In a bold move towards revolutionizing power transmission safety and efficiency, a group of industry giants has joined forces to champion the global adoption of fault-managed power (FMP) systems. The recent unveiling of fault-managed power technology, classified as Class 4 under the 2023 National Electrical Code (NEC), marks a significant milestone in enhancing power delivery mechanisms.
VoltServer, the pioneering company behind the innovative FMP system, has taken a proactive step by establishing a non-profit organization in partnership with prominent electrical cable providers such as Belden, Cisco Systems, Panduit, and Prysmian. This collaborative effort, known as the Fault-Managed Power Alliance, aims to leverage expertise from key industry players to accelerate the integration of NEC Class 4 standards.
FMP systems, designed to transmit power through cables from a transmitter to a receiver, boast advanced fault monitoring capabilities that automatically deactivate energized circuits in the event of potential hazards like short circuits, ground faults, or overcurrent conditions. These safety parameters have been intricately woven into the updated NEC guidelines and UL Solutions standards, ensuring a secure operational environment.
One of the primary advantages of FMP technology is its ability to deliver higher power capacities over extended distances compared to traditional power delivery methods. With a voltage limit of 450 V for fault conditions, FMP systems can safely transfer hundreds of watts per pair of conductors over significant distances, catering to a wide array of applications ranging from industrial manufacturing to wireless networks and indoor farming.
The collaborative efforts of industry leaders underscore the significance of standardizing FMP systems, a journey that began in 2020 with the formation of a group by UL to address power delivery technologies beyond the realms of existing classifications. The issuance of UL 1400‐1 and UL 1400‐2 standards in 2022, alongside the incorporation of a new power classification under Article 726 in the 2023 NEC edition, reflects a collective commitment to advancing power transmission methodologies.
While the adoption of FMP systems may still be in its nascent stages, with only a handful of states having completed the 2023 NEC update process, industry organizations are actively developing training resources to facilitate seamless integration and interoperability. The deployment of Class 4 power in various sectors, including power distribution infrastructure, LED lighting, and smart buildings, underscores the transformative potential of fault-managed power technology.
As the Fault-Managed Power Alliance continues to drive innovation and collaboration in the realm of power transmission, industry frontrunners like VoltServer, Belden, and Panduit are spearheading groundbreaking projects that exemplify the capabilities and benefits of FMP systems. With a shared vision to propel the adoption of FMP technology, these industry leaders are poised to shape the future landscape of power delivery infrastructure on a global scale.
