I have just purchased a '67 Cal 28 flushdeck and am starting to refurbish it.
I have already modified my priority list to move electrical wiring (and rewiring) to the top. This is the first sailboat I have owned and I am not the handiest man around (my sailing experience is 25-30 years ago and primarily I was ballast).
I have read the forums here and at a few other sites and scoured 2 electrical marine books for knowledge (so you know I have tried!).
My first project is adding shore power and wiring 110V AC into her. I have a healthy respect for 110V and therefore am using a certified contractor to do the actual wiring but I wish to minimize the cost by insuring I am purchasing the proper components and that my ideas are sound (at least in theory).
I am installing the power inlet (30 Amp 125 Volt Power Inlet Stainless Steel | Marinco
) inside of the cockpit and the breaker box directly behind (within 2 feet). The breaker I have chosen is a Blue Sea 30 Amp main with 4 15 amp wired breakers (BLUE SEA AC MAIN + 6 POSITIONS 3412
) as I am planning on the following distribution:
A) battery charger (sole)
B) refrigerator (sole)
C) microwave (sole)
D) cabin plugs to include lights/computer/stereo amp (shared)
Each of the A, B,C and the first of the D circuits will have GFCI outlets (West Marine: GFCI Duplex Outlet Product Display
) and we are using stranded. tinned marine wire.
My questions are as follows:
1) Is there any reason to have metering on the distribution panel or is non-metered sufficient?
2) Grounding - as I have no inboard (a blessing as I have more storage space and no Atomic 4 to rebuild) AND as I am not planning to pull her out of the water until Thanksgiving to clean and paint the hull (and add a grounding plate), any recommendations on grounding? (We have a couple including a zinc strip down the inside).
3) AND this is a major question - am I correct in keeping 12V DC and 120 V AC panels separate? I have sufficient space and an old existing 12V panel (which I will need to rewire as project #2).
Thanks to any and all who read and comment. I will post pictures of current and refurbished as I do the work.
