Five simple words “at each point of work” were added to step 7 of the Process for Establishing and Verifying an Electrically Safe Work Condition.  Step 7 is testing absence

No Short Circuit Data Available? Try an Iterative Approach. The available short circuit data (fault current) from the electric utility or other source is a very important variable when conducting

Why Does Electric Utility Fault Current Change/ The available fault current from an electric utility can change over time creating unique challenges for power system studies such as short circuit

QUESTION: Would opening or closing a circuit breaker be considered normal operation?  What about resetting a tripped circuit breaker?  This short explanation is from the Q&A Session during my 2024

“NFPA 70E requires retraining at intervals not to exceed 3 years“ Retraining in safety-related work practices and applicable changes to NFPA 70E shall be performed at intervals not to exceed 3

This video provides a short overview of the 6 PDH/ 0.6 CEU On-Demand Training Program: Coordination Studies by Jim Phillips, P.E. A coordination study, sometimes known as protective device coordination

Achieving perfect coordination may seem as elusive as spotting a unicorn. In order to obtain perfect coordination, overcurrent devices are selected and set so that only the device nearest a

NFPA 70E states that retraining in safety-related work practices and applicable changes in this standard shall be performed at intervals not to exceed 3 years. This time frame is so

What do you do if the short circuit data is unavailable from the electric utility company? Can you use an “infinite source” calculation? Many say an infinite source is not

Why Horizontal Electrode Configuration? Although not the most common electrode configuration that is used when performing an arc flash study, using the Horizontal Conductors/Electrodes inside a metal box/enclosure (HCB) produces

This video is a preview of the 16 hour class: How to Perform an Arc Flash Study – IEEE 1584.  In the full class, Jim Phillips, P.E. takes you through

Jim Phillips continues his discussion of the major changes to the 2021 Edition of NFPA 70E. In Part 2 he covers changes and a major reorganization to Article 110 General

The most important element of electrical safety is eliminate the hazard and risk. In Part 3 of this 5 part series about the 2021 Edition of NFPA 70E, Jim Phillips

Jim Phillips wraps up the discussion of the 2021 Edition of NFPA 70E with Part 5 of 5: Informative Annex D Incident Energy and Arc Flash Boundary Calculation Methods, Annex

Below is a sample of the Live Streaming of my class about Arc Flash Studies and the 2018 Edition of IEEE 1584.  It includes a brief discussion of calculations, an

Jim Phillips explains the upcoming live streaming of his classes. How to Perform an Arc Flash Hazard Calculation Study – 2018 IEEE 1584 Live Streaming with Q&A in 4 Sessions:

This is the first of a three part series where Jim Phillips talks about alternative arc flash labeling strategies to simplify the process.  He points out that some labels can

Jim Phillips discusses the new exception added to the 2018 Edition of NFPA 70E. 130.5(H) Exception No. 2 provides an alternative method for arc flash labeling of complex systems that

Jim Phillips describes his method for simplifying arc flash labeling and possibly eliminate the need to re-label when there are system changes. Use a standardized arc flash boundary and the

Jim Phillips answers people’s questions that are sent during an on line program about arc flash studies. Questions include: What to do for a circuit breaker between a generator and
