Review on GS Power 14 AWG: The True American Wire Gauge Solution by Seth Singh

I have ordered this type of wire at least twice. CCA means copper-clad aluminium, i.e. copper-clad aluminum wire. This CCA has one indicator mark per foot of wire and good strand count. Pure copper has a higher ampere capacity for rating measurement, but U often pays more. CCA works well for many automotive wiring jobs where your current requirements are not extreme, or just use a larger CCA reading than U with pure copper. I have soldered many thousands of times and find it almost as easy as soldering a strand of pure copper.
