If the engine starter initial draw is 500 amps, then as it spins is around 200 amp. It seems this breaker would work ok as it does not take that long to crank before the engine fires up? Typically, my boat engines start up in less than 5 seconds. The chart seems to be saying breaker at 200% rating of 400 amps drawn would still give 15 to 30 seconds of run time before tripping.
I would prefer a 300 amp breaker, but not finding a name brand.
Any ideas about if this could work, or a 300 amp decent breaker?
I have been thinking to breaker protect the starting battery on my boat.
