I'm installing a refrigerator into my Hunter 28.5. As with projects of this nature, I opened a can of worms. Adding the refrigerator draw into my energy consumption calculations - guess what - I need new, larger A/Hr batteries. Yeehaa!
I'm not putting $580.00 dollars worth of batteries into the boat and then charge them off of a NAPA plug-in car charger. Maine Sail has a thread regarding battery selector switches. I found it once looking for something else, but it stuck with me. Attached are two pictures, the first is a photograph I found in the thread, and the second it a block diagram I drew to understand better what Maine Sail had written and showed in the photograph.
I would like to make sure I my understanding is correct. Some question though:
- The Blue Seas fuse holders I found come with 6 ga leads. The longest positive run is 6 ft at the most. Is 6 ga large enough? What amperage fuses should I be using?
- In the photograph is shown a "From Batt Switch Feed". Is this from the common terminal on the selector switch?
- Is the shunt necessary, if so, what is recommended?
- Ship ground. I'm not sure where this would go other than the common ground at the engine block.
- I'm planning on using knife style SPST battery disconnects, is this a good choice?
I thank you in advance for all advice and corrections,
Alec
