Shore Power Relocation From Port side to Stern 1989 searey 390 express

[daddy d]

I am relocating the shore power from the port side to the stern for convience, I planed on using split bolt mechanical copper connectors to splice the exigsting 10 gauge tinned wire to the new tinned stranded 10 gauge wire & insulating it correctly. then leaving the connections behind the upholster pannel, securing the cable to prevent vibration.
Any Thouths, opinions, on my choice of splicing the wire ????????
Thanks Daddy D

Do you have to splice the wires? I know marine grade cable is not cheap, but simply buying enough wire to go from the shore power connector to the panel would be the best solution.

If you are going to splice, there is no reason why you can't put it in a plastic electrical box. A box with cable clamps will provide strain relief on the connections. If you go this route you probably can use (proper sized) solder-less butt connectors with shrink tubing insulation.

I wouldn't use butt splices.

If split bolts are good enough to bring the power service into your house, then I'm sure they are up to the task of extending your shore power.

Except your house doesn't bounce around, vibrate and traverse the earth at 20 knots.

And not trying to sound like a nit picker, marine butt splices are an acceptable Marine repair.

The rest of the bolts on my boat don't vibrate loose.

I'm not nit picking either. If you use the proper butt splice with the proper crimper, you are not likely to have a problem. I've butt spliced 650kcmil wires in industrial distribution panels, butt I had the right stuff.


A butt splice relies on two points of contact and compression. The butt splice itself carries the current.


A split bolt maintains one point of connection, and the current is passed directly from one conductor to another. It is essentially just a fastener to hold the two wires in contact, and is not relied upon for current carrying capacity.


It's kind of a non issue with this small of an application. Either one will serve the purpose if implemented properly.

Why does he need any splices?

The panel on a 390EC is very near the shore power entrance and he is going to have to buy enough wire to get from the shore power entrance to the new location anyway. If I were doing it, I would abandon the present shore power entrance and go from the main panel all the way to the new location with new wire and avoid the risk of any splice method.

Thanks for opinion;s I ordered additional cable to wire direct

One point, I believe that the boat building assoc., whatever thier name is, requires that there be a fuse within the first 5' ? where the power enter's the boat. Ypo would not want 15'-20' of unfused wiring running in the boat.
