Conn-air w183c-2058.5rib 18 Awg 3-conductor Plenum Cable

Product Description

The CONN-AIR w183c-2058.5rib is an 18 AWG, 3-conductor plenum-rated shielded stranded control cable supplied in a 500-foot spool. Plenum-rated jacketing meets low-smoke and flame-spread requirements for installation in air-handling spaces, making it compliant for use in HVAC duct systems and ceiling plenums. The stranded conductors provide flexibility during pull-through installations, and the overall shield helps reject electromagnetic interference in signal and low-voltage control circuits. HVAC technicians and electricians install this cable in commercial and residential control wiring applications where code requires plenum-rated materials.

This cable is suited for low-voltage control wiring in HVAC systems, including thermostat runs, zone valve control, building automation sensor wiring, and other signal-level applications routed through plenum air spaces. The 500-foot spool length reduces the number of splices needed on larger commercial jobs. Stranded construction makes termination straightforward at control boards, zone panels, and field devices.

Key Features

• 18 AWG stranded conductors for flexibility and ease of termination
• 3-conductor configuration supports standard low-voltage control circuits
• Plenum-rated jacket meets low-smoke, low-flame-spread requirements for air-handling spaces
• Overall shield reduces electromagnetic interference on signal and control runs
• 500-foot spool minimizes field splices on long or multi-zone runs

Compatibility

Designed as a plenum-rated low-voltage control cable suitable for HVAC thermostat wiring, zone control, and building automation applications where NEC Article 800 or CMP-rated cable is required in air-handling spaces.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with the National Electrical Code (NEC) and local authority having jurisdiction requirements. De-energize all connected control circuits before terminating or splicing. Maintain bend radius minimums during pull-through to avoid damaging the shield or conductor insulation. Do not route low-voltage control cable in the same conduit as line-voltage wiring without verifying NEC separation requirements.
