Electrical gurus please help.  I am trying to piece together a system to
improve the trouble-prone glow plug circuitry on my diesel Vanagons.  I need
to build a circuit that will carry 50 amps DC for 15 seconds at a time.  Can
anyone point me to a circuit breaker that will provide 50A for the required
time, but trip if the power is not switched off?  I prefer to have one that
will reset itself after is has been tripped and cooled down.  I have found
plenty of sources for manual reset breakers.  Heck, even my '53 Chevy has
breakers (30A) that reset themselves!
  For the diesel fans in this crowd, the controller works correctly, but
this is the second time I have had a total meltdown in the stock wiring due
to what I think is excessive current for the plastic controller socket.  The
first time it breaks, I fix it.  Second time, I replace it!
