Estimate of Arcing Current and Flash-Protection Boundary

The IEEE 1584 calculation method has empirical equations for conversion of calculated bolted (zero impedance) faults to estimated arcing fault currents. Due to the resistance of the arc, arcing current will be less than a zero impedance fault at the same location. The lower the system voltage, the greater impact the arc resistance has on the calculated arcing current. 

Flash-Protection Boundary

The flash-protection boundary is the distance at which a person without personal protective equipment (PPE) may get a second degree burn that is curable. This is the same as the Arc Flash Boundary discussed in NFPA 70E.
