Adding fuse panel question

[redneck joe]

Have a boat that has no fuse panel so I'm adding one. I've always had one so if a fuse blew i could conveniently look at the blown one and replace accordingly. Since i don't have that luxury, how do i determine correct amp to use?

I currently have fish finder, bilge, livewell, bow/stern light and a couple usb power points.

Assuming all your wiring is 18 gauge or larger. Bilge wire should be 16 or 14 gauge

Bilge & Livewells 15 amp (draws 8)
Horn 10 amp (draws 6)
Lights 5 amp for LED
Fish finder 5 amp
USB 3 amp

I went with Carling circuit breakers. $3 each from Grainger. Add the little sealed plastic covers for $1.

Thanks. The wire on the switch matched the leads off the new pump so should be good there. Using 8 ga as the lead from batter y to panel.

you will be fine with 8 gauge wire.

the bluesea systems amp to length ratio chart is linked below

Most standard outboard control harnesses only run 14 gauge to the dash. some run 16 gauge.

With no more then your going to have, 8 gauge is great but 10 would be more then enough, but just my opinion

I bought 8 for the trolling motor extension so its 'free' wire. And yes bought the good stuff.

I got a 30 amp breaker for the electic motor.
