Hi,
I'm diagnosing a pair of three way circuits that we found to be odd, because its operation started tripping a gfci. I had another look at it, and it appears that there are two sets of hots from two different breakers. In other words, the upstairs pair of three ways are fed via the gfci I mentioned, while the downstairs switches have another 120v source. I don't quite understand it.
What led me on to it is that one of the switches operates a light fixture, while the other operates an outlet. The outlet still has 56V on it when switched "off". Further, some legs seem to show 35V when switched in certain configurations. I've been reading about carter and California type three ways, but I'm not sure this is it. I'm trying to diagram it but even that's tough given the number of conductors. Any recommendations on how to deal with this??
Thanks!
