Manual on/ Auto off generator switch


Such a thing exist? Some day, soon even (maybe), I'll be installing an older onan 6.5kw generator as a back up at a place in the desert. I'd like to have to manually start it because there's not always someone there and no sense burning fuel up when it's not needed. But if it's my better half there, I'd like it to auto shut off when power is restored. So you don't have to remember.

Manual on/ Auto off generator switch


EASY STUFF !
Wire a relay across the stop button,
Using the normally open contacts,
Hook the coil of the relay up to a wall wart.

So when power returns, wall wart turns relay on,
Relay shuts down genny via stop switch.

Eary stuff !

Manual on/ Auto off generator switch


Thank you. That may be my only option. But I also realize I didn't articulate my question properly. I'm looking for an auto transfer switch that won't transfer to generator until I'm ready for it too, then auto switch back to utility and shut the generator off once power is restored. Is that available? I'm thinking it may well be too expensive if it is. But thought I'd ask.

I would imagine that most auto transfer switchs would switch over
straight away at loss of power.

But maybe there are optional settings,
but I would also imagine that it would be at extra cost.

Well, I saw a switch that is manual start and will auto transfer to utility power when restored, but you have to still shut off genny. If I incorporate your suggestion some how, genny would shut off. Wired to line side of auto switch perhaps.

The generators I am familiar with have an auto/off/manual switch. Leave the switch off until there is a power failure. Upon failure, switch to auto. The generator and transfer switch will then activate. Gen unit shuts off upon return of power. However, the exercise mode of the gen will not operate when the switch is off.

Go over to onan forum on http://www.smokstak.com/forum/forumdisplay.php?f=1 That's all these old farts do.
You can have a warm up period or cool down period or what ever you want just depends on what you want to spend. Asco is a good one to look into.

Thanks. I've poked around there before for something else. Looks like the right place to go for my needs.
