Description / Abstract:
This standard covers assemblies of switch-gear devices such as switches, interrupting devices, control, instrumentation and meter- ing, 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 control standards, communication switchboards and communication breaker switchgear switching equipment, or switchboards for use on board ships.
