I'm not sure the legality of this, but couldn't you take the 5v and signal from each PWM, and then have a common ground between three and hook that up to the breaker?
Also, doesn't that seem rather unnessacary? Most likely your controller and electrical panel should be near each other so it seems easier to just use PWMs rather than convert two PWMs to Cat5, then convert them back. It makes sense for something like the camera & servos, but overall it seems easier to just use PWMs.
