"There is also NO code requirement to NOT have service conductors NOT accessible in an attic or anywhere else for that matter..i dont think it is that safe because there is no fuse between you and the poco xfmr"
Have you read:
VI. Service Equipment — Disconnecting Means
230.70 General. Means shall be provided to disconnect all conductors in a building or other structure from the serviceentrance
conductors.
(A) Location. The service disconnecting means shall be installed in accordance with 230.70(A)(1), (2), and (3).
(1) Readily Accessible Location. The service disconnecting means shall be installed at a readily accessible location either outside of a building or structure or inside nearest the point of entrance of the service conductors.
There are some jurisdictions that have (in writing) some allowance inside the building.
In general the service entrance conductors are not permitted inside of a building.
Running this in walls as you have stated is not permitted.
