Also, you're still going to want to size the power drop so that the measured load won't exceed 80% capacity due to code.

that's true of output breakers, panel busbars, and wire. on the other hand, transformers (e.g., 480->208 or 12K->480) are rated at 100%, as are input breakers and of course generators. -- Paul Vixie
