One service/two buildings

[alixenos]

Hi,

I'm trying to power a two building project from one new services.

where in the code I have to look to power such scenario?

Whats the typical way of providing power to multiple building through one service?

Thank you

Well one way is you could group two service disconnects at the service point and run a outside feeder to one or both buildings. See Article 225 and Article 230

If it is truly two buildings (separate structures or separated by an approved fire wall) you can actually run a separate service from the service point to each building. This is advantageous as each building would have power in the event the other building did not (fire, etc).

If it is separate occupancies (structurally one building) 230.40 exception will allow you to run a set of service conductors to each occupancy from the one service point to each occupancy.

Most common install here is as tortuga notes: a service point with meters and disconnects with feeders to each occupancy.

Even If it's not residential?

I don't see where the Code differentiates...one building=one service

See 230.40. you can only serve one set of service entrance conductors, and I don't see an exception allowing two non Residential sets that are not grouped

I think you can essentially do that for article 547 buildings.
