Surge Protection for Laser Cutting Machine per NFPA 79 (2024) NFPA 79 Industrial Machinery (2024) The latest release of NEC/NFPA 70 edition 2023 (NEC 2023) has placed a greater emphasis on increasing personnel safety by mandating the use of Surge Protective Devices (SPDs). From 2014 to 2023, the number articles now requiring SPDs has increased significantly for applications ranging from Modular Data Centers, Fire Pumps, Elevators, Critical Power Systems, Dwellings (Dormitories, Homes, Hospitals, Hotels), etc. Laser Cutting Machine Threat to industrial machines Various codes and standards possess safety interlock criteria including the American National Standards Institute (ANSI) standards and NFPA 79 for Industrial Machinery. However, until now, these standards have only just begun to address the expanding role that surge protection plays preserving the integrity of equipment and, more importantly, protecting the lives of personnel. A study commissioned by the Fire Protection Research Foundation, “Data Assessment for Electrical Surge Protective Devices”, provides results of a survey of facility managers concerning surge damage. (NFPA 2014) The study shows that 26 percent of facility managers had damage to safety interlocking systems on industrial machines due to surges . The main purpose of these safety interlocking systems is to protect workers and maintenance personnel from contact with exposed live parts and electric shock. Failure of these devices can put personnel at an increased risk of injury. CNC laser Cutting Machine The solution for NFPA 70 and NFPA 79 To make the installation of a Surge Protective Device (SPD) at the industrial machines interlocking safety circuit mandatory which in turn increases the equipments reliability. NFPA 70 Article 670.6 Overvoltage Protection. "Industrial machinery with safety circuits shall have overvoltage protection.” In addition, the future NFPA 79 is considering the following changes: 7.8.1 Surge Protective Devices (SPDs). "SPDs shall be provided for industrial machinery with safety interlock circuits to protect against the effects of overvoltages due to lightning or switching surges.” as well as 4.5.2 Electromagnetic Compatibility (EMC). "Transient suppression, isolation, or other appropriate means shall be provided where the equipment of an industrial machine generates electrical noise or transients, which can affect the operation of equipment that is on or part of the industrial machine." CNC Laser Cutting Drill Selecting an SPD for Laser Cutting Machine NEC/NFPA 70 require that Surge Protective Devices (SPDs) shall be UL1449 Listed . This means selecting a surge protector is easier than it has ever been. There are only a few choices available for SPDs that are UL Listed for any of the most commonly used surge standards including UL1449 5th Edition, UL497B, and UL497E.
