Answer Capsule: A compliant arc flash label template has seven zones: signal word header, equipment ID, system voltage, arc flash boundary, incident energy at a working distance or a PPE category, shock approach boundaries, and the assessment date. NFPA 70E-2024 130.5(H) and NEC 110.16 require voltage, boundary, one PPE method and the date. Never show incident energy and PPE category together.
Your engineer handed you a 90-page arc flash study. Now you need labels on 40 pieces of gear by Friday, and nobody gave you a layout. That is the gap this arc flash label template fills. Get the layout wrong and the inspector flags it, even if every number in the study is right.
Print Pro AZ prints arc flash labels for contractors across the country, and the same layout questions come up on almost every order. Where does the date go? Do you list the PPE category or the incident energy? Brent Hanke, founder of Print Pro AZ, built the Arc Flash Label Field Guide to answer those questions once.
This post walks through every zone of the template and shows a filled-in arc flash label example with real numbers. Use the download form on this page to get the printable field guide, which includes the full-size template.
What Does a Compliant Arc Flash Label Template Include?
A compliant arc flash label template includes the four data items required by code, plus three layout zones that make the label usable in the field. The code items come from NFPA 70E-2024 Section 130.5(H) and NEC 2026 Section 110.16.
| Zone | What goes there | Where the rule comes from |
|---|---|---|
| 1. Header | Signal word (WARNING or DANGER) and "Arc Flash and Shock Hazard" | ANSI Z535.4 and the owner's safety program |
| 2. Equipment ID | The name on the one-line diagram, such as MSB-1 | Best practice, ties the label to the study |
| 3. Nominal system voltage | 480 VAC, 208 VAC, and so on | NEC 110.16 and NFPA 70E 130.5(H) |
| 4. Arc flash boundary | Distance in feet and inches | NEC 110.16 and NFPA 70E 130.5(H) |
| 5. PPE method | Incident energy with working distance, OR the PPE category | NEC 110.16, NFPA 70E 130.5(G) and 130.5(H) |
| 6. Shock boundaries | Limited and restricted approach distances | NFPA 70E Table 130.4(E)(a) for AC, (b) for DC |
| 7. Assessment date | The date the study was completed, plus the study reference | NEC 110.16 and the NFPA 70E 130.5(H) review cycle |
Zones 3, 4, 5 and 7 carry the required data. Zones 1, 2 and 6 are not spelled out in NEC 110.16, but they make the label usable. The Print Pro AZ guide to NFPA 70E 2024 arc flash label requirements covers the code text in depth. This post stays on layout.
How Is the Arc Flash Label Template Laid Out, Zone by Zone?
The template runs top to bottom in the order a worker reads it: the hazard first, the equipment second, the numbers third, and the date last.
Zone 1: Signal Word Header
Print the signal word in the largest type on the label. NFPA 70E does not set a voltage or cal/cm2 cutoff for DANGER versus WARNING, and WARNING is the common choice. Under ANSI Z535.4, DANGER is reserved for hazards that will result in death or serious injury if not avoided. Many owners switch to DANGER above 40 cal/cm2, but that is a program choice, not a code rule. Use an orange band for WARNING and a red band for DANGER.
Zone 2: Equipment ID
Print the equipment name exactly as it appears in the study table. If the study says MSB-1, the label says MSB-1. An inspector matches the label to the study, and a mismatch reads as a mislabeled panel. On multi-section switchgear, print one label per section, each with its own ID.
Zone 3: Nominal System Voltage
Print the nominal voltage and system type, such as 480 VAC or 208Y/120 VAC. This is the first of the four required items under NEC 110.16 and NFPA 70E 130.5(H). Use the value from the study, not a meter reading.
Zone 4: Arc Flash Boundary
Print the arc flash boundary as a distance in feet and inches. This is the distance where incident energy drops to 1.2 cal/cm2, the onset of a second-degree burn. The study calculates it for each piece of equipment. Never copy it from a similar panel. Print it as "4 ft 6 in," not "4.5 ft."
Zone 5: Incident Energy OR PPE Category
Print one PPE method, never both. NFPA 70E-2024 130.5(G) lets your engineer choose the incident energy analysis method or the arc flash PPE category method for each piece of equipment. Section 130.5(H) then requires the label to show the result of the method used.
