I posted once before with some concerns about my ongoing electric rewiring project on a Catalina 30.
I posted awhile back with too many basics questions. Master Chief Jackson gave me some general guidance and directions towards finding a lot of the answers to my questions. I have traveled his and others paths and sadly they lead to more questions…
Here is my plan laid out. I have numbered the steps, if you have something to offer or add…PLEASE DO SO!
AC Layout
I made a schematic of my AC needs.
I am using a Blue Sea 8027 AC Panel with a 30 amp main breaker and 3 additional 15 sub breakers.
I have a shore power connection that leads to a 30 amp main breaker about 12” from the connection.
This then goes to the panel and the panel’s 30 amp breaker.
The three15 amp breakers go to
Do I run all the green grounding wires from the outlets, the shore power and the charger to a bus bar?
If I do, where do I terminate this bus bar? Or does it just collect the grounds from the various devices and then ‘float’.
DC Layout
I made a schematic of my DC needs
I am using a Blue Sea 8023 DC Panel a Blue Sea 8697 Battery Switch Panel with a 100 amp main breaker
I am using a Blue Sea 4316 DC Panel in the cockpit for easier access to devices needed to run boat while sailing
OK HERE WE GO!
The main bank is in the nav table, the reserve bank is in the engine compartment.
I am going to run the alternator directly to the reserve bank, but set up the battery switch so that both banks can be charged when it is set to both.
Do I fuse each bank with with a 50 amp fuse before they are connected to the battery switch?
OR…
Do I have it? Did I still over think it?
No pride of ownership here. Any help or suggestions would be great! Got to have the boat off the cradle by May 22…..

Starboard outlets
The first outlet on each side is GFI

Do I fuse each bank with with a 50 amp fuse before they are connected to the battery switch?
OR…
I run the alternator to the reserve bank, but connect the ignition to the reserve bank for starting, still allowing both to be charged when the switch is set to both. If I do that, should I fuse the starting bank with a 50 amp fuse before running the line to the ignition switch?
The battery switch has a 100 amp breaker, this is wired to the 8 breaker DC panel.
I will run my various devices back to the panel.
The panel has both the ground and neutral bus bars attached.
Do I run the neutral to the neutral bus bar on the panel and the hot to the hot/breaker side?
OR
Do I create a neutral bus bar and run all the DC neutrals to that bus bar and then run one wire to the panel’s neutral bar?
I don’t see where a hot bus bar fits into the picture. It seems to me that all the devices need to be run directly to the panel on the hot side.
Each device might need it’s own smaller fuse.

Would it be better to run a line from the device to a fuse panel equipped with small 1-5 amp fuses, then from the fuse panel to the hot side of the DC panel where the breaker is, then from the neutral side of the panel to the neutral bus bar back to the neutral side of the device?
I want to run a secondary panel to the cockpit, do I run this line off the 100 amp fuse of the Battery Switch Panel?
I want to place a 50 amp fuse just prior to the secondary panel
I assume I would do the same with a neutral bus bar and separate fuse panel here too.
If I should a second fuse panel to protect each device, should I use a fuse panel with the glass tube fuses or the new ‘car type’ fuses?
