Our new wire and cable came in
The white 10/3 is for the water heater 110 and 12 volt connection
As you can see the red 2/0 is for the nav-station panel to battery bank. It replaces the old original cable.
We have it set up behind the nave station but have not connected the cable to the batteries yet as we did not want to tear apart the boat on a work night.
We will get rid of the low loop to the left when we hook it up.
