I have a different kind of electrical problem

Are you using 2 sets of sensors? the set in the picture and a second set clamped on the generator feed?

I'm using a 3rd sensor for the generator...since it's a 120v generator...only need 1 for it.


OK it just looked like the mechanical interlock was forcing a 2 pole breaker off (the feed from the generator) when the main was on.
