scope:

This standard applies to switching devices, interrupters, and interrupter switches (as defined in IEEE Std C37.100™) for alternating current, rated above 1000 V and used indoors, outdoors, or in enclosures for which a switching rating is to be assigned. While this standard covers the basic requirements of interrupter switches used indoors, outdoors, and in enclosures, other standards such as IEEE Std C37.20.2™, IEEE Std C37.20.3™, IEEE Std C37.20.4™, and IEEE Std C37.74™ also contain requirements for switches used in enclosures. This standard does not apply to load-break separable insulated connectors, which are covered by IEEE Std 386™-1995 [B8].¹ This standard also does not apply to circuit-breakers, circuit-switchers, or reclosers.
