This corrigendum corrects an error where the user of this document was directed to gather the wrong column information from the NOAA website for use in calculations. The document erroneously directs the user to read from the monthly normal average temperature values from the website rather than the monthly normal maximum temperature values.

Guide for Evaluating the Effect of Solar Radiation on Outdoor Switchgear
The guide provides data in current-temperature and tabulation form for use in evaluating the effect of solar radiation on outdoor switchgear. The guide applies to switchgear as defined by IEEE Std C37.20.1™, IEEE Std C37.20.2™, IEEE Std C37.20.3™ and IEEE Std C37.20.9™; control switchboards as defined by IEEE Std C37.21™; metal-enclosed bus as defined by IEEE Std C37.23™; medium-voltage ac controllers as defined by UL 347; motor control centers as defined by UL 845; switchboards as defined by UL 891; and medium-voltage air-insulated circuit breakers for outdoor application defined by IEEE Std C37.04™.

IEEE Guide for Evaluating the Effect of Solar Radiation on Outdoor Metal-Enclosed Switchgear
Information to assist in evaluating the effect of solar radiation on outdoor metal-enclosed switchgear including metal-enclosed bus and control switchboards is provided in this guide. Specific data in the form of a continuous current capability factor for specific maximum monthly normal temperatures at the installation location to adjust the continuous current capability of outdoor metal-enclosed switchgear to the solar radiation condition required are given in this guide. Examples of maximum monthly normal temperatures along with sources for data for the US and for Canada are also presented in this guide.

IEEE Guide for Evaluating the Effect of Solar Radiation on Outdoor Metal-Enclosed Switchgear
This guide provides information to assist in evaluating the effect of solar radiation on outdoor metal-enclosed switchgear including metal-enclosed bus and control switchboards. Specific data are given in the form of a continuous current capability factor for specific maximum monthly normal temperatures at the installation location, to adjust the continuous current capability of outdoor metal-enclosed switchgear to the solar radiation condition required. Tables of maximum monthly normal temperatures at various locations in the US and Canada are provided.
