This standard covers assemblies of switch gear devices such as switches, interrupting devices, control, instrumentation and metering, protective and regulating equipment, enclosed bus with associated interconnections, enclosures, and supporting structures. It includes, but is not specifically limited to, equipment for the control and protection of apparatus used for power generation, conversion, transmission and distribution, such as:

Metal-clad switchgear Station-type cubicle switchgear

Metal-enclosed low-voltage power circuit breaker switchgear

Metal-enclosed interrupter switchgear Metal-enclosed bus

Switchboards, including combined boiler turbine- generator boards and miscellaneous power plant boards

Assembled switchgear components of unit Substations

Basically this standard is concerned with enclosed, rather than open, switchgear assemblies. It does not apply to equipment covered by industrial covered by industrial control standards, communication switchboards and communication switching equipment, or switchboards for use on board ships.
