I am going to have a grand total of two 120VAC circuits in my cabin.
Sometimes powered by a generator, sometimes powered by an inverter.
I'm thinking that I can easily get by using just a transfer switch, since those have built in circuit breakers, and putting disconnects leading into the t-switch.
Thoughts?
If that was my cabin I'd use an RV transfer switch like this one from Iota Engineering. It's automatic and can be set to have a 30 second delay for the generator transfer.

I have one of those in our RV. It handles up to 30 amps, but they have larger models. The unit is $55 at http://www.solarseller.com/iota_automatic_transfer_switches__iota_power_distribution_panels__inverter_load_.htm
I also have one of their 55 amp 12 volt chargers. Very good units. Two year warranty. My units that are a few years old were also made in Arizona.
It does not have any built in breakers but solarseller also sells a number of different DC rated breakers. I also got my breakers form them. Keep in mind that for 12 VDC the Square D QO series of breakers are AC and DC rated and available at HD. DC rated up to 48 VDC.
TheSolar.biz also sells the Iota for the same price and it should be tax exempt here in NM if there's a solar panel involved someplace.
