Rewiring a boat

I plan on doing this electrical project this winter. The thing is over the years a lot electronics and lighting have been added to my boat and I want to get away from my old fuse panel (witch is almost impossible to get to easily) and add this breaker panel. <br /><br /> http://www.seatechproducts.com/index.php?id=17&cat=67&prod=578 <br /><br />I have a total of 12 circuits so this one works for me but I also have a shore power connection to consider. As this panel does not offer this feature I'm adding a seperate panel for my shore power (there is currently no panel at all). I only have three outlets and don't want to spend a fortune on this as I rarely use shore power.<br /><br />Anyhow, I know I need tinned wire. I plan to use crimp style connectors then solder the connectins prior to applying the heat shrink insulation. I have considered all of the wattage issues and the only circuit I will have multiple connections to is in my lighting. I have 4 courtesy lights, 1 in the cabin, one at the helm and 2 in the cockpit. I don't think all these lights would need more that a 10 amp breaker. The other concern is two 30A outlets. One is for the cig. lighter and the other will go in the cabin for DC/ coffepot, etc. Is 10ga. wire enough for each circuit on these connections?<br /><br />The last issue is to be sure all the negative wiring is up to snuff. I am planning on replacing my bonding wire with a 8ga. (currently 10ga.) wire from the neg. connection (at eng.) to the fuel tank, then to a negative buss under the dash area where my fuse buss is now connected. I also plan on running a 8ga. wire to my arch. did I miss anything? If anyone has any advice to offer I would appreciate any comments.

Re: Rewiring a boat

I can do any boats wiring or fuel system to USCG req. But I would NEVER try a complete system without being there to check as you go along. You are going to have to find some one local, so you don't burn or blow up something. Too many chances for a bad bo bo to happen.

Re: Rewiring a boat

Your plan sounds do-able. At least you have a PLAN!!! The wire sizes and connections, the circuits sound ok. I would use an anti-oxident grease on all the connections. I use it on every connection on the boat and have no problems.<br /> I would also run all the wires in some knd of conduit. All my wires run in flexable plastic conduit, it keeps the wires neat and prevents them from being mashed. Clamp them in the bundle to a convienent spot along the route. If you have fish finders run them seperate. ;) <br /><br />lee

Re: Rewiring a boat

I wouldn't call this a complete rewire. I'm just replacing fused buss with a Breaker Panel.<br />My fishfinder trans. cables run alone away from any other wiring on the starboard gunnel. Everything else runs along the port gunnel. The new breaker panel will be installed near where the old fuse buss is now (aprox 2 feet away) except it will be accessable and not under the dash. I have two locations in mind. One is below the shift/throttle assembly comparment which offers easy routing and plenty or room for the panel and wiring. The other location is just behind this area at the gunnel adjacent to this location. I'll try to get a pic up for before & after pics.

This would not be difficult at all and your plan sounds good to me. Don´t forget a master c/b near battery to protect stuff downstream. <br /><br />Locate the panel in the most sheltered, accessible location available. Did my boat last summer and it was both an enjoyable and easy project.

Re: Rewiring a boat

I just got through reading where the bonding system and ground should be two seperate systems. Perhaps more reading before I undertake this "enjoyable" project. I think I'll check out a few books at the library and do more research.<br /> I have a 60A fused connection between the house batteries and the start batt right now. This is what was recommeded by BEP when I installed this switch last year. <br /> http://www.bepmarine.com/showcategory.cfm?categoryid=4
