I lived in a house that had the strangest wiring plan ever, so there are a few stories to tell, but this story is about two outlets on one wall, maybe six or seven feet apart. We had some very pretty sconces (with switches) that we wanted hung on either side of the window, with a simple line up the wall from each outlet. I flipped the breaker, knew it was off, and went to work. Got the first one wired in and started disassembling the other outlet and discovered in the painful way that it was NOT on the same breaker!
Who builds houses like that?
