Understanding the 2020 NEC Code Change (NYC) — Arc Flash Labeling & the 2026 Deadline
The 2020 National Electrical Code (NEC), adopted by New York City, requires commercial and industrial facilities to ensure
their electrical equipment displays accurate, current arc flash labels. With a 2026 compliance deadline, thousands of NYC
facilities will need to verify labeling, update studies, and document ongoing changes.
What’s Required?
Arc flash labels must be up-to-date and reflect current system conditions. Labels are not a “set it and forget it” item—any system
change can impact the data shown on the label.
Arc Flash Labels must include:
- Incident energy (cal/cm²)
- Arc flash boundary (inches/feet)
- Available fault current
- Recommended PPE and glove class
- Working distance
- Nominal voltage
- Limited, restricted, and prohibited approach boundaries
Updates Required
Labels must be updated after any system modification or following a new arc flash study. That includes equipment changes,
upstream utility changes, added loads, transformer work, switchgear changes, and more.
Applies To (No Exceptions)
The requirement applies to panels, switchgear, MCCs, transformers, and other major electrical equipment.
Why This Matters for NYC Facilities
- Safety: Protects personnel from arc flash hazards and supports safer maintenance practices.
- Compliance: Reduces exposure to fines, citations, and liability tied to non-compliance.
- Operational Continuity: Lowers the risk of incidents that can cause downtime, disruptions, or insurance complications.
Step-by-Step Compliance Breakdown
1) Audit Existing Labels
- Check for missing, outdated, damaged, or illegible labels.
- Compare labels against recent system upgrades or changes.
2) Commission an Arc Flash Study
- Hire a qualified provider (for example, a NETA-certified team) to analyze the system.
- Collect field data and confirm/produce accurate single-line diagrams.
3) Install New Labels
- Apply labels to all applicable equipment.
- Use durable materials and place labels where they are clearly visible.
4) Document & Digitize
- Keep digital records of arc flash studies, label sets, and update history.
- Use a tracking system so future electrical changes trigger label/study review.
5) Train Your Team
- Review label information and PPE requirements with maintenance staff and contractors.
- Run safety briefings and periodic refreshers, especially before major shutdowns or upgrades.
6) Schedule Regular Reviews
- Integrate study updates into your preventive maintenance plan.
- Set reminders for periodic audits so labels don’t quietly drift out of compliance.
