Copper Clad Aluminum Cable Conductors Cause Concern


Contractors Beware! The Communications Cable and Connectivity Association (CCCA) and the Copper Development Association (CDA) have put out a warning on Cat 5e and Cat 6 cables being sold in the U.S. made with copper clad aluminum conductors. These cables violate NEC codes, UL 444 (safety standard) and TIA 568C.2 which all require solid copper conductors for multi-conductor comm. cables. If you install cables in buildings that require valid safety ratings (CM, CMR, CMP, etc.), these cannot be legally installed. How can you tell if you have received “faux” cable? Simply scrape the conductor – if the “copper” comes off and exposes a bright silver aluminum conductor, you do not have industry compliant product.

    The performance of Copper clad aluminum is a better conductor compared to solid copper as the frequency of transmission increases. The claims by the CCCA are invalid because the standard committees responsible for qualifying these conductors have refused to preform the test. Independent test however have proven them extremely successful and at a cost reduction of over 50% foot of installed cable and a lower use of a natural resource, copper, it is an excellent choice

    I prefer all copper as I sometimes have to run with lots of “bend” and I don’t want the uncertainty of brittle Al.
