[RE-wrenches] 690.64(B) 2008 NEC

[Allen Frishman]

Hi Wrenchers,
I know this topic has been discussed several times but am in need of a little more clarification.

Here is the design:
- Inverter located on roof is grid connected to a ("Main Breaker" sub-panel that feeds multiple loads) via a solar breaker.
- Dedicated set of conductors feeding the Main Breaker sub-panel on the roof are protected in the basement electric room with a fused switch.

The Question:
Since the conductors between the fused switch in the basement & the sub-panel are protected on both ends do they need to comply with the 120% rule?  As a reference the part that is in question is, are these conductors "capable of supplying multiple branch circuits,"?  


All feedback is appreciated!
