14/2 CL3P CMP Plenum Wire – 1000FT White Stranded Copper

Description

14/2 CL3P CMP Plenum Wire – Professional 1000FT Unshielded Bare Copper for Fire-Safe Installations

14/2 CL3P CMP plenum wire is the trusted choice for low-voltage professionals wiring commercial buildings, data centers, and residential plenum spaces. This 1000FT white pull box delivers 14AWG stranded bare copper conductors, a CL3P/CMP dual-rated unshielded jacket, and the flexibility to route cleanly through drop ceilings and tight building cavities.

Furthermore, this cable meets the fire safety requirements established under NEC Article 800 for CMP-rated Communications Multipurpose Plenum cable (nofollow). As a result, it is fully approved for installation in air-handling ceiling spaces, HVAC return-air ducts, and any other plenum environment where reduced smoke and flame spread are mandated by code. Consequently, electricians, integrators, and contractors can specify this wire with complete confidence on inspected job sites.

Key Features of Our 14/2 CL3P CMP Plenum Wire

• 14AWG Stranded Bare Copper Conductors: This 14/2 CL3P CMP plenum wire uses genuine stranded bare copper — not copper-clad aluminum. Stranded copper provides outstanding flexibility for bending around framing members and routing through conduit. Moreover, bare copper delivers superior conductivity and long-term reliability compared to CCA alternatives that corrode in humid ceiling environments.
• CL3P and CMP Dual-Rated Jacket: The jacket carries both CL3P (Class 3 Plenum) and CMP (Communications Multipurpose Plenum) certifications. This dual rating, verified under UL 13 for plenum cable construction and materials (nofollow), satisfies the broadest range of plenum-space code requirements across all US jurisdictions. In other words, a single spool covers every inspector and every AHJ.
• Unshielded Design for Maximum Flexibility: The unshielded construction keeps the cable diameter slim and the bend radius tight. As a result, this wire routes easily through crowded ceiling cavities, junction boxes, and conduit without the stiffness associated with shielded variants. Additionally, the absence of shielding reduces termination time per run.
• Low-Smoke Flame-Retardant White Jacket: The white outer jacket is engineered to resist flame spread and minimize toxic smoke output in fire conditions. Furthermore, the white color provides a clean, professional appearance in finished ceiling spaces and simplifies color-coded wiring systems for easy circuit identification during maintenance.
• 1000FT Pull Box Packaging: Each 1000FT roll provides enough wire for multiple full-floor low-voltage runs without mid-run splices. Additionally, the pull box format allows tangle-free payout on active job sites, reducing installation time and minimizing waste on large-scale commercial projects.
• Wide Application Compatibility: This wire is suitable for audio and speaker circuits, intercom systems, security alarm wiring, paging systems, and power-limited control circuits. Consequently, it serves as a highly versatile stock item for low-voltage contractors who manage multiple system types in a single building.
• Commercial Building and Data Center Ready: The combination of CL3P/CMP ratings, stranded bare copper, and 14AWG sizing makes this cable appropriate for data centers, office buildings, retail environments, hotels, and educational facilities. Therefore, procurement teams can source a single SKU for all plenum low-voltage runs across a diverse project portfolio.
• ETL Verified and RoHS Compliant: This wire is ETL verified and fully RoHS compliant, meeting all US safety and environmental documentation requirements. Therefore, it passes inspection requirements on government, institutional, and commercial job sites where certification documentation is mandatory.

Why Choose This 14/2 CL3P CMP Plenum Wire for Your Project?

When it comes to plenum-space wiring, the jacket rating is not optional — it is a life-safety requirement. This 14/2 CL3P CMP plenum wire carries both the CL3P and CMP ratings, which means it satisfies NEC Article 725 for power-limited Class 3 circuits and NEC Article 800 for communications wiring simultaneously. In contrast, standard CL2 or CL3 cable is prohibited in plenum spaces and must be removed at the contractor’s cost if discovered during inspection. Moreover, installing non-plenum cable in air-handling spaces creates a documented fire liability that no commercial client should accept. Browse our full Speaker and Security Cable collection (DoFollow) for the complete range of CMP-rated gauges and configurations.

The 14AWG stranded bare copper conductors in this 14/2 CL3P CMP plenum wire represent the ideal balance of gauge and flexibility for mid-length audio and low-voltage runs. At 14AWG, this cable supports speaker runs up to approximately 80 feet at 8 ohms before resistance losses become audible in a high-fidelity context. Furthermore, it handles intercom, paging, and access control circuit lengths common in commercial building core-and-shell wiring with minimal voltage drop. As a result, 14AWG is the most-specified gauge for distributed audio in conference rooms, offices, and retail spaces where run lengths fall between 40 and 80 feet. Additionally, for high-power speaker runs or distances beyond 80 feet, consider our 12/2 CL3P CMP Plenum Speaker Wire (DoFollow) for the extra current capacity that 12AWG provides.

The 1000FT roll format is a direct economic advantage on large projects. This 14/2 CL3P CMP plenum wire allows a single spool to service an entire floor of a commercial building without splicing interruptions. In other words, the 1000FT format cuts labor time, reduces connection points that could introduce resistance or failure, and lowers the per-foot installed cost compared to shorter spools. Consequently, project managers and procurement teams consistently favor 1000FT bulk rolls for phase-one rough-in wiring. For intercom and security applications where shielding against interference is required, also explore our 18/2 CL3P CMP Plenum Rated Shielded Cable (DoFollow) as a complementary SKU for the same plenum environments.

Frequently Asked Questions

Q: What is the difference between CL3P and CMP ratings, and does this wire have both?

Yes — this 14/2 CL3P CMP plenum wire carries both the CL3P and CMP ratings on a single jacket. CL3P stands for Class 3 Plenum and is defined under NEC Article 725 for power-limited circuits including speakers, intercoms, and control systems installed in plenum spaces. CMP stands for Communications Multipurpose Plenum and is defined under NEC Article 800 for communications wiring in the same air-handling environments. Therefore, this wire can be legally specified under either NEC article, giving inspectors and AHJs complete flexibility in how they classify the installation. Having both ratings on a single spool also eliminates the need to stock two separate plenum cables for projects that mix audio and communications circuits.

Q: Can this 14/2 CL3P CMP plenum wire be installed in riser shafts as well as plenum ceilings?

Yes — CMP-rated cable carries the highest fire rating in the NEC hierarchy for this cable class, which means it can be substituted anywhere a lower-rated cable (such as CMR or CM) is required. Consequently, this 14/2 CL3P CMP plenum wire is acceptable in both plenum ceiling spaces and vertical riser shafts between floors. However, the reverse is not true — CMR or CM cable cannot legally be installed in plenum spaces. Therefore, specifying CMP-rated wire for an entire building simplifies compliance, eliminates stocking multiple jacket ratings, and reduces the risk of a mis-installed run being flagged during inspection. Always confirm the specific fire-rating requirement for each pathway with your local Authority Having Jurisdiction before installation.

Q: What low-voltage applications is this 14AWG plenum wire suitable for?

This 14/2 CL3P CMP plenum wire is rated for a wide range of power-limited low-voltage applications, including in-ceiling and in-wall speaker systems, intercom circuits, paging and public address systems, access control signal wiring, and security alarm circuits. At 14AWG, it provides sufficient current capacity for speaker runs up to approximately 80 feet at 8 ohms and supports intercom or control circuit runs across typical commercial floor plates. Furthermore, the stranded bare copper construction handles repeated flexing during installation without conductor fatigue. As a result, this single product functions as a versatile low-voltage rough-in cable for AV integrators, electrical contractors, and security installers working on the same project simultaneously.