- Incident energy method: print the energy and the working distance together, such as "8.7 cal/cm2 at 18 in."
- PPE category method: print the category, such as "Arc Flash PPE Category 2."
A label that shows both is one of the five inspection failures in the field guide. If your study table has both columns filled for one row, ask the engineer which method applies.
Zone 6: Shock Approach Boundaries
Print the limited approach boundary and the restricted approach boundary. These come from NFPA 70E-2024 Table 130.4(E)(a) for AC and Table 130.4(E)(b) for DC. They depend on voltage, not on the arc flash calculation. Print them under a "Shock Hazard" subheading.
Zone 7: Assessment Date and Study Reference
Print the date the arc flash risk assessment was completed. NEC 2026 110.16 requires the assessment date, not the date you applied the label. Add the study reference, such as the engineering firm and report number. NFPA 70E 130.5(H) requires a review of the supporting data at intervals not to exceed 5 years, and this date starts that clock.
Field rule: If your engineer signed the report on 08/12/2026 and you install the labels in November, the label still says 08/12/2026.

What Does a Filled-In Arc Flash Label Example Look Like?
A filled-in arc flash label example for a 480 V main switchboard reads as the table below. These are the sample values used throughout the Print Pro AZ field guide.
| Zone | Printed text |
|---|---|
| Header | WARNING. Arc Flash and Shock Hazard. Appropriate PPE Required. |
| Equipment ID | MSB-1 |
| Nominal system voltage | 480 VAC |
| Arc flash boundary | 4 ft 6 in |
| Incident energy | 8.7 cal/cm2 at 18 in working distance |
| Limited approach boundary | 3 ft 6 in |
| Restricted approach boundary | 1 ft 0 in |
| Assessment completed | 08/12/2026 |
Read it the way a worker would. The header names the hazard and MSB-1 names the gear. The arc flash boundary tells you where to stand without arc-rated PPE, and the incident energy tells you what arc rating you need past that line. The date tells you whether the study is still current.
Notice what is not there. No PPE category, because this label uses the incident energy method. No install date. No generic "ARC FLASH HAZARD" text on its own, which does not satisfy NEC 2026 110.16 once your state adopts that edition. Confirm which edition your AHJ enforces.
Should You Print the Arc Flash Label Template Yourself or Order It?
You can print the template on an office printer for a temporary marker, but a permanent label needs a material that survives the environment. The NEC requires field-applied hazard markings to be durable for where they are installed, and an unreadable label fails the same way a missing one does. The Print Pro AZ post on arc flash label materials and UL 969 covers material selection.
- Printable arc flash label from the field guide: fine for a mockup, a training handout, or a placeholder while permanent labels ship. Paper and laser labels fade, peel and smear in a mechanical room.
- Custom printed labels: Print Pro AZ prints on UV-rated polyester for indoor gear and .048 aluminum for outdoor and harsh locations. Send your study as a PDF, Excel or CSV file and the label set ships the same week.

Frequently Asked Questions
What information is required on an arc flash label?
NEC 2026 110.16 requires four items: nominal system voltage, arc flash boundary, either incident energy with working distance or the arc flash PPE category, and the date the assessment was completed. NFPA 70E-2024 130.5(H) requires the same core data. Equipment ID and shock boundaries are optional but appear on most labels.
What size should an arc flash label be?
Neither NEC 110.16 nor NFPA 70E sets a label size. The label has to be visible before the cover is opened, so the signal word should be legible from a few feet away. The standard Print Pro AZ arc flash label is 3.5 by 5 inches.
What date goes on an arc flash label?
The date the arc flash risk assessment was completed, not the date the label was printed or applied. NFPA 70E 130.5(H) requires the supporting data to be reviewed at intervals not to exceed 5 years. The assessment date on the label is what an inspector uses to check that.
Conclusion
A compliant arc flash label template has seven zones, and four carry the data NEC 2026 110.16 and NFPA 70E-2024 130.5(H) require: voltage, arc flash boundary, one PPE method, and the assessment date. Never print incident energy and PPE category on the same label. The date is the study date, not the install date.
