I received a great birthday present this year - my 60th by the way. My wife conspired with my son-in-law to find out what charger converter and control panel I had been looking into buying from Best Converters. Thanks to Randy at BC they were able to figure out that I was looking at the Xantrex XADC P30 fuse panel and the XADC 6012 Converter. So I am finally able to spend some time hooking things up. Here are the specific products that I have:
XADC 60A Converter/Charger
XADC 30A Distribution Center
The overall unit is very compact and nice looking. I am not constrained by the previous interior since my unit was mostly gutted. I do intend to put it near the front door since that is where the original converter was located. I do like the idea of having it be more accessible that the original one was too.
I find in studying the DC wiring diagram in my service manual and looking at the existing fuse panel that I have some unresolved questions relative to the new hook up. My unit was largely gutted when I bought it so some of the orignal hookup was not there for me to look at either. After careful review of the diagram and the old fuse panel I drew up the wiring diagram that is in the attached PDF file. I believe that it accurately shows what is in my wiring diagram with the exception that I have added the Xantrex components where they logically seem to go. So here are some issues and questions that I have at the moment:
1.) Do I really need the 50amp fuses on the negative side of the components? Somehow it seems to me that I should be able to just tie all the ground connections directly together without any fuses. Were they perhaps there to protect from wrong polarity hookups?
2.) When I installed 3 new Fantastic fans I decided to wire them up on their own circuit. I intend to connect them to their own 20amp DC fuse in the new Xantrex panel since I have room for more fuses than before. I can't imagine why that would be a problem but please let me know if you can think of a reason.
3.) Notice that I have a factory installed Propane powered DC generator. I don't know how much I will actually use it but I would like to at least have it hooked up correctly. The way it hooks to the so called "Main and Charge Circuit" has me wondering how the voltage level that it puts out will be regulated. I suppose that the connection to the control panel is for the purpose of monitoring voltage level but I don't know for sure. Any thoughts on this?
4.) The two fuses to the right of the converter in my diagram were originally glass fuses on the actual fuse board. I am wondering what to replace them with since there doesn't seem to be anything in my Xantrex panel that fulfills this function. I could visualize using a 50amp resetable circuit breaker like the following:
RV PARTS OUTLET
This particular product is also available in 20amp and 30amp sizes but does not seem to be available in a 40amp version. Do I still need these two fuses in the arrangement that they are in? What kind should I use?
5.) I have not yet gone hunting for the 25amp fuse shown near the tow vehicle connector. Is that still needed? What type should I expect to find and what type would be best to have there?
6.) Wouldn't it be better for me to install a new sound system on its own fuse rather than connecting it to the Main and Charging Circuit?
7.) There wasn't any battery disconnect switch in the original design. How important is that? Should I consider adding one?
Thanks in advance for any help. I will try to take some good photos of the process and can also publish a new wiring diagram once I figure out what it should look like.
