I understand the "rule of six" per structure (230 (F) in the 96 NEC). It just seemed like the question had multiple service disconnects for one residence in a multi-occupancy structure.
The question seemed to be awkwardly worded - Even though term service disconnect was being used, it seemed to me that George could be inadvertantly referring to branch circuits for each occupancy within a multi occupancy structure, rather than "main d/c's" that would control power to a sub-panel located inside each occupancy.
That's why I was surprised/confused.
BTW - I second the recommendation for the NFPA Code Handbook. EXCELLENT reference / explanatory material.
