I posted a related question a week or so ago, but the thread got diverted somewhat from my original question, so I'm starting a new thread here. I'm attempting to use a 15 amp DPDT switch as a transfer switch between my Honda EU2000i generator and my Xantrex X-Power 1500 inverter to power my off-grid cabin. The generator and inverter also power several other buildings, but I'm only interested in using the transfer switch on the lines to the cabin which never draws more than 350 watts.
I've bought a Levitron 1282, 15 amp, DPDT switch which is usually used to switch a single power source between two different loads (or to power a motor between forward and reverse). What I want to do is to wire it so that it switches my cabin (the load) between two different sources (my inverter and my generator). I got a pretty clear answer from cariboocoot, but since actually getting the switch, I'm confused anew. First off, the wiring diagram for the 1282 on Levitron's website does not show the terminals in the same configuration as the diagram that came with the switch--and, to top it off, the terminals on the actual switch itself are labeled differently than either of Levitron's own diagrams!
Before proceeding, I want to be sure that cariboocoot's suggestion is correct. It sounded perfectly logical to me, but the conflicting information from Levitron is confusing me. I have tested the switch in it's two "on" positions (it also has an "off" position in the center) to determine where there is continuity, and I have attached some drawings to this post. The first one is the switch with the terminals as they are marked on the switch itself, and I have indicated where the continuity is in each position. The second and third drawings are of the conflicting wiring diagrams (which I didn't intend to follow anyway) that have come from Levitron. If cariboocoot or anyone else can help clarify my predicament, I would be most appreciative.
A few other points. The Honda does not have any neutral-ground connection and neither does the inverter. The generator is not grounded, but the inverter is. There is no kind of box at the entry point to the cabin, but I'd also appreciate advice on where to install fuses. Of course the generator and inverter have internal circuit breakers, but it seems prudent to add some fuses when I put in the transfer switch.
Thanks in advance for any suggestions.
