 TM 55-1905-220-14-1
d. Several of the ship's circuits use direct current power (See Figure 1-48). The direct current power comes from a
regulated dc power supply rectifier. The rectifier gets its power from the 120-volt distribution panel. There are two
rectifier output circuits. One is for charging of the 24-volt standby batteries. A second circuit supplies a fused distribution
panel (P-24). The standby batteries may be used to supply the fused distribution panel when ship service power is dead.
e. When shore power is available, connection to the ship is made at the shore power connection box located outside
and aft of the deck-house. The shore power connection box is connected to the main switchboard. It is then connected
to the 450-volt distribution panel and distributed through the normal network system.
f. Ground detector lights are located in the generator main switchboard in the Engine Access Aoom for the 450-volt
distribution system, and in the 120-volt distribution panel for the 120-volt system. Detection of a ground in the system
calls for qualified personnel for correction.
