Thanks everyone for kicking in. See I've done a couple of 1200A and 400A services on these McMansions all over the north shore of Chicago. But I've never had to put The supply wire from ComEd's Pole to my meters.
I've seen them hook up to all my services with Cables significantly smaller that 500's on a 400A service. So I just don't want to goof up and have to re-pull larger cables if the AHJ says no.
So thanks all for chiming in. also take a look at this paragragh of Article 310.6
"120/240-Volt, 3-Wire, Single-Phase Dwelling Swervices and Feeders. For dwelling units, Conductors listed in Table 310.15(B)(6), Shall be permitted as 120/240-volt, 3-wire, Single Phase service-Entrance Conductors, Service Lateral Conductors, and feeder conductors that serve as the main power feeder to a dwelling unit and are installed in raceway or cable with or without an equipment grounding conductor. """FOR APPLICATION OF THIS SECTION, THE MAIN POWER FEEDER SHALL BE THE FEEDER(S) BETWEEN THE MAIN DISCONNECT AND THE LIGHTING AND APPLIANCE BRANCH-CIRCUIT PANELBOARDS(S). The feeder conductors to a dwelling unit shall not be required to be larger than their service-entrance conductors. The grounded conductor shall be permitted to be smaller than the ungrounded conductors, provided the requirements of 215.2, 220.22 and 230.42 are met.
So here's how I want to disect this paragragh.
Notice in the beginning of the para. that the code mentions three kinds of conductors
SERVICE-CONDUCTORS
SERVICE-LATERAL CONDUCTORS
AND FEEDER CONDUCTORS,
It puts a comma after each type and ends the sentence "that serve ase the main power feeder to a dwelling."
Then continues to Define the main power feeder. So by reading the difinition of feeder as stated here as going from the main disconnect (meter) to the panel boards so it doesn't count as petaining to going from the supply pole to the meter.
So if you're opposing my thoughts how many times have you gone to a house and upgraded the service from a 60 or 100 to a 200. And say it's overhead. We stick our meter on put up a riser, throw in a couple of 3/0 and "hook up to whatever is there" and the inspector will come over and check your work and hopefully check it off.
Am I making any sense?
