How to design electrical systems to reduce arc flash incident energy

Existing arc flash codes and standards like IEEE 1584 and 1584.1 present models that electrical engineers can use to estimate incident energy levels in power distribution equipment, but they provide limited direction regarding how equipment construction should be considered in the calculations. The NFPA 70E hierarchy of risk control describes that the most effective ways are designing/specifying to remove the hazard at its source, minimize the severity of hazard and blocking the hazard from affecting employees.
