Wire marker cards are stiff, flat cards that hold rows of self-adhesive labels used to identify wires and cables. These labels can be solid numbers (0-9), letters (A-Z), or pre-printed with common electrical symbols and words.
The purpose of wire markers is to create a clear, legible, and standardized labeling system for electrical panels and control systems. This is critical for fast installation, efficient troubleshooting, and safe maintenance. For comprehensive solutions, see our wire marker books.
Solid marker cards contain all the same character (e.g., a full card of 7s). Consecutive marker cards are pre-printed with numbers in a sequence (e.g., 1, 2, 3... or 01-50), allowing for faster labeling of sequential items. We offer a variety of all solid wire marker cards.
NEMA/ANSI markers are wire labels that are pre-printed with colors and/or text to comply with NEMA or ANSI electrical code standards. This helps ensure that a panel is labeled in a compliant and universally understood way. We can assist with custom tags for specific compliance needs.
These labels are made from industrial-grade, flexible vinyl or cloth. They have an aggressive adhesive and a top-coat that resists oil, solvents, water, and abrasion, ensuring the legend remains readable for the life of the panel. For extra protection, explore our self-laminating labels and superior mark clear label protectors.
