I find myself quite often having 2 authorities overlapping each other on rules and enforcement. Case in point, from the insulator knob down to meterbase. Sometimes my AHJ says he don't like my insulator knob and on same job POCO says its fine. I was always told that the local inspector can only really inspect from main breaker downstream, maybe up to the meter at most. But, in past I have been dinged by local inspector on amount of straps from meter up to service drop and insulator knob. Is there a general rule of thumb where one authority stops and the other starts ???

He can definitely inspect before the Main Breaker. The customer owns and is responsible for everything on his house except the actual glass meter. Definitely the inspector is going to inspect your conduit or cable, straps, clearances, drip loop. I know the POCO here have Porc insultaors and they will give you a fish plate thru bolt eye if you want to use that. (I don't think they pass out the porcelain ones).I find myself quite often having 2 authorities overlapping each other on rules and enforcement.

The inspector can inspect anything he wants to in the installation, but technically he cannot cite the NEC on wiring on the POCO side of the service point.
But to the extent that the POCO wiring interacts with the structure of the house and with the riser, weatherhead, etc. that you install he may be able to justify it.
For sure everything up to the service point must be acceptable to POCO, and they make make rules for connecting service that bleed over onto the NEC side of the service point.
One possible example of the latter is when a POCO prohibits NEC compliant line side taps for PV.
One could argue on behalf of POCO that a line side tap could be considered to be on their side of the ever elusive service point. The lack of clarity in the NEC about the status of a PV disconnect (i.e. not a service disconnect, but....) does not help.
