Arc Flash Safety Standards

ETAP arc flash study software complies with the latest analysis of arc flash safety standards and calculation methods:

  • IEEE 1584-2018 - “Guide for Performing Arc-Flash Hazard Calculations”
  • IEEE 1584.1 2013 - “Guide for the Specification of Scope and Deliverable Requirements for an Arc-Flash Hazard Calculation Study in Accordance with IEEE Std 1584”
  • IEEE 1584b 2011 - “IEEE Guide for Performing Arc-Flash Hazard Calculations Amendment 2: Changes to Clause 4”
  • IEEE 1584a 2004 - Amendment to the “Guide for Performing Arc-Flash Hazard Calculations”
  • IEEE 1584 2002 - “Guide for Performing Arc-Flash Hazard Calculations”
  • DGUV-I 203-077 (formerly BGI/GUV-I 5188E)
  • NFPA 70E 2012 to 2021
  • NFPA 70E 2009 – “Standard for Electrical Safety in the Workplace”
  • National Electric Code (NEC) 110.16 (Arc Flash Safety Label requirement)
  • National Electric Safety Code® (NESC®). NESC sets the ground rules for practical safeguarding of personnel during installation, operation or maintenance of electric supply.
  • CSA Z462 2018 (Canadian Arc Flash Analysis standard)
  • OSHA 29 CFR 1910
  • ASTM D 120-14a

Compliance with Safety Guidelines

  • Limit the arc flash incident energy based on protective device maximum fault clearing time (e.g., two seconds)
  • Built-in empirical equation range limit alerts & system grounding configurations
  • Automatically distinguish between load & line side protective devices
  • User-definable & typical equipment gap between conductors, enclosure dimensions, & working distances (based on IEEE 1584)
  • Automatically handle arc flash incident energy calculation for LV are sustainability (i.e. 240V, Ibf < 2kA) automatic assignment
  • Automatically assign arc flash hazard category for LV are sustainability (i.e. 240V, Ibf < 2kA) automatic assignment
  • Simulate main protective device isolation in the arc flash analysis by using user-defined tools
  • Determine are flash boundary based on different incident energy limits (i.e. EB energy values)
  • The arc flash analysis software include standard-defined insulating gloves for printing on the on the arc flash safety labels.
  • The arc flash analysis program can be configured to include the maximum and minimum arc fault currents to obtain the worst case results.
  • Additional Fault locations for every faulted bus:
    • Source PD
    • Bus Arc Faults
    • Load PD Arc Faults
    • Load PD Load Side Arc Faults (back enclosures)
