I have a question on services to a multiple occupancy building. This has been a bit confusing to me for a long time and has reared it's head again.
I have a large building which has been concerted to multiple occupancy (retail shops).
The original service was a 1200 amp fed from a pad transformer. It now feeds one occupancy.
The building has been divided with fire walls rated at 1 or 2 hour only, but each occupancy now has it's own panel fed from the original pad transformer (directly).
230.2 states that a building shall be supplied by one service (with exceptions, of course), however, in the '08 handbook under 230.2, Figures 230.11 and 230.13 seem to indicate the multiple occupancy arrangement allows for the separate laterals to each occupancy.

Input requested.

230.2 Number of Services. A building or other structure served shall be supplied by only one service unless permitted in 230.2(A) through (D). For the purpose of 230.40, Exception No. 2 only, underground sets of conductors, 1/0 AWG and larger, running to the same location and connected together at their supply end but not connected together at their load end shall be considered to be supplying one service.

Does'nt the last sentence answer your question?
