Installation Notes

Wire markers are applied by electricians and low-voltage technicians during conductor termination or labeling phases of an installation. De-energize circuits before applying markers to conductors in live panels, in accordance with NFPA 70 lockout-tagout procedures. Ensure the wire surface is clean and dry before applying adhesive-backed markers to promote proper adhesion. Write-on markers should be filled out with a permanent marking pen before application.
