I'm requesting viewpoints on the following installation.
A PV installer has used individual type USE-2, Sunlight resistant conductors from the PV array to the DC disconnect. The individual conductors operate at approximately 400-volts and travel a distance of approximately 90 feet from the array to the disconnect. During that distance they are exposed briefly on the roof, continue traveling behind concrete tile 'eave' shingles, finally traveling, exposed, on the underside of the eave being secured to the truss tails. From the eave height the conductors travel in EMT to the DC disconnect.
Violation or compliant? Please cite reference based on 2002 NEC.
Thanks,
Joe Jones
