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 Frain, CEng FIET MCMI, recognized a critical and largely unmet need: greater awareness, understanding, and practical solutions for arc flash hazards—not only in the UK, but across Europe. Together, Mike and I co-authored several pioneering articles and technical papers that helped raise—and in many cases introduce—awareness of arc flash risks and the importance of improved electrical safety practices throughout the UK and Europe, often in the face of skepticism toward this emerging discipline.
Today, those early efforts have fully come to fruition. What began as a small seed of innovation and education has grown into a robust and influential organization—a proverbial oak in the field of electrical safety—with ESUK firmly leading the way.
Under the leadership of Managing Director Ms. Rebecca Broadhead, CMgr MCMI, who has been integral to the company’s development since its early years, Electrical Safety UK has experienced significant growth and diversification. Rebecca’s strategic vision, commitment to excellence, and customer-focused approach have transformed ESUK into a dynamic organization delivering high-quality, practical solutions.
Her leadership has strengthened internal systems while driving the expansion of ESUK’s safety management services and industry-focused training programs.
Today, ESUK provides a comprehensive suite of services designed to help organizations manage electrical risk and enhance workplace safety, including:
From bespoke training solutions to industry-leading electrical safety consultancy, Electrical Safety UK supports blue-chip organizations and businesses of all sizes throughout Europe—helping them reduce risk, improve compliance, and protect both lives and operations.
We are proud to be associated with Electrical Safety UK, Ltd., and to share in their mission to make electrical work safer, smarter, and more effective across every sector they serve.
Brainfiller offers several courses designed and taught by Jim, all targeted to engineers, electricians, and safety professionals.
NFPA 70E Qualified Worker Training (8 hours)
Comply with the qualified electrical worker training and refresher training requirements from NFPA 70E.
How to Perform an Arc-Flash Study | IEEE 1584 (16 hours)
Modeling, arcing current, incident energy, arc-flash boundaries, and system-level mitigation.
Fundamentals of Electrical Safety (2 hours)
Shock hazards, arc-flash basics, and the building blocks behind NFPA 70E.
DC Electrical Safety Fundamentals (2 hours)
Key safety practices for data centers and DC systems.
All training is available live, on-site, or on-demand, and includes completion certificates with CEU/PDH documentation.
Because Jim is embedded in NFPA, IEEE, IEC, and NEC committees, he sees emerging trends before they appear in the standards.
His training materials are updated immediately after each standards cycle, keeping teams aligned with NFPA 70E, IEEE 1584, and OSHA expectations.
🔧 From code to craft: Jim explains why requirements exist and how to apply them correctly in real electrical systems.
