Conn-air w186c-1046 Shielded Riser Cable 18AWG 6C

Product Description

The CONN-AIR w186c-1046 is an 18 AWG, 6-conductor shielded riser cable rated for low-voltage control wiring in commercial and residential HVAC, security, and building automation systems. The cable carries NEC Type CMR and CL3R ratings, qualifying it for vertical riser runs between floors. The FT-4 flame rating confirms it meets vertical flame propagation requirements. With a maximum suggested voltage of 300 volts and a factory-loaded cable box containing 1005 feet of grey-jacketed cable, this product is well-suited for large installations or multi-zone projects where long runs are common.

This cable is used in HVAC thermostat wiring, zone control systems, security panel runs, access control installations, and building automation low-voltage circuits. It is appropriate for in-wall and between-floor riser installations where fire code compliance requires a CMR or CL3R-rated cable. The shielded construction makes it a practical choice in environments with electrical noise or where signal integrity over longer runs is a priority.

Key Features

• NEC Type CMR and CL3R dual ratings for compliant riser installations
• FT-4 flame rating meets vertical flame propagation requirements
• Shielded construction reduces electromagnetic interference on control signal runs
• 18 AWG, 6-conductor configuration suits multi-zone HVAC and low-voltage control wiring
• Grey jacket, 1005-foot cable box simplifies job-site handling and inventory
• 300-volt maximum suggested voltage covers standard low-voltage control applications

Compatibility

Designed as a standard low-voltage riser cable for residential and light commercial HVAC thermostat wiring, zone control panels, security systems, and access control applications requiring NEC CMR or CL3R compliance.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician familiar with NEC low-voltage wiring requirements. De-energize all control circuits before making terminations. CMR-rated cable is required for vertical riser runs penetrating floor assemblies per NEC Article 800 and related low-voltage cable articles. Avoid bundling shielded signal cable with high-voltage conductors to preserve shielding effectiveness.
