Any suggestions on wiring the dishwasher and disposal on the same 20 amp circuit under the sink? I have heard that it is ideal to put a switch in the sink cabinet independently controlling the dishwasher and disposal. If this is true, I need a suggestion for getting the wire (BX cable) to come out of the wall, into the switch, and back again to the receptacle. Your thoughts are valued. I have the kitchen ripped out, and have freedom to put together as best suggested. Also, is GFCI needed here? Thanks.
