3M 7000031530 Wire Marker Tape Refill Roll Letter O

Product Description

The 3M 7000031530 is a printed wire marker tape refill roll designed for cable and wire identification in electrical installations. Each roll is pre-printed with the letter O, providing a clear, consistent label for conductors, terminals, and wire bundles. This refill format is intended for use with compatible 3M wire marker dispensers and is sold in a box of 10 rolls, making it practical for shops and service vehicles that go through markers at volume. Electricians and low-voltage technicians rely on wire markers like these to keep panels, conduit runs, and junction boxes organized and code-traceable.

Wire marker tape refills are used across residential, commercial, and industrial electrical work wherever conductor identification is required. Common applications include panel labeling, switchgear wiring, data and communication cabling, and any installation where circuit traceability needs to be maintained over time. The pre-printed format eliminates handwriting inconsistency and speeds up the labeling process on busy job sites.

Installation Notes

Wire marker tape is applied by qualified electricians or low-voltage technicians during or after wire pulling and termination. De-energize circuits before working near terminals where markers are being applied. Ensure the marker surface is clean and dry before application for proper adhesion. Follow applicable NEC requirements for conductor identification and labeling in the jurisdiction where work is performed.
