i was thinking about the copper content of a/c compressors i did this one and it had 2lbs num1 and 1lb num2 is 3lbs right for this type? its the tall window a/c one do all motors have 2 different sizes of wire in them? do all compressors of this type have the same amount of copper or does it vary by size of the a/c? do the central a/c compressors have the most weight in copper or is it the smaller ones?
