You have to spend more money to get breakers that have a 5000 AIC rating. ANL's are 6000 AIC, MRBF's are 10,000 AIC and Class T fuses are 20,000 AIC rated.
The breaker came from Lewmar with the H3 windlass so I hope it is up for the task. No specs came with it. I will call Lewmar to verify the 5000 AIC rating. My bad on explaining the breaker directly to battery, there will be a fuse within 7" of the battery.
As far a charging I have decided to use an echo charger from the house bank.
The alternator goes to the house bank so I figure the windlass battery will always get a charge. The start battery can only be charged by using the crosssover switch at the moment. Since the house batteries are within 5' of the start battery would an ACR make more sense than another echo charger off the house to the start? Does the start battery really need 30 amps that the ACR can supply or would the 15 amps from the echo do the trick?
