Ratings and Test Requirements
The voltage rating of the switchgear shall be [15.5 kV][27 kV][38 kV][as
indicated]. The corresponding ratings associated with the required
switchgear voltage rating shall be as follows:
**************************************************************************
NOTE: The following optional ratings are available
for switchgear assemblies, however, specifying these
1. Optional short-time and short-circuit
interrupting current ratings of 16,000 rms
symmetrical amperes is available for both two and
three position switchgear assemblies.
2. Optional short-time current rating of 25,000 rms
symmetrical amperes is available for switchgear
assemblies configured with load interrupting
switched ways only.
3. For Norfolk Naval Shipyard projects, select
optional 25,000 rms symmetrical amperes short-time
current rating for switchgear assemblies that are to
be installed on the 11.5 kV system.
