Maybe so, but AWG is size, not number of strands, including solid wire. So, it is standardized Plus NEC doesn't care how many strands in the wire (solid core and aluminum are rated differently), it still rates them the same.AWG (American wire gauge) hasn’t been standardized. Comparing two different brands in the same gauge might get you the same “size” cable but when you compare the actual stranded wires inside the insulation, I’ve seen as big of a difference as half!
