Why Arc Flash Analysis Training Matters
An arc flash label is only as good as the study behind it. Small errors in field data, electrode configuration, enclosure size or clearing time can understate the hazard by a wide margin, and every one of those errors ends up on a label in front of a worker. Engineers who understand the IEEE 1584-2018 method can do three things software alone can't: validate the results, defend the assumptions, and recommend changes that actually reduce incident energy.
This course should be taken with our Power System Fundamentals Course - November 6, 2026
This course is also a companion to our Short Circuit Analysis/Study And Protective Device Coordination Course - November 12-13, 2026
Arc Flash Analysis Training Overview
The course assumes the short circuit and coordination studies are already complete. It opens by setting out the inputs the arc flash study needs from them.
Day One covers:
- the regulatory framework: OSHA, NFPA 70E-2027, CSA Z462:24
- study scope and deliverables under IEEE 1584.1
- field data collection and modelling
- the IEEE 1584-2018 method: range of applicability, electrode configurations, arcing current variation and enclosure size correction
- a hand-calculation workshop on a 480 V panel
Day Two covers:
- arc duration and operating scenarios
- medium-voltage calculations and special cases
- DC arc flash for battery, UPS and PV systems
- labels, PPE and documentation
- engineering mitigation, from energy-reducing maintenance switching to arc-resistant equipment
It closes with how to review a study and catch common software errors.
This course doesn't teach energized work practices. Electricians and supervisors should take our NFPA 70E or CSA Z462 courses.
Learning Outcomes
Upon completing this course, participants will be able to:
- Define the scope and deliverables of an arc flash study using IEEE 1584.1.
- Identify the short circuit and coordination study inputs an arc flash study needs.
- Plan field data collection, including enclosure dimensions, gaps and working distances.
- Apply the IEEE 1584-2018 range of applicability and electrode configurations.
- Calculate arcing current, arc duration, incident energy and arc flash boundary by hand for LV and MV equipment.
- Evaluate minimum and maximum operating scenarios and reduced arcing current.
- Apply recognized DC arc flash methods to battery, UPS and PV systems.
- Produce labels and documentation that meet NFPA 70E-2027 and CSA Z462:24.
- Recommend and evaluate engineering controls that reduce incident energy.
- Review arc flash study results and identify common modelling errors.
