If I have FEEDERS inside building and they are concrete encased then are they considered outside? What code section? Note I mean Feeders Not Service conductors.
 
Article 215 doesn't necessarily mention anything in regards to feeders being incased

See 225.32

225.32 is about location of disconnect. 225.32 says for the purposes of this section 230.6 applies. So I take it that means for purpose of location of the disconnect means 230.6 can apply. Nothing about feeders being conrete encased they are outside. Its about location of disco.

However I dont follow how you see 225.32 in combo with 230.6 says if feeders are concrete encased then they are considered outside?
 
This wouldn't happen to be another situation where you have feeders running through unrelated units to get to where they are going and the requirement for outside disconnects?

I see 230.6 as a way out of 230.3 which disallows feeding one building through the interior of another. In that case, you can consider 2" concrete encasement as not being inside the building. Similarly, 225.32 lets you use the concrete encasement rules of 230.6 to allow the disconnect to be further within a building because it isn't inside until the concrete encasement disappears.

But I wouldn't say that pouring concrete around feeders automatically makes them outside unless they are under a poured floor in the dirt. Neither would running feeders through an interior planting space with some dirt necessarily make it a buried feeder.

I think you're in a grey area here. Get with your inspectors and decide how this should be handled in your area. One could argue that the 230.6 definition applies to everything (branch circuit, feeder, service), but I would disagree with that.

What you are saying above imagine this scenario: one long building has two electrical rooms, one story and no firewalls in between. Service comes in electrical room 1 underground where it feeds swbd main breaker. The swbd has feeder breaker that connect to feeder which goes underground, below the floor of the building and comes up in electrical room 2. So let me understand what you are saying: Its the same building but By your point of view feeders are outside and 225 applies?

Hmmm 230.70 does Not refer to 230.6 so it could be what you are saying?

Why would you need it to be considered outside the building?

I dont follow. Any conductors routed inside the building are inside normally but then code amends that for service conductors. Code is different. I dont know what code says if feeders are inside building concrete encased are they considered outside or not

No Code says it's outside. But I still don't follow why you would even care.
