Copper clad aluminum is about ten times more resistive than copper. So if you are looking at this14 awg wire because you want to handle high current (why else do you need heavy wire?) then keep on looking. Google a wire gauge resistance chart and you will see that one thousand feet of 14 AWG true copper wire has a resistance of about 2.5 ohms, while this copper clad aluminum wire is approximately 25 ohms per 1000 feet. You should care about this, you are paying for 14 AWG and effectively getting only 24 to 22 AWG (very thin). Ohms law doesn't lie, one foot of this wire yielded a 300mV loss while carrying 12 amps = 25.6m Ohms, so that works out as 25 ohms per 1000 feet.
