Whenever the service is remote as out on a pedestal, then the building would have a feeder and not a service going to it.

Also any off grid supplied application. See art 100 definition of Service. No serving utility, no service.
So should the service drop from a transformer on a pedestal supplying a building should not be called service drop, Correct?

Where is the service disconnect? If on or in the building then it sounds like a service drop to me. And do you mean "pole" not "pedestal"?

This is a pedestal or a type of one.
If it has a disconnect then it is the service. If there is just a meter and then it goes to the building then they are service conductors. Service conductors are the wire before the first disconnect.
I was watching mike holts video (2017) He mentioned that some buildings have services and others dont but are fed with feeder wires and I understand that. I was trying to fing examples of buildings other than remote buildings being feed by feeders. ThanksThis is a pedestal or a type of one.

If it is fed by utility it is service. If the supply conductors are anything besides directly from a utility it is either a feeder or a branch circuit.
Not really anything else to it. Supply to a building will be one of those three things.
On site supply of any kind - the conductors from the supply will be either feeders or branch circuits, never will be service.

I'm not sure of your definition of "building", but every (?) mobile home gets power via a feeder. That's where the quad "mobile home feeder" gets its name.

So you’re saying if you had an off-grid house, with say solar and generators, none of article 230 would apply, and everything would be sized as a feeder?
Bonding and grounding would still have to structured as if you had a service.

You either ground the source or the first disconnecting means. If the source is from a separate structure you normally still run separate grounded and EGC and you bond/ground the EGC at the second structure. And yes nothing in 230 would apply because you don't have a service. Though art 225 part II has many similarities to some portions of art 230.

I did an off-grid commercial project, run off a 3-phase generator.
I bonded the first disco, just as if was a service.
Only thing between the disco and genny is about 15' of generator cable.

You should still have had an EGC to run back to bond the frame of that generator, and not have a bond at both generator and first disconnect.
