Ok, I'm reading through Jeff Volp's stuff on x10, phases and couplers. Need a little clarification.
I understand a split-phase. Meaning I have 3 wires coming in to my house. 2 "hot" leads and 1 "neutral".
In my panel the incoming neutral goes to the white neutral bar for all white neutrals. The 2 hot leads go to the main breaker and feed one each side of the column of breakers. So 1 hot lead feeding the odd numbered breakers and the other hot lead feeds the even breakers. That's the 2 different phases. I now understand that.
In Jeff's documents, he talks about a 240v appliance, such as a dryer, becoming a coupler. I assume that can't happen if the 240v circuit is being driven by a double pole breaker on the same phase. Such as a breaker using slots 1 and 3. Wouldn't the circuit need to come from both phases to work. Say a single pole on each slot 1 and slot 2? I've never seen a 240v circuit wired this way which is why I'm asking so I make sure I understand correctly.
