If it sounds too good to be true, it might be. Don’t get too excited if you find Category 6 cable available online for practically half what you’ve been paying for that brand name. Even if it claims TIA-568-C compliance, includes the UL listing mark and even has a ETL verification legend printed right on the cable, make sure that cable isn’t made with copper clad aluminum (CCA). Cables made with CCA conductors are simply not worth the risk, even at the lower price. Not only are they non-standards compliant, but they often do not have a valid UL safety listing per the National Electric Not Worth the Savings or the RiskCode (NEC).
