I Just looked at <R82>, <R83>, <R84>, from last year, and I don't see how an interpretation can be made either way regarding down-stream fusing.

What seems clearer is <R45> which specifically prohibits "Fuse panels different from those provided in the Kit Of Parts".

If you search the 2008 rules for "fuse", it turns out that fuses were specifically allowed. This statement appears in <R45>: "In addition to the required branch power circuit breakers, smaller value fuses or breakers
may be incorporated into custom circuits for additional protection".

I agree with "usbcd36" that it should be a requirement to protect the wire. If you run 20 gauge wire, it makes no sense to try and "protect" it with a 20A breaker. The wire will act as a fuse which is exactly what you don't want.
