R324.7.3 Locations of DC Conductors
JUMP TO FULL CODE CHAPTER
Conduit, wiring
systems, and raceways for photovoltaic circuits shall be
located as close as possible to the ridge or hip or valley
and from the hip or valley as directly as possible to an outside
wall to reduce trip hazards and maximize ventilation
opportunities. Conduit runs between sub arrays and to DC
combiner boxes shall be installed in a manner that minimizes
the total amount of conduit on the roof by taking the
shortest path from the array to the DC combiner box. The
DC combiner boxes shall be located such that conduit
runs are minimized in the pathways between arrays. DC
wiring shall be installed in metallic conduit or raceways
when located within enclosed spaces in a building. Conduit
shall run along the bottom of load bearing members.
