The National Electrical Code (NEC) regulates (covers) everything electrical that is *permanently *attached to your house (or your garage) or business. This is the regulatory scope of the NEC.

Items that are not permanently attached to your house are not within the regulatory scope of the NEC. A toaster is not regulated by the NEC because it is not permanently connected or attached to your house. Your toaster is a plug-connected appliance, and thus not within the scope. A lighting fixture is within the scope of the NEC because it is attached to your house. However, the wiring going from your meter to the utility pole is not regulated by the NEC. After the meter is, but wiring before the meter (service entrance conductors) is regulated (rather loosely, I might add,) by the utility.

You can have whatever receptacle you may wish attached to your house. Your ultimate use of that receptacle matters not to the NEC. If the electrical inspector asks what the receptacle will be used for, you can answer, "I'm not sure yet. I heard that 240 was good to have on your garage, so that is why I had it installed."

Article 625 somewhat attempts to stretch the regulatory scope of the NEC, but if you read the article carefully, it actually does not. If you put a receptacle outside your garage, adjacent to your driveway, you have to follow all the rules for installing such an outlet. Nothing more or less. After the work has passed inspection you can plug in anything that you care to into that outlet, end of story.

In most municipalities you can, as a homeowner, pull a permit to perform electrical work on you own house. These "homeowner" electrical regulations vary widely from place to place, however.
