Andrew,
It does not exist. We tried like crazy to get it into the 2011 NEC, but to no avail. At the last second the proposal was put on hold until the 2014 NEC. Major bummer. For now it can only be done with AHJ approval. Many allow it but it is not in the NEC. Alternatively you must use the sum of supply breakers no greater than 120%. Much more restrictive. Bill.

I also seem to remember specific verbiage that needs to be on the panel along the lines of "PV circuits only. Do not add load breakers." to ensure compliance with 690.64(B). Does anyone know where I can find this info in the NEC? Andrew Truitt Standard Solar Inc. -- "Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless!" ~William McDonough
