Terminals, plugs, switches, and seals covered by this specification are intended for use with the casualty power system on Naval ships. These items are part of the casualty power interconnect system that is installed on board ship to provide temporary transmission of power to span damaged areas.

(a) Upper and lower riser terminal (for use with cable type LSTSGU-75 in accordance with MIL-C-24643/16). Used to provide transmission of power between decks.

(b) Back-connected terminal (for use with interconnecting wire, size AWG 2 in accordance with MIL-W-16878/8). Used to provide transmission of power through nonwatertight bulkheads and from switchboards or equipment enclosures.

(c) Bulkhead terminal, watertight (for use with two back-connected terminals and seals, and interconnecting wire size AWG 2 in accordance with MIL-W-16878/8). Used to provide transmission of power through watertight bulkheads. The bulkhead terminal installation consists of two back connected terminals and two rubber seals in accordance with MIL-T-24552/3 to prevent water leakage through the bulkhead without the aid of mated plugs or covers. Bulkhead terminal is mounted as shown on figure 3.

(d) Switches are used with connectorized cable type THOF-42 in accordance with MIL-C-915/6. The cables provide a means of supplying and interrupting power to loads that may require intermittent power from the casualty power system.

(e) Plugs are used with the terminals and switches and are furnished unterminated. When completely assembled, the plugs form part of the THOF-42 cable assembly.
