I believe that the EGC in any cable is sized to the requirements of the ungrounded conductors but what I can't find is if it is sized to 250.122 or 250.66. Since this is "service" cable it might actually be sized to 250.66 which exceeds 250.122. I am going to dig around in the shed and see what I have in the way of SE cable and see what the EGC looks like to me twisted up round.
