Service Disconnect Question

[WA_Sparky]

I'm working on a project (SLC Utah). Essentially a large shopping complex with a few detached buildings in the middle of the parking lot. Shell engineer is designing the site infrastructure where all building (main and detached buildings) meters and disconnects are located in the main building.

Wouldnt it be a code violation for one service to pass through another building?
Or is this one of those "NEC Vs utility definition of a service" since they are all metered tenants?
I was asked just to locate where it will enter my building and refer to their plans. At the very least id imagine I would need a disconnect or a sign indicating where the disconnect is located in the case of an emergency.

Maybe its an AHJ sign off thing.. just doesnt feel right.

Thanks,

There are restrictions on services but from your discription you have feeders and there is no restriction.

The wording in 230.3 is rather poor, especially considering the existence of 230.70(A)(1) which would generally prohibit service conductors from "passing through" a building even without 230.3. To me "pass through" implies they do not end, so if that is the case, one could hit a service disconnect and then leave the building with a feeder to feed the served building.

If you can route SE conductors underground then you are outside the building....

In my mind the question is if you have unfused service conductors passing through one building to get to another.

As Augie stated your condcutors to the other buildings are feeders since your service disconnects are in the main building. Feeders can pass through a building. Regarding the detached buildings each of those requires a disconnecting means for the feeder nearest where the feeder enters the building.

What would make this non compliant is if say you had some sort of tap box inside the first building located ahead of the service disconnect(s) and supplied the second building(s) directly from that tap box.

If you hit a service disconnect before you leave the building to go to other building(s) those conductors are not service conductors they are feeders (or possibly feeder taps).
