Default Consumer service or feeder?

I want to know what you all think. Or can Confirm. #2 AL for a 100 amp single family home service is ok because 4-004 (22) and Table 39. the definition of "service conductor" is up to "service Box". so after Service box conductor must be sized with tale 2 or 4. Now.. I have a 100 amp fuseable disconnect outside the house right after the meter. the new panel is in the center of the basement (65 feet away) so I need overcurrent protection outside because rule 6-206 (c). IS THE CONDUCTOR FROM OUTSIDE TO THE PANEL ALLOWED TO BE #2 AL? or is it a feeder now? I have in the past "got away with it". a new service entrance rated auto transfer was installed outside next to the meter and the conduit and wire feeding the panel was just moved into the new switch. it was left a # 2AL and passed... I didn't think about it at the time.

It can be sized using table 39.

Table 39
Minimum permitted size for 3-wire 120/240 V and 120/208 V service conductors for single dwellings and feeder conductors or cables supplying single dwelling units of row housing, apartment, or similar buildings and terminating on equipment having a conductor termination temperature of not less than 75 °C


Notes:
1) This Table applies only to conductors sized for loads calculated in accordance with Rules 8-200 1) a), 8-200 2), or 8-202 1).

If the pony panel is for an apartment or something similar and you used 8-200 1) a), 8-200 2), or 8-202 1), because those loads are not continuous loads, you can use table 39.
If it is a pony for a garage or something similar then it is a continuous load and you can not use table 39.

Sure . that was a hypothetical. the way I read it the service conductors will end at my fuseable disc. outside because it is the service box. anything after is considered a feeder. but in reality this is not the case

It's a feeder.
Your service conductors end at your disconnect.
If as you say your service conductors end at the disconnect how can you come up with the idea, that that location is anything but your service point. In reality the panel inside is a sub and not your service disconnect
Remember to remove the bonding jumper on your panel as it is now classified as a sub panel

What is wrong with using #1 instead of #2? I'd go with #1 size cable because 9 times out of 10 the owner will find something else to install later on down the road like an ac unit...

Under table 39 we can use 4/0 aluminuim for a 200 amp service but we can only load it to 189 amps and have to label it... so we did the last service upgrade with 250mcm... looks pretty funny next to the poco #4 aluminum, but the owner can load it right up if they want.

I'd use the #1 aluminum and call it done.
