Joe,

Had a Doctor for a customer that added an X-ray machine to his practice. That equipment needed a 3 phase service, so we ended up with 120/240 single phase service and a 120/240 3 phase 4 wire service to the same building.

Another contractor ended up doing something similar on a truck stop remodel to keep from building a 400 amp 3 phase service. Built two 200 amp services like the example above and saved the owner some money.

You're on your own for "such as"

Few things are harder to put up with than the annoyance of a good example.
