GE Zenith ZTX automatic transfer switch (100 amp, 60 HZ)
Model: ZX1SM01021-21
Built 2003 (as you can see from the photos; it was built in Sept 2003 and installed in Oct 2003).
This automatic transfer switch was part of a backup electrical system (with a very large, permanently installed Honda generator outside the house) that was installed by the prior owner of my current home (which I purchased just a few months ago). The system was fully functional but I did not (and do not) need it, so I am selling it all. (The Honda generator is already gone.). I do not know more about the system and its features other than what the photos show/tell and what you can find online. I had the transfer switch removed by a certified electrician, who told me the unit was working fine. This transfer switch had been mounted in the basement, right next to the main breaker box (controlling the house's electrical distribution). It was tough to get my phone in the small opening to take interior photos, but I tried my best.
