Outdoor
Temperatures
for Selected U.S. and
Canadian Cities and
Temperatures Inside
Raceways on Rooftops
Exposed to Direct Sunlight
Introduction
The National Electrical Code Section 310.15(A)(3), and good
design practice, requires adjustment of ampacity of wires and
cables installed in ambient temperature conditions that are
higher than those upon which the listed ampacities of Table
310.15(B)(16) are based. Ambient temperature is understood
to mean the temperature of the air surrounding the conductor.
For conductors in raceway, the ambient to which the insulated
conductor is subjected is the temperature of the air inside the
raceway.
Ambient temperatures within raceways above rooftops will
vary with height, in accordance with Table 310.15(B)(3)(c).
After determination of the resultant ambient temperature within
the raceway, Table 310.15(B)(2)(a) should be applied.
To help determine the temperature insulation will be subjected
to—under unloaded conditions—CDA has compiled a table
of average outdoor temperatures for various U.S. and selected
Canadian cities, as well as temperatures inside raceway on and
at various heights above rooftops in accordance with Table
315(B)(3)(c).
For each city, the table contains:
n An
average of the 2% ASHRAE design temperatures for
each location for June through August*
n Likely
resultant temperatures inside rooftop raceway
(unloaded) exposed to direct sunlight in accordance with
Table 315(B)(3)(c):
n On
the roof, and up to ½ inch above roof
n Greater
than ½ inch and up to 3½ inches above roof
n Greater
than 3½ inches and up to 12 inches above roof
n Greater
than 12 inches and up to 36 inches above roof
n ASHRAE’s
reported “extreme annual design condition”—
i.e., the maximum dry-bulb temperature reading for the
location expected within a 50 year period.

he following table indicates the 2% design temperature
(averaged for June-August) for various cities and the various

The first column represents the ASHRAE 2% design temperature
averaged for June - August.1 The second through fifth column is
the resultant ambient temperature inside the raceway unloaded at
specified heights above the roof.2 The right-hand column is the
maximum dry-bulb design temperature for that city, based on 50
years distribution of weather data.

1. ASHRAE bases its “warm-season temperature conditions”
for each city on annual percentiles of 0.4%, 2 %, 5% and 10%.
As an example, the June 2.0% dry-bulb design temperature for
Atlanta is 91.7°F. Therefore, based on a 30-day month (i.e.,
720 hours), the actual temperatures can be expected to exceed
91.7°F for total of 14 hours a month. The corresponding 5.0%
design temperature (89.3°F) can be expected to be exceeded for
36 hours a month; while the 0.4% design temperature (94.7°F)
can be expected to be exceeded for 3 hours a month.
2. Calculations shown in the table are based on ASHRAE 2%
design temperatures for 10 years of data* and CDA research
covering over five years of monitoring air temperatures inside
rooftop raceways.** The table uses the average of the June
through August dry-bulb design temperatures—generally
the hottest months of the year—in calculating the design
temperatures in this table. All temperatures are rounded to the
nearest whole number. The results can then be used to apply
the correction factors in Table 310.15(B)(2)(a) of the National
Electrical Code.
*ASHRAE has compiled 10 years of dry-bulb design
temperature data in the 2009 ASHRAE Handbook of
Fundamentals (The American Society of Heating,
Refrigerating and Air-Conditioning Engineers. Chapter 14,
Climatic Design Information). The table covers most of the
U.S. and selected Canadian weather station locations included
in the ASHRAE Handbook. The complete Handbook can be
ordered directly from ASHRAE (www.ashrae.org). (CDA
recommends the CD format, Product Code 81092, to obtain
complete climatic conditions.)
