In general, how many service(s) should supply a building or structure?

Explanation:
Having one service entrance is the general rule for a building. The service consists of the conductors and equipment that bring power from the utility to the building and the main disconnect that controls the whole load. A single service keeps metering, protection, and control straightforward and ensures a clear point of supply. There are situations where more than one service is used—such as for multiple separate occupancies or structures with independent meters—but those are exceptions rather than the norm.
