1.1 Scope
This standard covers ac switches rated above 1 kV up to and including 52 kV for use in metal-enclosed switchgear. These switches may be:
a) Stationary or drawout
b) Manual or power operated
c) Fused or unfused
Within this standard, the words "switch(es)" shall be considered to mean three-phase, ac, gang-operated, switch(es) as defined by this scope.
These switches are intended to be installed in an enclosure that provides a degree of protection to the switch and the enclosure may be suitable for indoor or outdoor conditions and complies with the requirements of switchgear assemblies as defined by IEEE Std C37.20.2, IEEE Std C37.20.3, or IEEE Std C37.20.9.
This standard does not apply to switches for use in subsurface or pad-mounted switchgear in IEEE Std C37.74 or to high-voltage air switches in IEEE Std C37.30.1.
