Arc Flash NFPA 70 E 2018:

  • The instructor S. Bobby Rauf was very knowledgeable of the topic; he brought in many interesting actual experiences into the presentation; was engaging with the students and kept it interesting for the 8 hour period. John P., PE, 2019
  • Instructor was very knowledgeable of the topic and was able to answer everyone’s questions. David B. P.E.
  • The course was prepared well and the instructor did an excellent job both on presenting the material and interacting with the class. Richard R. P.E
  • First, I appreciate that you did not cancel the class despite extremely limited enrolment! I needed this to get ‘across the finish line’ for my ‘live’ credits.Second, there were some terrific aspects of Bobby’s course.  In addition to the comprehensive slide deck which is a reference book in itself, his use of the NFPA 70E-2018 handbook to discuss the code sections, with the explanation from experts, along with his experience and then working examples, made this course extremely informative and interesting.  There was no loss of interest in this course throughout the day!  As an instructor myself, I can appreciate the difficulty of trying to administer an 8-hour course via webinar!  There was adequate time for interaction and discussion of the particular questions that came up with respect to the code, the interpretation, and implementation. Lastly, a number of case studies throughout the day added particular relevance to the Arc Flash reality. I look forward to future sessions with SEM Train! John S., PE 2019

  • Bobby seems very knowledgeable and passionate about what he is presenting. He is very good at using real-life experiences to illustrate or clarify how some of these concepts can be implemented.
  • The discussions about management maxims, performance indicators, scheduling, and communication were very helpful. Also, useful, were the sections on professionalism and positive reinforcement, and project start-up/closeout.(The seminar provided) a better understanding of the project screening and vetting process as well as project performance metrics.
  • The course was exactly what I was looking for and was well presented.
