Issue #22 - 2015 NFPA 70E

New year 2015 edition of NFPA 70E, Standard for Electrical Safety in the Workplace, was released in September 2014 and supersedes all previous editions. The 2015 edition is the tenth time NFPA 70E has been published since it was introduced in 1979. Several terms used throughout NFPA 70E have been changed for the 2015 edition. ARCAD's arc flash calculation software program has been updated in order to conform to the new standard. The most important changes and new program features are listed below:

  1. Nominal system voltage for shock hazard assessment has been revised reflecting changes to NFPA 70E table 130.4(c)(a)
  2. All references to the prohibited approach boundary have been deleted throughout the standard and the AFA V5.0 program. Once the restricted approach boundary was crossed, there were no other requirements in the NFPA 70E 2015 edition.
  3. All label layouts and terminology have been rearranged to meet the new standard requirements.
  4. Personal protective equipment (PPE) recommendations displayed on labels created using the program can be reviewed, edited or reset to default values. The feature will let you making necessarily PPE adjustments required for various tasks in English and a variety of international languages. Also, the PPE requirements in new NFPA 70E standard have changed from previous editions of the standard. They may become different again and the feature will let you reflect the changes as the safety standard evolves.
  5. The program is now memorizing selected label style (including label size, text color, style), optional extra line title, value etc.

  • Detailed arc flash analysis using the IEEE 1584 equations and the Lee method.
  • Ensure compliance with NEC, OSHA, NFPA 70E 2015, IEEE P1584 and CSA Z462 standards and regulations.
  • Instantly determine arcing current, incident energy, arc flash, limited, restricted and prohibited shock approach boundaries, hazard level, typical clothing system.
  • Add fuse and circuit breaker data including time-current characteristics for the devices that are not already featured in the built-in protection device library.
  • Perform arc flash boundary calculations based on 1.2 cal/cm^2 (5 Joules/cm^2) onset energy to second degree burn for bare skin exposure per IEEE 1584 Guide and other incident energy levels as well, such as the rating of proposed personal protective equipment, or evaluated onset to second degree burn energy.
  • Create warning labels in English and a variety of international languages.
  • Preview, save, print arc flash labels in high resolution graphic format.
  • Save input configuration, protection device information.
  • Perform analysis using metric, imperial units.
  • Save reports including equipment data, calculation results, warning label.
