The SUPERIOR ESSEX 66-240-3B is a Category 6 Plus (C6+) plenum-rated data cable designed for structured cabling installations in commercial and residential buildings. Constructed with 23 AWG conductors arranged in four twisted pairs, this cable supports high-speed data transmission and meets plenum (CMP) rating requirements, making it suitable for air-handling spaces where fire and smoke propagation standards apply. It is sold as a single unit and is handled primarily by low-voltage cabling contractors and data communications technicians.
This cable is intended for horizontal runs in plenum ceiling spaces, raised floors, and other air-handling environments where CMP-rated cable is required by code. The gray jacket provides standard identification in structured cabling systems. It is commonly specified in new construction and retrofit commercial data network projects where Category 6 or better performance is required for Ethernet and VoIP infrastructure.
Designed as a CMP-rated Category 6 Plus horizontal cable for use with standard 8P8C (RJ45) terminations, patch panels, and keystone jacks that meet or exceed Category 6 performance specifications.
Installation should be performed by a licensed low-voltage cabling contractor in accordance with NEC Article 800 and applicable local codes. Verify that all termination hardware is rated for Category 6 or higher before installation. Avoid exceeding the cable's minimum bend radius and maximum pulling tension during routing to maintain performance ratings. Power down any active equipment at patch panels or switches before terminating cable runs.
