redmexican5081 Posted January 25, 2019 Posted January 25, 2019 I've decided to replace the wiring on my new to me boat. I got marine grade wiring, a master switch and a main fuse. I am having some indecision about how to wire up the console. The wiring I plan on removing all comes direct from the battery with inline fuses to each powered item. The battery has about 8 wires coming off the positive terminal and I know I can do a cleaner install. I am thinking it should go battery->main fuse->master switch>-fuse panel->dash switches->item needing power for lights, bilge, etc. but I am unsure about the order of fuses vs switches. I think fuses then switches on the chance a switch ever gets a ground short but am I correct? Quote
Mjmj Posted January 26, 2019 Posted January 26, 2019 Your order is correct. Battery Fuse Shut off switch Fuse panel Switches I ran mine in a similar fashion but added a bus bar: Battery Main shutoff Fuse Buss bar Fuse panel Switches Let me know if this helps. 2 Quote
Arcs&sparks Posted January 26, 2019 Posted January 26, 2019 @Mjmj what are you using the bus bar for if you used a fuse panel? Multiple fuse panels? The main over-current protection should be as close to the source as practical. Then the main switch. Redmexican, your order is correct. You can also use negative bus bars in locations where there is a lot of wiring, and run a single oversized conductor back to your panel or battery if you please. If your our boat is aluminum do not use chassis ground like a trailer or vehicle-but do bond the chassis off of the (-) battery. Quote

The bus bar is for 2 fuse panels ( I have a bunch of electronics at the bow) and 2 auto deploy anchors. I have all these items enclosed in an 8x8 waterproof electrical box, with the main shut off on top of the box, for easy access. I did tell him his order is correct. 2 Quote
