Equipment labels, not wall signs

These are adhesive equipment labels sized to fit on a panel door, a disconnect, a wireway or a junction box cover. They are not large rigid wall signs. If you need a big door mounted sign for an electrical room, contact us and we will quote it separately.

The 6" x 4" landscape footprint fits the flat area on most NEMA 1 and NEMA 3R enclosures without wrapping over a hinge or a latch, which is where cheap stickers usually start peeling.

Where electrical hazard labeling is required

NEC 110.16 requires arc flash warning field marking on equipment likely to require examination while energized. NEC 110.21 and 408.4 cover identification of the equipment and its circuits. OSHA 1910.303(e) requires markings that are durable enough for the environment they are installed in, which is exactly why a laminated industrial vinyl label outlasts an office printer sticker.

For equipment specific incident energy data, use the arc flash label designer instead of a premade label so the calculated values print on the label itself.

Frequently asked questions

What is the difference between an electrical hazard label and an arc flash label?

An electrical hazard label is a general warning that energized parts are present. An arc flash label carries equipment specific data such as incident energy, working distance, arc flash boundary and required PPE, and is required by NEC 110.16 on equipment likely to be examined while energized.

Will these labels hold up outdoors?

Yes. They are printed on industrial vinyl with a UV stable overlaminate and a permanent acrylic adhesive, rated for outdoor service in roughly -40F to 180F.

Can I get my company name or custom wording on the label?

Yes. Use the custom DANGER or WARNING label option and type up to three lines of your own text under the fixed ANSI header.

What size are the labels?

The standard printed vinyl label is 6" x 4" landscape. Engraved products such as nameplates and panel tags are produced up to 4" wide.
