Well this is very interesting. The only reason I could see for the inspectors reason would be if you were running from a disconnect to a main lug panel, you would use ser. But you're not. Even if the panel is too far away from the entrance, I think you would be required to install a disconnect before the panel, not simply run ser instead of seu. I don't get it.

I don't do a lot of residential. But when I uppgraded my service to 200 amp, I had to mount a disconnect by the main. I had to run a #6 bare solid CU from the meter (where the N & G bonded together), to the disconnect, and to each of the ground rods, all in one piece. I had to have 2 ground rods 10' apart.From the disconnect to the sub panel was 4 conductors. Anything other, and they would not pass it.

Bob, no disco required, but he wants ser. I dont get it either.
Speedy, EXACTLY. I asked him where to terminate the wire, and he told me to use a double lug, or a single lug tapped to the meter can. I think he is pulling this out his butt. I am going to ask him for written documentation in his municipality that states this requirement. I hope I don't p!$$ him off to bad, but oh well.
