According to a few posts in this thread (5+ GA Wire?
) that '5+ gauge' wire is an oversized type that was made by Scoche.
Being a licensed Master Electrician in multiple states, I get a kick out of these types of cables. There are no "+" sizes in the American Wire Gauge (AWG). It’s all just marketing - that could explain the usage of only 'GA' on that red cable and not 'AWG'.
However, that means the 4 AWG wire could still be the correct diameter, because the '5+ gauge' (LOL) is oversized & therefore doesn't have to meet any type of official standard.

When talking about the official
American Wire Gauge standard - that would be correct. Stranded wires are actually calculated by the equivalent cross sectional Copper area - but it's essentially the same principal. http://en.wikipedia.org/wiki/American_wire_gauge
