I agree with John.
Many times I have responded to "just put in whatever the Code minimum is...I don't want to just throw money away" with my canned response:
"I can design an installation that will meet every Code requirement, but even the Amish will be blowing fuses".
There are a lot of folks out there who fail to understand that the Code is concerned with Fires and Electrocution.
If you don't have enough power to run your appliances...that's a separate problem.
That's why I always look over and above the minimums in my designs...yet there are still an awful lot of cheapstakes out there who want just the bare minimum.
BTW, in Chicago installing a microwave oven invokes the Plumbing Code (you need a grease trap installed at the teeny little sink).
