I'm trying, unsuccessfully, to figure out the logic my electrical contractor used during the wiring rough-in for the kitchen.

He used 14-3 cable to bring power to a double-gang j-box; the red and black conductors are each connected to a separate 15-amp breaker at the service panel. One breaker is marked for the disposer.

From this j-box, he ran 14-3 cable to the dedicated disposer outlet. The black conductor is hot. Was there a special purpose for using 3-conductor cable at this location? If so, what should the box dressing look like?

Thanks in advance for any and all advice.

He probably did you a big favor. That 3rd wire can be used to power you dishwasher. It is a multiwire circuit. The white neutral is shared between the black and red wires.

What type of disposal? Is there a wall switch or is it a batch feed?

Thanks, everyone, for your replies. The j-box I refered to is intended for the disposer switch. My dishwasher circuit is wired separately. This means that I still can't understand why the disposer outlet is wired with 3-conductor cable. It could be for a split outlet, with one side switched. Or, perhaps the electrician was simply using a convenient piece of cable.
