9. MIL-DTL-32483A MED VOLTAGE SWBRDs
Switchgear, Power, Hard-Mounted, Medium Voltage, Naval Shipboard
In Review
Revisions based on the expected trend for new construction programs to generate medium voltage (>1000 volts).
Updated requirements for jam nuts, lock wahsers and other fasteners, maximum compartment temperature requirements, fusing, thermal imaging windows and other lessons-learned from 2014 meeting with switchboard technical community.
DISTRIBUTION STATEMENT A. Approved for public release. Distribution is unlimited.

10. MIL-DTL-xx653 LOW VOLTAGE SWBRDs
Switchgear, Power, Shock-Mounted, Low Voltage, Naval Shipboard
New - In Review
Created to establish standard construction, testing, and safety requirements for shock-mounted low voltage switchgear that will result in consistent vendor pricing from program to program.
Originally intended to use commercial specifications as a baseline and publish through a commercial governing body.
Considered revising MIL-DTL-16036M to include requirements for shock-mounted low voltage switchgear.
Concluded that commercial specs and 16063M were not readily adaptable for Navy shock-mounted requirements.
DISTRIBUTION STATEMENT A. Approved for public release. Distribution is unlimited.
