Big Lie! And not safe!Fraud Claim:This is not as claimed or shown in picture -- it is NOT copper. It's aluminum painted to look copper. The industry marketing word is "copper clad aluminum" or just "CCA copper", which is like genuine faux leather (faux means "fake"). They should call it genuine faux copper as "clad" got nothing to do with it. Just copper color painted over aluminum to hide!By the way, the cross section of wire in picture show true copper. But that's not what it looks likeNot Safe:A We didn't know this and actually tried to cold crank large heavy duty truck require 2800 CCA. The plastic jacket got hot on one end and burned!B Scraping away burned area a bit and looking at wire carefully, we saw it was really just aluminum painted copper. We then went to standard voltage drop calculator widely used in industry to calculate drop also can do many free websites.Use 12.75v DC in voltage drop calculator, use 1 for power factor, 3000A, 20ft for length, use aluminum type wire will clearly say this will not safe to carry 3000A.
