3M 7000031520 Wire Marker Tape Refill Roll Letter E

Product Description

The 3M 7000031520 is a printed wire marker tape refill roll designed for clear, durable wire and cable identification in electrical installations. Each roll is pre-printed with the letter E, providing a consistent and legible label for circuit conductors, terminal connections, and control wiring. Sold in a box of 10 rolls, this refill format keeps marker dispensers loaded and ready for continuous use on the job. Electricians and panel technicians rely on this type of marker tape to meet labeling requirements and maintain organized, code-compliant wiring layouts.

This wire marker tape refill is suited for commercial and industrial electrical work where consistent conductor identification is required. Typical applications include panel terminations, switchgear wiring, control cabinets, and motor control centers. The pre-printed E designation is commonly used to mark equipment grounding conductors or other circuit points designated with that letter in the wiring schedule. Installations requiring NEC-compliant circuit identification benefit from standardized marker tape like this roll format.

Installation Notes

Wire marker tape is applied by qualified electricians during termination and labeling stages of electrical installation or maintenance. De-energize all circuits before working at terminals or inside panels where markers are being applied. Ensure the marker surface is clean and dry before application to achieve proper adhesion and label longevity. Follow applicable NEC requirements for conductor identification when selecting and placing wire markers.
