The SOUTHWIRE P40133-1C is an 18 AWG, 2-conductor shielded automation communication cable designed for low-voltage control and data signal wiring in building automation and HVAC control systems. The cable features a bare copper conductor with PVC insulation and a PVC outer jacket, measuring 0.17 inches in outside diameter. Rated for plenum environments under UL Type CMP and CL3P listings, it meets NEC Article 725 requirements and carries California State Fire Marshal approval. Licensed electricians and controls technicians install this cable in commercial and residential automation applications where signal integrity and code-compliant plenum routing are required.
This cable is suited for building automation systems, HVAC controls wiring, and low-voltage communication runs in plenum-rated ceiling and air-handling spaces. The shielded construction helps protect signal lines from electromagnetic interference in environments with multiple control runs. It is sold in 1-foot cut increments with a minimum cut length of 100 feet, from a 500-foot total coil. This makes it practical for both short control runs and longer trunk wiring on commercial jobs.
Designed as a plenum-rated, shielded 18 AWG 2-conductor communication cable suitable for NEC Article 725 Class 3 low-voltage automation and HVAC controls wiring applications.
This cable is typically installed by licensed electricians or controls technicians following NEC Article 725 and applicable local codes for low-voltage communication wiring. Power down all associated control circuits before terminating or splicing. When routing through plenum spaces, verify that the CMP plenum rating meets the requirements of the authority having jurisdiction. Avoid sharp bends and mechanical stress points that could compromise the shield continuity.
