OK, Thanks Ray. I missed that. The call out is still smaller than #6, 
not #4, but your point is well taken and much appreciated. 

Interesting stuff.  So as long as you use USE-2/RHW-2 or similar all the 
way thru from module to inverter, you can mark #6 or smaller, but if you 
transition to THHN or similar, in a box on the roof for instance, the #6 
or smaller has to be factory colored.
