Did the subs (WWII vintage) have circuit breakers?  

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.
