Transfer switch from inverter to generator
I have a small off grid cabin that is powered by day with a Xantrex XPower 1500watt inverter and in the evenings by a Honda eu2000i generator. It's a simple, low power system without any service box; and up until now, I just unplugged one source and plugged in the other every evening. Now I want to put a transfer switch inside the cabin, but nothing expensive. I tried using a standard 3 way light switch as a transfer switch (that worked fine for me for years on a smaller system in another cabin), but I ended up frying the inverter. I've ordered a new inverter and done a little research, and now I'm ready to give it another try. Both the generator and the inverter put out less than 15 amps, and the cabin actually draws much less than that (just some compact florescent lights, a radio, and a laptop). Leviton makes 15 amp, dual pole, dual throw, center-off, maintained contact switch (Leviton part # 1282) that I think should do the trick, but it is not usually used for the purpose I'm considering. It's usually used to transfer a single power source to two different loads (or to reverse the direction of a motor), while I want to use it to transfer between two different power sources to a single load. The DPDT switch has six terminals--three on each side, but I'm not sure how to wire it for my purpose. I've done a fair amount of standard wiring, but this is beyond my technical ability to figure out. Can anyone tell me if I am correct in assuming that this switch will work for me; and beyond that, how to wire it. Oh yeah, the cabin's lights and outlets are wired with 14/2 Romex. Thanks in advance for any help.
