->  TW>  True. As an Example we started the Submarine Battery charge at 
->  TW> 5000 Amps, waited the the temperature corerected voltage to rose to 
->  TW> the proper point and then held that Voltage until the Charging 
->  TW> current dropped to 500 Amps.   :-)   :-)  :-)

-> Did the subs (WWII vintage) have circuit breakers?  

No they disn't. In fact we lost a Sub in the 40's in the North alantic
when a Interlock failed in the Main Motor Controller and hooked up the
Two Battery wells Plus to Minus. The Huge surge of power between the
Battery wells, possabibly as high as 250,000 Amps, caused termendious
releases of Hydrogen and battery well explosions.
That caused a Field Change and they installed Circuit Breakers in the
Battery wells set at 50,000 Amps. 
But on the Molten Copper we Electrictians caused that when we tried to
get fancy and change the controller sticks too fast 
I molten Copper Fireball would come out of the front of the Controller
Cage and roll down the deck plates in the After Engine room.

-> Many Sub motors were salvaged and used on drilling rigs in the 1950's to run
-> the rotary table, might still use them.

-> I used to service the AC generators on several rigs, and they were located on
-> the lower deck right behind a bank of five BIG V-12 Caterpillar engines that
-> ran the 550VDC generator for the submarine engine on the platform.  What I
-> didn't know at first was that the DC breaker panel was right beside MY engines.
->  

-> One trip out there for routine maintenance, the drill pipe got stuck and
-> tripped the breakers.  The driller said he was pulling 15,000 Amps at the time,
-> and when those breakers blew, WHEW!  I learned what "incoming
round" sounded
-> like BEFORE I ever got in the Army!  The whole engine deck shuddered and was
-> showered with glowing copper beads bouncing all over the place!  What a BANG!


->      Good luck...  M.
