what size circuit breaker

[fishykivette]

What size main circuit breaker should I use on my accessory battery? I plan to have a bilge pump, livewell pump, two courtesy lights, a main deck light, nav lights, horn and a in dash stereo with 4 speakers. I have drawn a schematic for this project but didn't know what size main circuit breaker i should install.

By the way I have a fuse panel and all component a have a designated fuse. I was also wondering what size i would need for my starting battery. Thanks

I don't know if I would use one breaker for everything. I usually fuse componets with seperate fuses or breakers, that way you don't loose every thing if a component shorts out.


You shouldn't need a breaker or fuse for your engine, there should be a fuse in the engine harness.
