I got a call from a homeowner who had a plumber install a disposal under her kitchen sink, but there's no wiring under there to connect it to. Directly under the kitchen, the basement is completely finished all the way back to the recessed panelboard, which was full. I pulled out the dishwasher and found it hardwired with a length of 14-2 NM; I think it's on an individual branch circuit.
My idea was to reroute the 14-2 to the interior of the cabinet under the kitchen sink, where I'll put it in a box and feed a split-wired receptacle: unswitched hot for the dishwasher and a switch loop for the disposal. I generally like to put the dishwasher and disposal on separate circuits, but in this case that's not really an option. 210.23(A)(2) seems to be the relevant section, and as far as I can tell, having both of these appliances on one 15A circuit would still be legal. My take is that the 50 percent rule only applies when there is lighting or cord-and-plug equipment not fastened in place.
