New IEEE Standard – Inactive – Superseded. This IEEE Standards product is part of the C37 family on Switchgear, Substations and Protective Relays. 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 are covered. Switchboards for the control and protection of apparatus used for or associated with power generation, conversion, transmission, and distribution are included, but the standard is not limited to these. Industrial controls, communication equipment, switchboards for use on board ships, Class 1E switchboards for use in nuclear generating stations, and human factors are not considered.
