The SUPERIOR ESSEX 55-799-20 is a high pair count non-plenum rated cable designed for low-voltage communication and control wiring applications. This cable is sold individually as a single unit and is intended for installation in standard non-plenum environments where plenum-rated jacketing is not required by code. Trade electricians and low-voltage cabling contractors install this type of cable in residential and light commercial settings where signal integrity and organized pair counts are essential for reliable performance across extended runs.
This cable is suited for use in non-plenum spaces such as wall cavities, conduit, and standard raceway systems that do not require smoke or flame-retardant plenum ratings. It is appropriate for structured wiring, building automation control circuits, and communication backbone runs where a high pair count conductor is needed. Installers working on telephone, data, or low-voltage control systems will find this cable appropriate for those applications.
Designed as an OEM-style replacement and standard installation cable for high pair count non-plenum low-voltage wiring systems in residential and commercial environments.
Installation of this cable should be performed by a licensed electrician or qualified low-voltage technician in accordance with applicable NEC requirements for non-plenum wiring spaces. Confirm that the installation environment does not require plenum-rated cable before proceeding, as substituting non-plenum cable in air-handling spaces may violate local code. De-energize all circuits in the work area before terminating conductors. Use appropriate cable management and pulling techniques to avoid damaging the jacket during installation.
