Re: locking batt switch enclosure
After some obsessive overthinking I have come to the conclusion that making the enclosure myself is going to be the way to go. In fact, when I put all the components together that are going into this "electrical gear locker" I realized that it is going to take a rather large subpanel. I have all the components already: Three batt switches+ cabling, Xantrex auto combiner, 4 bank auto charger/maintainer, two 12v main feed breakers, and all the wire and cable.
Currently all the electrical systems gear is located under the floor hatches in the cockpit area. (accessible? yes if you like lifting heavy hatches all the time) In 1968 ABYC electrical standards did not exist and my boat was a perfect example of that. I went through a complete rewire over a years period and added all the stuff listed above. I have learned two things; one, the 1-2-both switch I used is confusing when using an automatic combiner, and two, its a real pain lifting those hatches all the time. System diagram below:
Note: dc panel located in cabin, diagram does not include 4 bank charger. Manual combine switch provided in case of auto combine failure. Individual battery switches provided total independent isolation.
Below you can see the inside of the cockpit area.
