A single pole connector which meets the environmental and test
requirements of the MIL-C-24368 and the additional requirements
identified in OPNAV 11320 (latest edition).
A UL 486A listed lug.
An equivalent or better connector as approved by Navy technical
authority.
Figure 13-17. Low-Voltage (480 Volt) Shore Receptacle
13-6.1.2 Low-Voltage In-line Connections. In-line single pole connectors and lug to
lug connections shall meet the same requirements identified in paragraph 13-6.1 above.
Male and female cable mount in-line connectors may be used to connect shorter cable
segments together to make longer cable circuits as necessary.
13-6.1.3 Low-Voltage (480 Volt) Receptacle Protective Circuit Breakers. These
low-voltage, metal-enclosed drawout type power circuit breakers are air-magnetic,
electrically operated, with 120 volt ac close, 48-volt dc trip, or 120 volt ac trip, and have
current limiting fuses. For installations utilizing MIL-C-24368 receptacles/plugs, circuit
breakers are interlocked with their associated receptacles so that the circuit breaker will
trip automatically if an attempt is made to remove the assembly plug or open the
receptacle cover and a remote close/trip of the circuit breaker is provided at the
receptacle assembly.
13-6.1.4 Shunt Interlocks. Circuits serving submarines must utilize a shunt trip
interlocking scheme. Verify that the system trips all breakers associated with the
service to the submarine at that location. Circuits serving other ships may, but are not
required to, utilize shunt interlocks.
13-6.2
High-Voltage (4,160 Volt and 15 kV) Terminations and Protective
Circuit Breakers. The system provides a 4,160 volt or 15 kV, three-phase, three-wire,
ungrounded, 60-hertz source.
