Automatic Power Off Circuit Diagram | CircuitsTune For example this auto power off circuit can be used with garden porch light, soldering iron glue gun or similar other devices to auto shut it off for saving electricity or save the device, or you can use it to suit your own needs. Generator Auto Start and Auto Stop | All About Circuits All i want is to make it a standby power source (witch require a electric circuit to do things). now this circuit will have couple of functions. when main power supply fails (220 v AC) it will start generator (2 to 3 tries) and when the generator stabilizes (approximately 10 sec) shift the load to generator and when the main supply restores it shut off the generator and put back the load to ... How can I shut off circuits when I have a generator with ... As far as the generator goes, it should have a on auto off switch on it. Turn it to off, and then it won't kick on. On the matter of a breaker not turning off the power to that circuit, that sounds wrong to me, and I would have them back out to correct that, as that is not a correct installation.
