3M SDR-L3 Wire Marker Tape

Product Description

The 3M SDR-L3 is a wire marker tape designed for identifying and labeling electrical wiring in residential and commercial installations. Wire marker tapes provide a durable, readable identification method directly on conductors, cables, and wire bundles, helping technicians trace circuits, verify connections, and meet labeling requirements during installation and service. The SDR-L3 is suited for use by electricians and other trade professionals who need a reliable, legible marking solution in panel, conduit, and junction box applications.

Wire marker tape of this type is commonly used in residential and light commercial electrical work, including panel wiring, branch circuit identification, low-voltage control wiring, and instrumentation applications. It is appropriate wherever clear wire identification is required by code or best practice, including new construction, renovation, and service work on existing systems.

Key Features

• Tape-format wire marker for direct application to conductors and wire bundles
• Suitable for circuit identification in panels, conduit runs, and junction boxes
• Supports code-compliant labeling practices for electrical installations
• Designed for use by licensed electricians and low-voltage technicians

Compatibility

Designed as a general-purpose wire marker tape suitable for standard electrical and low-voltage wiring applications typical in residential and commercial installations.

Installation Notes

Wire marker tape is applied by electricians during rough-in, trim-out, or service work. Always de-energize circuits and follow OSHA lockout/tagout procedures before working inside panels or junction boxes. Apply markers to clean, dry wire surfaces for best adhesion and legibility. Labeling practices should conform to applicable NEC requirements for circuit identification.
