3M 7000031525 Wire Marker Tape Refill Roll Letter J

Product Description

The 3M 7000031525 is a printed wire marker tape refill roll pre-printed with the letter J, designed for consistent, legible wire and cable identification in electrical installations. Each roll provides a ready supply of J-marked labels that adhere directly to wire insulation, keeping conductors organized and traceable throughout a panel, raceway, or conduit run. Licensed electricians and panel wiring technicians use these rolls with compatible 3M wire marker dispensers to maintain code-compliant labeling during new construction, retrofit, and maintenance work.

These refill rolls are suited for commercial and residential electrical applications where individual conductor identification is required. Typical uses include circuit panel labeling, terminal block wiring, and any installation where NEC-compliant wire marking is necessary. The rolls are sold in a box of 10, providing a practical supply quantity for ongoing jobsite or shop use.

Installation Notes

Wire marker tape is applied by qualified electricians during wiring installation or panel termination work. De-energize all circuits before working inside any panel or enclosure.
