per IEEE 1584-2018) calculates how much incident energy a worker would receive at a working distance, and from that derives the arc flash boundary — the distance from the equipment within which an unprotected worker could receive a second-degree burn.

The toolkit on this page is a screening calculator. It estimates the cost-benefit of commissioning a full arc flash study for your facility based on size, voltage class, age, and worker exposure. It is not an IEEE 1584 calculation — for that you need a one-line, short-circuit data, and protective device coordination, all run through software like SKM, ETAP, or EasyPower. ClarkTE produces those PE-stamped studies, the equipment labels they generate, and the NFPA 70E training your workforce needs to use them.
