3M 7000031527 Wire Marker Tape Refill Roll Letter L

Product Description

The 3M 7000031527 is a printed wire marker tape refill roll used to label and identify electrical wiring in control panels, junction boxes, and distribution systems. Each roll is pre-printed with the letter L, providing a consistent, legible identification mark for phase conductors, load terminals, or any circuit wire designated by that character. This product is sold in a box of 10 rolls, making it practical for stocking on service vehicles or in shop inventory. Electricians and panel builders use these markers to meet labeling requirements and simplify future troubleshooting.

These wire marker refill rolls are suited for residential, commercial, and light industrial electrical work wherever conductor identification is required. Common applications include motor control panels, terminal strip wiring, switchgear assemblies, and low-voltage control circuits. The pre-printed format eliminates the need for hand-marking, reducing errors and speeding up production wiring tasks.

Installation Notes

Wire marker tape is applied by qualified electricians during panel assembly, termination, or circuit labeling work. De-energize circuits and follow NFPA 70 (NEC) safe work practices before accessing live panels or terminal strips. Ensure wire surfaces are clean and dry before applying markers so adhesion is not compromised. Store unused rolls in a dry environment to maintain label integrity.
