I have two 30 amp circuits that I currently have two 30 amp timers that power my Christmas decorations....for some reason one of the timers runs faster than the other so they do not turn on and off in unison. I would like to run one of the timers to power a contractor or relay to turn the decorations on an off at the same time. Can some one tell me how to wire this project. Plus what do I need to purchase? Thanks in advance for your advice....
