Of course you could always use the relay to run a relay. Use 24vdc in 
the SiteMonitor (or whatever voltage you have) to activate/deactivate 
the relay inline with the sensor.

and achieve the same thing. There should be very little if any current 
on those two wires since they're just used for voltage and frequency 
sensing.


I know that our 22kw QS has the 2-wire remote start option, which I 
didn't really bother looking into since we're using the normal switch 
setup.


But me personally, I will be keeping AC away from the SiteMonitor 
because some dipshit (me) will electrocute himself.

What I want to do is trick the utility power sensor in a standby 
generator so I can make it start when I want it to. So an NC relay 
in-line with that sensor, and I'll open it to make the genny start.

Yes.

Yes, as long as you don't exceed the current rating of the contacts.

Yes. You can do this.

Just look at the ratings of the relay in question.
