Electricals

 Time to run some wires. 

When designing the wiring run, I considered the following:

1) I did not want wires visual in the cabin area.
2) The wiring harness needed to include power for the following: DC power outlets, cabin lights, Nav lights, stereo speaker, GPS/Fishfinder power and transducer, bilge pump and future solar power and motor charging wires.

I split the wiring into two conduits that run from BH2 under the floorboards to the junction boxes. The conduits run through the enclosed buoyancy area under the cockpit foot well. The conduits are sealed with silicon where they pass through BH's to ensure the buoyancy chamber is airtight. A further conduit was installed athwartships to link the two junction boxes. 

I made the junction boxes from 6mm ply. They are fully sealed units with clear Perspex fronts and screwed to the transom.

 

The wiring runs up into the port and starboard aft seat back storage areas and then forward through conduits to the main cabin.

To reduce voltage drop for DC power and the main earth connection I used larger diam wires (4.5mm diam) from BH2 through to the junction boxes in the lazarettes. The larger wires continued forward to the cabin area. As the cabin and Nav lights are all LEDS I reduced the wiring from the lazarette area to the forward cabin area to 2mm diam.

All wiring was twin core tinned marine grade and to reduce doubling up of negative wiring I only ran positives for the Cabin and Nav lights. I also ran nylon pull chords with the wiring harness so I could pull through any future wiring.
