Instructor: Jim Phillips, P.E.

Jim is not just another trainer reading a script. For almost 40 years, Jim has been helping tens of thousands of people around the world understand electrical power system design, analysis and safety. Having taught over 2500 classes during his career to people from all seven continents (Yes Antarctica is included!), he has developed a reputation for being one of the best trainers and public speakers in the electric power industry.

When asked questions about some topics,  Jim’s explanations often run along the line of “Well, here’s what we were thinking and a bit of history” or “Here is why it was written in a particular way.”

His unique insider’s perspective is based on:

  • Four Decades in the Industry
  • Vice Chair: IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations.
  • International Chair: IEC TC78 Live Working – 40 + Standards and Documents
  • Technical Committee Member: NFPA 70E Standard for Electrical Safety in the Workplace
  • Steering Committee: IEEE/NFPA Arc Flash Research Collaboration
  • Author: “How Guide to Perform Arc Flash Hazard Calculations”
  • Contributing Editor: NECA’s multi-award-winning Electrical Contractor Magazine
  • Member: ASTM F18 Committee.

This class is divided by subject into 43 separate modules.  After completing the modules and passing a final quiz – 70%, a continuing education certificate can be printed and stored in your personal library for future use.
