Transformer Labels | Transformer Warning Labels

Frequently Asked Questions

Q. Where can I buy transformer warning labels for electrical transformers and switchgear?

We carry transformer warning labels and signs in Danger and Warning formats for electrical transformers, substations, switchgear enclosures, and pad-mount transformers. Labels are available in adhesive polyester and vinyl for direct application to transformer housings, as well as aluminum signs for mounting on fencing and enclosures surrounding high-voltage transformer equipment.

Q. What information should a transformer warning label include?

A transformer warning label should include the signal word (Danger or Warning), a high voltage warning, a no unauthorized entry message, and in many cases, the voltage rating and electrical shock hazard symbol. We offer transformer labels with all of these required elements in OSHA and ANSI-compliant formats, as well as customizable templates for adding specific voltage ratings or contact information.

Q. Are transformer labels required by OSHA or the NEC for electrical equipment?

Yes. OSHA 1910.303 requires that electrical equipment be marked to warn of electrical hazards, and the National Electrical Code (NEC) requires transformer identification labels including voltage, KVA rating, and manufacturer information. We carry both safety warning labels and informational transformer identification labels to help facilities meet all applicable electrical marking requirements.

Q. Can transformer labels be customized with voltage rating and KVA information?

Yes. Our customizable transformer label templates allow you to specify the voltage rating, KVA capacity, serial number, installation date, and any other required identification information. Custom transformer labels are available in adhesive polyester and vinyl formats that bond securely to transformer housings and withstand the heat, moisture, and UV exposure of outdoor transformer installations.

Q. Are reflective transformer warning signs available for outdoor pad-mount transformers?

Yes. We offer reflective aluminum transformer warning signs for outdoor pad-mount transformers, substations, and utility enclosures. Reflective signs remain visible at night under flashlights or vehicle headlights, helping prevent accidental contact with energized transformer equipment after dark. Pre-drilled holes make installation on transformer pad fencing and equipment housings quick and straightforward.

About our Transformer Labels

Our line of transformer warning labels is designed to help keep public away and safe.
Transformer accidents are deadly and all too common. When a vandal breaks into a transformer either maliciously ignorant of the danger or deliberately to steal the copper and other increasingly valuable metals, a potential disaster is exposed.

• Labels are laminated for maximum durability. Reflective labels are ideal for visibility at night.
• Mr. Ouch labels are licensed from NEMA. See NEMA No 260, “Safety Labels for Pad Mounted Switchgear and Transformers Sited in Public Areas”.
