Thanks all. Sounds like I need to stick with the recommended 3 amp protection. This would rule
out circuit breakers unless I can find one smaller than the 5 amp one, which cost 3 or 4 dollars, BTW.
Actually, the more important reason suggested to me supporting a breaker was that if the motor got hot from having to run continuously and blew the fuse,if I'm not around, the fuse won't be replaced. Had it been a breaker, it would automatically reset after cooling
, and could continue pumping. Perhaps it doesn't work
this way, and perhaps these automatic reset breakers aren't for marine
use to begin with.
This is not the typical scenario for a boat, but the amperage recommendation is certainly valid. I'll make sure I keep it at 3 amps, either way.
