(c) Conduits Exposed to Sunlight on Rooftops. Where
conductors or cables are installed in conduits exposed to
direct sunlight on or above rooftops, the adjustments shown
in Table 310.15(B)(2)(c) shall be added to the outdoor temperature
to determine the applicable ambient temperature
for application of the correction factors in Table 310.16 and
Table 310.18.
FPN: One source for the average ambient temperatures in
various locations is the ASHRAE Handbook ? Fundamentals.
