complaints when using a hughes autoformer
I am looking at a used hughes autoformer. I know some parks rules say they are not allowed. Some parks we have been in, I have seen voltage at @ 102 to 104 with my a/c on. I would be using a PI 3o...

And you do realize all TRC Surge Guard EMS units have always used 102 vac as the low voltage disconnect threshold? :W Clearly those who designed these units are comfortable with this value, just as Progressive designers are obviously comfortable with having chosen 104 vac as their low voltage disconnect threshold. ;) Since I'm not a design engineer I am personally comfortable with those who are having made this decision for me. ;)
Kind of scary as the standard design voltage is typically 120v +-10%, so below 108v starts getting sketchy.
Doesn't mean the air/con is going to burn out the first time you see 102v but it's certainly not good for it.
Also, where is you surge guard mounted? If it's at the pedestal, you can easily have 50-60' of line with further voltage drop. Even the built in ones an have another 20' from the device to the air/con unit.
Obviously, better than nothing but the 102 is likely a compromise between it cutting out every time the voltage drops for a couple seconds below 108v.
