Electrical Labels Made To Order

Two materials, one standard: permanent

Engraved 2-ply acrylic is the workhorse for panel and equipment identification. The legend is cut through a cap layer to expose a contrasting core, so there is no printed surface to peel or wear off. It is UL-approved Rowmark DurMark, non-conductive, UL94-HB flame rated under Yellowcard E354751, and available in seven standard color combinations.

Industrial adhesive vinyl covers our premade safety and hazard labels: 3.0 mil stock with a UV-stable overlaminate, rated 5+ years outdoors, for surfaces where a rigid plate is not practical.

Electrical label FAQ

What electrical labels does the NEC require?

The most commonly cited rules are NEC 110.16 (arc flash warning), 110.21(B) (field-applied hazard marking durability), 110.24 (available fault current), 408.4 (circuit directory and source of supply), and 705.10 for interconnected power sources. NFPA 70E adds incident energy or PPE category labeling on equipment likely to be worked on energized.

Do electrical labels have to be engraved?

NEC 110.21(B)(3) requires field-applied markings to be permanent and suitable for the environment. Engraved 2-ply acrylic satisfies that plainly: the legend is cut into the material, so there is no printed surface to peel or wear off. Printed adhesive labels are allowed when they meet the durability requirement, which is why we use 3.0 mil industrial vinyl rated for 5+ years outdoors for our premade safety labels.

What material are your electrical labels made from?

Engraved labels are cut from Rowmark DurMark, a UL-approved rigid 1/16" 2-ply acrylic with UL Yellowcard E354751 and a UL94-HB flame rating. It is non-conductive and UV stable. Premade adhesive safety labels are printed on 3.0 mil industrial vinyl with a UV-stable overlaminate.

Can I put my own wording on electrical labels?

Yes. Every engraved label is made to order with your exact text, size, line count, and color. Build it in the custom label designer and see live pricing before ordering.

What colors are used for electrical labels?

ANSI Z535 uses white on red for DANGER, black on orange for WARNING and black on yellow for CAUTION. Our engraved acrylic comes in orange with white text, and our printed vinyl WARNING labels are black on orange. We also stock black/white, green/white, blue/white, and white/black for equipment identification and circuit ID.
