Why do homeowners insist on doing it the least practical way? Is it to impress their neighbors and friends? I dunno.
This dope needs to run 12-3 NM and jump out with 12-2 to another box. Also, be sure to splice the neutral through so it doesn't accidentially send 160 volts to the microwave and 50 volts to a coffee maker. This prevents the "unbalanced" load in the neutral wire from ruining your kitchen appliances.
