How this was calculated
Matched the selected equipment to an abbreviated NFPA 70E 2021 screening row. Voltage, fault current (30 kA), and clearing time (6 cycles) identify study inputs but do not replace the table's complete conditions.
Important: Informational screening only. A licensed professional's IEEE 1584 arc-flash study determines actual incident energy, approach boundaries, and PPE. Verify with your copy of NFPA 70E.
