Engraved arc flash labels
Arc flash data engraved into phenolic instead of printed on vinyl. Voltage, arc flash boundary, incident energy or PPE category, approach boundaries and study date, taken straight from your engineering study.

Add any design to your cart as it is, or open it in the sign builder to change the wording, size or colours.
We engrave the study, we do not do the study
The numbers on an arc flash label come from an arc flash study done by an engineer. Send us the study output or a spreadsheet and we engrave each label to match, one per piece of equipment. Prefer to fill in values on site? We also cut labels with blank fields. Read arc flash labels in Canada for what normally goes on one.
Why engraved in the electrical room
Electrical rooms get hot and dusty, and labels get handled. Vinyl labels can curl, fade and lift at the edges. An engraved phenolic label has no print layer and can be screwed or riveted to the enclosure. When the study is updated, you swap the plate.

FAQ
Arc Flash Labels: common questions
What information goes on an arc flash label?
Typically the nominal voltage, arc flash boundary, incident energy at a working distance or the PPE category, the limited and restricted approach boundaries, the equipment ID and the date of the study. Your study and CSA Z462 practice set the exact content.
Do you calculate the arc flash values?
No. The values come from an engineering arc flash study. We engrave what the study gives you.
Can you make arc flash labels with blank fields?
Yes. We can engrave the header and field names and leave lines blank for values to be written in with a paint marker.
