Conn-air w184c-2059.5rib 18/4C Shielded Plenum Cable 500ft

Product Description

The CONN-AIR w184c-2059.5rib is an 18 AWG, 4-conductor stranded shielded plenum-rated communication cable supplied in a 500-foot pull box with a white jacket. Plenum-rated construction meets the fire and smoke requirements for installation in air-handling spaces, making it suitable for low-voltage control wiring in commercial and residential HVAC systems. The stranded conductors allow for flexible routing through tight conduit runs and around equipment. The foil shield provides protection against electromagnetic interference, which is critical in environments with variable-frequency drives, motors, and other noise-generating equipment.

This cable is used in low-voltage HVAC control applications including thermostat wiring, zone control boards, damper actuators, and building automation system field devices. The plenum jacket rating makes it the required choice when routing through ceiling plenums, raised-floor air returns, or other environmental air spaces where standard PVC-jacketed cable is not code-compliant. The white jacket is common in commercial installations where cable identification and aesthetics matter. HVAC technicians, controls contractors, and building automation installers are the primary trades working with this product.

Key Features

• Plenum-rated jacket meets fire and smoke propagation requirements for air-handling spaces
• 18 AWG stranded conductors for flexible routing in conduit and through structural members
• 4-conductor configuration covers standard thermostat and zone control wiring needs
• Foil shield reduces electromagnetic interference in noisy mechanical rooms
• White jacket for clean appearance in commercial installations
• 500-foot pull box minimizes jobsite waste and simplifies inventory management

Compatibility

Designed as an OEM-style plenum control cable for use with low-voltage HVAC thermostats, zone controllers, damper actuators, and building automation field devices requiring 18 AWG 4-conductor shielded plenum wire.

Installation Notes

Installation of low-voltage control cable in plenum spaces is governed by NFPA 90A and the NEC, which mandate CMP-rated (plenum) cable in environmental air-handling spaces. De-energize all control circuits before making terminations. Use proper cable staples or J-hooks rated for plenum environments and avoid overtightening fasteners on stranded cable to prevent conductor damage. The drain wire on the foil shield should be terminated to ground at one end only to avoid ground loops.
