IEEE C37.24-2017

The general information in this guide is intended to assist in evaluating the effect of solar radiation on outdoor metal-enclosed switchgear, and is, for example, applicable to outdoor metal-enclosed circuit breaker power switchgear, metal-clad switchgear, metal-enclosed interrupter switchgear, metal-enclosed gas insulated switchgear, control switchboards, metal-enclosed bus, and pad-mounted switchgear. Specific data are given in current-temperature relationship, and tabulation form for its application to outdoor metal-enclosed low-voltage power circuit breaker switchgear, outdoor metal-clad switchgear, and outdoor metal-enclosed interrupter switchgear.
