Default Wiring help?

Maybe I should call this "Wiring help for dummies?"


I have a J14 Carolina skiff. No wiring (bought used).


Questions:
1) Battery to motor - should there be a fuse inline? (I plan to add a Blue Seas on/off switch)
2) Battery to (what next? bus bar, or fuse block - should I add both? if so, in what order?)
3) I plan to use a marine grade control panel. Should I get a basic panel? or do they offer them with breakers? (thus eliminating fuse block?)


Thoughts? help?


Thanks.

answer 1, yes it would not hurt. My boat does not have one but it is highly recommended. It will protect the motor and also the wire leads.
Answer 2, depending on how you have the boat set up you can go from the battery switch to the fuse block. Now if you are running a switchboard with breakers then you can go from battery switch to distribution panel or right to the switch pannel. Its all about how u want it set up. I have seen it where the breakers are Daisychained not requiring a distribution block or like it is on my boat each breaker leads back to the distribution block for power.
Answer 3, yes they make Premade panels both with the built-in breakers or fuses .

Thanks for the prompt reply.


So if I use a control panel with breakers, I do not need bus bars (correct?)


Thanks

Hello. Yes to fuse between motor and battery, anything connected directly to a battery should have fuse, remember to connect anything that needs permanent live (bilge pumps, stereo memory etc.) should be wired before the battery switch or to the input stud on the switch, these devices should also be fused. If you have a panel, buy one with appropriate busses (negave and positive) already installed. Hope this helps.

just put a breaker if anything that way it's resetable in seconds and you won't have to keep buying fuses.

i know most boats don't have this since bigger motors and older ones require more amps at starts ups and Will over power most fuses when started killing them instantly.

Good info thank you all.


So I think I have my head wrapped around this... let me make sure I got this right...


Bilge - direct to battery with fuse inline to positive - check.


All other accessories...
Battery positive post - wire to fuse (less than 1 ft from battery) - then onto control panel with breakers - then to bus bar
Battery negative post - wire to negative bus bar.


After that, all wiring from accessories go to their respective bus bars (positive & negatives).


Am I on track?


Thanks

I don't think I've ever seen a fuse between the battery and motor, marine or otherwise, it is my understanding that having a fuse or breaker big enough not to blow every time you turn the ignition (higher then the CCA of your Battery/Motor) is impractical and not necessary. Everything else should be fused.

Quick fusing guide I googled: http://www.12voltplanet.co.uk/fuses-guide-uses.html

I have never seen a fuse installed between a battery and motor on the last 10 or so boats I have owned. Like stayed above trying to find a fuse big enough to be larger than the Amos of the battery will be an issue.

If you bilge Has a auto float then do that otherwise run through your panel,not to battery.

You Will not need the pos bus bar . the control panel switch with breaker takes care of that . all your pos ends of your electronics plug into them.
