Arc flash hazard analysis performed to IEEE 1584-2018, covering equipment from 15 kV switchgear down to 120/208 V panelboards.

The study answers a question your people ask every time they open a door: how much energy is released if this faults while I am standing here, and what do I have to be wearing. AC and DC systems are both covered. Equipment below 240 V fed from a source with less than 2000 A bolted fault current uses default values rather than a calculated result, and the report says so rather than presenting a default as a calculation.

Scope

  • Incident energy calculations
  • Arc flash boundary determination
  • PPE category assignment
  • Equipment labeling
  • Recommendations to reduce incident energy
