Safer Power for Auto Manufacturing

Safer Power for Auto Manufacturing



A global auto manufacturer was expanding its USA manufacturing plant to begin building a new model. One of the goals of the expansion was to design a state-of-the-art power system—one that provided redundant power and maximized safety for the plant’s personnel.

The most dangerous activity at the plant is the annual power system maintenance, which includes opening and closing circuit breakers and other tests. To keep the plant operational, personnel perform these tasks on energized circuits, which presents a potential arc-flash safety hazard. The danger is heightened because this task is only performed once a year, and less familiar tasks pose an increased risk of human error.

Customer Profile

  • Customer: Global Auto Manufacturer
  • Location: Southeast USA
  • Industry: Manufacturing
  • Application: Arc-Flash Mitigation


The SEL solution significantly improved safety by reducing the arc-flash hazard risk at the new facility. The solution also allows engineers to perform maintenance remotely, which helps them to work at a safe distance from any potential arc-flash events.

According to the facilities engineer on the project, the SEL protection scheme provides reliable power and helps protect their personnel and equipment. As a result, the manufacturer recently completed retrofitting the original plant’s power system with the same SEL equipment.
