His Arc Flash Training Courses have become the industry standard. Arc-flash boundary is defined as the boundary inside which a worker may be exposed to incident energy of more than 5 Joules/cm 2 (1.2 cal/cm 2). All of this provides him with a very unique perspective from the insider’s view. NFPA 70E sets out a number of boundaries from the live electrical conductors, arc flash boundary and shock protection. ![]() Jim is also the Head of the United States delegation for the IEC Technical Committee 78 – Live Working. Arc flash hazard warning labels will be designed as per NFPA 70e standards and include the information of arc flash category or incident energy value, flash protection boundary or arc flash boundary limits along with the other approach boundary details. Integrating the Results into the Electrical Safety Program Chapter 18. The Arc-Flash Hazard Calculation Study Report Chapter 17. Jim is Secretary of IEEE 1584 – IEEE Guide for Arc Flash Hazard Calculations and is the Liaison to Geneva, Switzerland based International Electro-Technical Commission’s (IEC) TC78/WG-15 – Arc Flash Protection, as well as a member of many other codes and standards committees. Our expert services include arc flash energy calculation as per IEEE 1584 standards. Once an arc flash risk assessment has been conducted, in which the arc flash boundary, the incident energy at the working distance and the personal protective equipment required has been determined, Article 130.5 (C) in the 2015 edition of NFPA 70E further dictates that the label must contain these important elements: 1. Arc-Rated Clothing and Personal Protective Equipment. ![]() Although not yet part of any standard, this is the first book of it’s kind to include DC arc flash calculations and worksheets with many examples and illustrations based on a few well known technical papers. ![]() You will also see how to successfully make assumptions and simplify the overall process. Jim provides many tricks that can be used for the study and also warnings about the potential traps that could be encountered. Many questions and potential problem areas are frequently encountered when performing the Arc Flash Study.
