The 2026 National Electrical Code (NEC) brings some of the most impactful changes in recent history — especially for electrical safety and compliance. Among the most significant 2026 NEC updates are the new, mandatory arc flash labeling requirements, which now apply to nearly all commercial and industrial electrical equipment. If your team is preparing for NEC 2026 changes, understanding these new requirements is critical to keeping your facility compliant, passing inspectio

When working with three-phase (3ø) electrical equipment, there’s always the risk of a short circuit or other malfunctions that could cause a sudden release of energy through the air.

In any facility with energized electrical equipment, arc flash labels are more than just stickers—they are life-saving tools. Yet, it’s not uncommon to find missing, damaged, or outdated arc flash labels in commercial and industrial settings. This oversight doesn’t just jeopardize compliance; it puts workers directly in harm’s way. At Herzig Engineering, we help companies avoid these hidden dangers through comprehensive arc flash studies and on-site label application services
