Thomas & Betts WDT-5020 Conduit and Voltage Marker Cards - Vinyl

The WDT-5020 carries the legend "460 VOLTS" in black printing on a safety orange background, with 7/8 inch character height. It is a voltage marker for conduit and equipment identification, so if you need a different voltage callout you need a different legend number in the same card series.

Each card holds 4 markers. Cards are sold in multiples of 25, which is also the inner package quantity, so the smallest practical buy is 25 cards, or 100 individual markers. A full outer carton runs 600.

Nothing extra. The markers are self-sticking vinyl, so you peel and apply directly to clean conduit, panel, or enclosure surfaces. No banding, clips, or separate adhesive required.

The WDT-5020 marker cards are stated as OSHA compliant, and the black-on-safety-orange color scheme with 7/8 inch characters is what makes them readable at a distance during service work. They are also RoHS compliant, which matters if your facility procurement requires it.

Stick-on vinyl markers like the WDT-5020 are the fast option for identifying voltage on existing runs, especially where you are labeling long stretches of raceway or retrofitting an unmarked system. They apply without drilling or fasteners. Engraved phenolic nameplates are the better call where the label has to survive abrasion, chemical washdown, or outdoor UV for years, or where a spec drawing calls for permanent mechanical attachment.

Count the points you want marked, then divide by 4, since each card yields 4 markers. Round up to the nearest 25 because cards ship in multiples of 25. For example, 300 marked points needs 75 cards. Note that 460 VOLTS is a single legend, so any other voltages in the building need their own legend cards ordered alongside.

The manufacturer part number is WDT-5020, from Thomas & Betts. Within this marker card family the number is what identifies the legend, so quoting WDT-5020 is what gets you 460 VOLTS rather than another voltage.
