Standard

The standard outlined, draft ANSI/IEEE C37.21-1985, covers ratings, construction, and testing of dead-front control switchboards containing but not limited to devices such as switches, control devices, instrumentation, metering, monitoring, protective and auxiliary relays, and regulating devices and accessories. It includes, but is not specifically limited to, switchboards for the control and protection of apparatus used for or associated with power generation, conversion, transmission, and distribution. It does not apply to 1) industrial controls, 2) communication equipment, 3) switchboards for use on board ship, 4) Class 1E switchboards for use in nuclear generating stations, nor 5) does it address human factor considerations.<>
