Electrical Safety UK, Ltd.

Proud Partner of Electrical Safety UK, Ltd. Rotherham (Sheffield), England

For nearly two decades, I have been closely associated with the UK’s—and Europe’s—foremost authority on arc flash and electrical safety: Electrical Safety UK (ESUK). Based in Rotherham (Sheffield), England, ESUK has been at the forefront of advancing electrical safety practices for over twenty years. I have had the privilege of contributing to this journey from its early days and continue to serve on the company’s board. My association with ESUK began close to its inception, when its founder, Mr. Mike

NFPA 70E 2 second arc duration

IEEE 1584, NFPA 70E and the “2-Second Arc Duration” Myth

IEEE 1584, NFPA 70E and the “2-Second Arc Duration” Myth Question:I’ve heard that an arc flash can’t last longer than two seconds. Is that true? Short answer:No! An arc flash can absolutely last longer than two seconds. Neither IEEE 1584 nor NFPA 70E says an arc flash is physically limited to two seconds. The two-second value is an assumption used for exposure time, not a limit on how long an arc can actually exist. This misunderstanding comes from a statement

Arc-Flash Boundary and NFPA 70E — Is It a “Safe” Place to Stand?

Question: Arc Flash Boundary – Safe? Since NFPA 70E does not require arc-flash PPE outside of the arc-flash boundary, does that mean it’s a safe place to stand? The Short Answer: No Way! (I have the advantage of seeing many staged arc flash events in the lab.) What NFPA 70E Actually Says About the Arc-Flash Boundary Let’s start with the basics. NFPA 70E requires that an arc-flash boundary (AFB) be determined and as part of an arc-flash risk assessment (see
