Arc Flash NFPA 70 E

A Live Seminar on Introduction and Review of Arc Flash NFPA 70 E

Credit: 7.5 PDH’s (1-Day); 0.75 CEU’s

Lead Instructor: Professor Bobby Rauf, PE, CEM, MBA

Course Description

This course caters to Professional Engineers, Non-Licensed Engineers, Technicians, Facilities Managers, and other professionals who are interested in enhancing their understanding of arc flash risk in their operations or those of their clients. This course is intended to serve as an introduction, review and update on 2018 NFPA 70E based Arc Flash Standards and Requirements. The course begins with an introduction to the general arc flash phenomenon. The science behind the arc flash phenomenon is covered, coupled with discussion of potential causes for arc flash and properties of an electrical power distribution system. Insofar as the relationship between an arc flash event and the electrical power distribution system is concerned, pertinent components such as fuses and breakers, and their role in initiation and mitigation of an arc are explained. Value of arc flash risk analysis is covered, and recommended approach in the absence of a formal arc flash study is explained. PPE prescribed for the four (4) arc flash hazard classes, 1, 2, 3 and 4, is discussed. The three (3) approach boundaries are discussed and illustrated. Arc Flash terminology and respective definitions are reviewed. Arc Flash labelling requirements and methodology are explained. This course is designed to serve as a tool for staying abreast of arc flash requirements with highlights of revisions adopted in 2018. As such, this course can be used to satisfy the Professional Development Hour requirements set forth by most US State Boards and other licensure agencies; or simply, to meet periodic employee training requirements.


  • Skills and knowledge of Arc Flash phenomenon.
  • Better comprehension of the difference between Shock Hazard and Arc Flash Hazard.
  • Awareness and skills needed to identify the three (3) boundaries of potential Arc Flash situations.
  • Knowledge needed for identification and use of appropriate Arc Flash PPE.
  • Understanding the importance of Arc Flash Incident Energy Analysis and what they entail.
  • Options and alternatives when arc flash risk analyses are not immediately feasible.
  • Get introduced to the “category method” for assessing the PPE requirements
  • Why “doing nothing” and hoping an arc flash incident will not occur “on your watch” is not an option.
  • Get introduced to arc flash PPE, and associated “do’s and don’ts.”
  • Importance of arc flash training for your employees
  • The importance of arc flash risk analysis based labels.
  • What to do when potential arc flash incident energy exceeds the highest classification.
  • Participants will learn about the NFPA 70 E changes adopted in 2018.

Why you shouldn’t miss this seminar – How this seminar can benefit you and your organization; what is unique about this course:

  1. By attending this seminar, you don’t just earn PDH’s, CEH’s, or CEU’s, you leave the seminar with valuable knowledge and awareness of hazards of arc flash, how to prevent them and how protect against them.
  2. If you are responsible for ensuring safe operation (switching) of electrical equipment or power distribution systems in your operations or facilities, or those of your clients’, and you feel inadequately prepared as far as arc flash risk is concerned; or perhaps you don’t know where to begin, then, this seminar is a must for you.
  3. If you are responsible for ensuring safe implementation of work on energized electrical equipment, or simple opening of electrical cabinets, electrical enclosures, electrical switchgear, breaker panels, etc. – and you lack adequate arc flash knowledge – then, you mustn’t miss this seminar.
  4. In this seminar, you will get an opportunity to attain basic to intermediate level knowledge on the “somewhat” abstract subject of Arc Flash and the NFPA 70 E Code through the developer and presenter of this seminar, Mr. S. Bobby Rauf. Mr. Rauf, over the years, has simplified and presented complex topics like Electrical Engineering, Mechanical Engineering, Thermodynamics, Fluid Statics & Dynamics through seminars, courses, training and text books.
  5. If your knowledge about arc flash and NFPA 70 E is dated, then this seminar will update you on notable revisions adopted into the NFPA 70 E standard in 2018.
  6. Some seminars and courses end up being monotonous monologues from the presenter to the audience. Not this one. In this seminar, you will get an opportunity to air questions, share your success stories – as well as, frustrations – in the arc flash arena.
  7. Through this seminar, engineers and other professionals who are not practicing electrical engineers have, in the past, taken away knowledge and awareness about arc flash that is commensurate with their existing science and engineering aptitude.

Who should attend:

  • Licensed PE’s, Professional Engineers, and other professionals, who need to meet the license or certification renewal PDH (Professional Development Hour), CEH (Continuing Education Hours), or CEU (Continuing Education Unit) requirements.
  • Facility/Plant Managers, Plant Engineers, Engineering Managers, Energy Professionals, Project Managers, and Manufacturing Engineers who feel a need to learn about arc flash and the NFPA 70 E requirements in order to make informed decisions related to electrical work, switching and operation of electrical switchgear.
  • Technicians or electricians responsible for performing energized work and switching of electrical power distribution equipment.
  • Construction managers who manage electrical power equipment installations.
  • Other professionals whose annual PLP, Performance and Learning Program, include electrical courses, training, or seminars.
