Arc flash study
NEC 110.16 and CFR 29 require Electrical panels, Motor Control Centers, Switchboards, Industrial Control Panels, and other electrical equipment to be equipped with Arc Flash warning labels. The Arc Flash label is to warn personnel of the potential Arc Flash hazard and to indicate the PPE required to examine, inspect or adjust electrical equipment.
An Arc Flash study calculates the Incident energy that can be released by an Arc Flash. It also helps determine the minimum require Personnel Protective Equipment (PPE) needed.
The Arc Flash study complements the results of a Coordination and short circuit studies. It incorporates the equipment settings selected in the Coordination study and the short circuit values calculated by the short circuit study. Both of studies results are used to calculate the incident energy relased by an Arc Flash.
The Arc Flash study generates results that are included in the Arc Flash labels to indicate the PPE requirement and the Arc Boundary. It also helps to satisfy the Arc Flash PPE requirements listed in NFPA 70E.
As part of the process to calculate the Incident energies released by an Arc Flash, the equipment settings selected in the coordination study may need to be change. In many occasions, it is possible to change the equipment settings established in the coordination study. The equipment setting changes can lower the incident energy release in an Arc Flash. By changing the equipment settings, the coordination engineer can lower the PPE requirements, increase safety and maintaining optimal operation for the facilities or plants.
The Coordination and Arc Flash studies are complementary to each other. The coordination study establishes initial equipment settings. As the Arc Flash study is performed, the initial equipment settings can be reviewed and adjusted to manage the Arc Flash by changing the equipment settings. Both of these studies have a direct effect on one another. It is always recommended that both studies be performed simultaneously to provide best and fastest results.
