This is a CCA cable and is much smaller. This ad was written to fool you. It says "OFC" (oxygen free copper) twice, but a light scratch on the wire will strip away the copper plating and reveal the shiny silver core material, which is clearly aluminum. I also measured it to make sure it was big enough for 8 AWG, it should be 0.1285 inch or 3.26mm in diameter and its diameter is much smaller than 2.75mm.
