The 2-second arc duration is often misunderstood in IEEE 1584 and NFPA 70E applications. This article explains what the assumption really means and when engineering judgment must be applied.
The arc-flash boundary in NFPA 70E is often misunderstood as a “safe” distance. This article explains what the boundary actually represents and why below 1.2 cal/cm² does not mean risk-free.
IEEE 1584.2 was recently published! The full title is: IEEE Guide and Checklists for Data Collection for Performing an Arc-Flash Hazard Calculation Study in Accordance with IEEE Std 1584™ and IEEE Std 1584.1™ for Systems Operating at Three-Phase 50/60 Hz AC 1000 V and Below This newest addition to the IEEE 1584 family complements the existing standards: IEEE 1584 – 2018: IEEE Guide for Performing Arc-Flash Hazard Calculations IEEE 1584.1 – 2022: IEEE Guide for the Specification of Scope and
Electrical safety isn’t theory—it’s protection for people, equipment, and uptime. For more than 40 years, Jim Phillips has helped engineers, electricians, and safety professionals turn the NFPA 70E Standard for Electrical Safety in the Workplace into practical, actionable safeguards that reduce incidents and strengthen compliance. At Brainfiller, Jim leads some of the industry’s most trusted NFPA 70E training programs, known for converting complex standards into proven, field-ready procedures. What Is NFPA 70E and Why It Matters Developed by the National
No, the title doesn’t have a typo — “Standards” is plural for a reason. Over 20 years ago, in 2002, the original IEEE 1584 standard was released and changed the game for arc flash safety around the world. Since then,…
NFPA 70E 205.4 and Noncontact Diagnostics If you’re in the electrical world, you’ve probably seen how fast technology is changing the way we maintain equipment. The 2024 edition of NFPA 70E is no exception—it reinforces the importance of keeping electrical…
Success – seven simple letters make up this impactful word. These days, it feels like every electrical safety post on social media is focused on dramatic arc flash accidents – the more intense the imagery, the more engagement it gets.
Artificial Intelligence is no Substitute for Knowledge! The Risks of Misinformation in Electrical Safety: The Role of AI and Online Resources Artificial Intelligence (AI) has emerged as a transformative force in the technology sector, with capabilities ranging from content generation…
NFPA 70E 110.3(J) Incident Investigations Electrical power systems, like all complex systems, are prone to failures. These failures can arise from a wide range of causes, including improper work procedures, faulty or inadequately maintained equipment, or human error, among others.
2026 NEC and Dates on Arc Flash Labels – Update Although the 2026 Edition of the National Electrical Code (NEC) is still a work in progress as of writing this article, it appears the issue of placing a date on…
