Arc flash labeling wrapper
Why you care (60 seconds)
Arc flash labels warn workers about hazards at equipment. Missing labels can trigger inspection findings and safety risks.
Where people lose time
- Forgetting to label service equipment and panels.
- Using generic labels that do not meet requirements.
- Misplacing labels where they are not visible.
This is
The rule in plain language
Electrical equipment likely to require examination, adjustment, or servicing while energized must have arc flash warning labels.
When it applies
Service equipment, switchboards, panelboards, and similar gear.
What you must do (checklist)
- Identify equipment requiring arc flash labels.
- Apply warning labels that meet code requirements.
- Place labels where they are visible before opening equipment.
Quick examples
- Service equipment typically requires arc flash labeling.
- Labels must be durable and clearly visible.
This is not
Common misreads
- Assuming a nameplate is enough to meet labeling requirements.
- Using outdated or unreadable labels.
What it doesn't cover
- Detailed arc flash analysis methods.
- NFPA 70E labeling requirements beyond NEC.
False friends
- A safety sticker is not the same as a required arc flash warning label.
Exceptions & edge cases
- Some equipment may not require labels if not likely to be serviced energized.
- Existing installations may have different expectations based on AHJ.
