I own/live in a brownstone (build in 1900) apartment (split off in ... 1960's?) that's been worked on by many clueless DIY or incompetent electricians so I'm slowly but surely untangling (pardon the pun) the mess that's here. I'm about to replace all the cabinets in my kitchen and it seems like a good opportunity to correct many terrible mysteries that lie there.
While taking inventory of the number of circuits that run to the kitchen now, I came across something of a puzzle. There is a 12/3 armored cable that comes out of the wall that was direct wired into a dishwasher that was here (that I got rid of) and there was 12ga black and neutral, and ground wires coming out of the cable. However, on the panel, that conduit has 12ga black, red and neutral going into it. The circuit breaker that the red is connected to does not seem to control/effect anything.
Is there a way that I can track down where the red hot wire ... uh ... leaves the conduit? It's certainly possible that the conduit goes through some junction box along the way and we will be opening the walls behind the cabinets when they are removed, but for planning purposes it would be helpful to know now whether the hot red wire is somewhere in the kitchen or not.
In case it helps, here are some pictures:
