Battery Fusing how and how big?

[Tropigal]

Hi Y'all
Just Bought a 1978 Pearson 35 and am in the process of refitting her. One of the items brought up by the surveyor was in regard to no fuse on the battery cables. I've got 3 banks. On the House batteries I was going to install a breaker for 100 amps, wire size is appropriate, load should be covered. But on the starter battery....I'm not sure. Often the wire size is less than the instantaneous load of a starter. Any suggestions? Any one have a clue what a westerbeke 30 diesel will call for on startup?

Thanks,
Bill n Kay

Harris has some great info on wiring in the projects section of this site check it out . If what you need isn't covered there I would suggest the 12 volt bible by Miner Brotherton. or
Boatowners Illustrated handbook of wiring by Charlie Wing.
Without knowing your specific problem any advice would be guessing and that has no place in your electrical system.
good luck
Roscoe

Hi Roscoe and thanks for the note,

I guess just straight forward, do you have a fuse link or breaker on any of your batteries? Tropigal has none, this worried the surveyor and frankly worries me. If you do have a fuse on batteries let me know what size, style and maybe where one purchases the device.

Thanks,
Bill

I have a 100 amp breaker between my house bank and the breaker panel. All accessories are on the panel and use a 15 or 30 amp breaker. The engine has no fuse or breaker between the battery and hot lead on the starter solenoid.Everything running from this connection such as the alternator, instruments,
etc is fused by in line fuses
My house bank is 440 Ah and the cranking battery is 80 amp

Roscoe,
Thank you!! That was how I thought I should do it as well. I do have breaker/switches on the panel for the equipment. I'm going to install a 100 amp breaker on the "house battery" for safety.
As for this sight, y'all are a God send. I pour over it regularly. At some point I might even have something to add, but for now I'm just soaking it up.

Thanks again Sir,
Bill
