I want to use
this data logger (which I have already purchased) to record start/stop times for my standby generator. In the generator ATS, I have a wire connected to one of the gen's "hot lug" and another to the neutral bus. I have 120vac present at the two wires during weekly exercise cycles and when running on generator power.
I wanted to use a regular enclosed relay like
this one, but the guy at Grainger said it would oxidize quickly and fail because there won't be any current going thru the load side of the relay, since the data logger senses resistance (open or closed).
So are there relay types or other devices that will better handle what I have? For an idea of the duty cycle it will be in, under normal conditions, the generator runs once for 15 minutes per week for its exercise cycle. Power outages can range from minutes to days (hurricane country).
Thanks,
Ira
