Carol C2404A.38.10 Communication Cable

The Carol C2404A.38.10 is an unshielded communication cable designed for audio and control system installations. It features four stranded 18 AWG conductors with PVC insulation and a gray PVC jacket. The cable carries a CM fire rating per NEC Article 800 and is rated for a maximum of 300 volts.

Reel-in-box format for straightforward pulls

Supplied on a 500-foot reel in a box, the cable pays out cleanly during long runs without tangling. Its 0.3-inch outside diameter fits standard raceways and conduit, while the stranded construction eases termination at screw terminals or punch-down blocks. The unshielded design suits environments where electromagnetic interference is not a concern.

Installers running low-voltage audio

This cable suits contractors wiring background music, paging or building automation systems that require a CM-rated, four-conductor solution. Buyers needing shielded pairs for data networks, higher voltage power distribution, or plenum-rated jacket material should select a different product type.

Questions about this item

What is the maximum voltage the 18 AWG conductors can handle in sustained use?

The cable is rated for 300 V maximum, so sustained operation must stay at or below that level.

How much heat does the PVC jacket dissipate when the cable runs all day at full load?

At 300 V the 18 AWG stranded conductors generate modest heat; the 0.3 in PVC jacket passes it to ambient air without active cooling.

Which connectors or termination blocks are needed to use the four unshielded conductors?

The 4 conductor, 18 AWG stranded cores accept standard low-voltage screw terminals, IDC blocks or crimp pins sized for 18 AWG wire.
