Arc Flash Mitigation in LV Systems

A common misconception within the electrical industry is that low-voltage systems (typically operating at 600V or lower) pose a lesser arc flash risk than their higher voltage counterparts. While the potential incident energy may be lower in some cases, underestimating the hazards present in low-voltage systems can have devastating consequences. This article aims to debunk this misconception and outline strategies for effectively managing arc flash hazards within low-voltage environments.
