I'm in the process of tearing up the kitchen and just mapped out the
current wiring. I'm doing a complete remodel and am moving just about
everything around. I currently have the following circuits and plans:

Circuit 1: 240V 30A (currently not used - gas range)

Plan to move outlet behind new range location just in case it is needed
in the future. Will splice in basement so no buried connections.

Circuit 2: 120V 20A
Currently: Refrigerator, gas range, range hood.
Plan moves gas stove to other wall, so will probably just be the
refrigerator and a counter outlet. Will add GFCI even though not
directly by water (about 9' across from sink)

Circuit 3: 120V 20A
Currently: Dishwasher, two counter outlets, switched light over sink,
two living room outlets.
Plan to remove the dishwasher and add GFCI and a couple more outlets on
the counter for convienience. Will also have micro/hood, gas range and
will probably tap in some additional lighting (not more than 250 Watts
or so).

Circuit 4: 120V 20A
Currently: Disposal on switched outlet.
Will move to a switched outlet at the new sink location.

I will add a new circuit for the dishwasher. Do I need to make this a
20 amp or is 15 sufficient? Will put in an outlet behind the
dishwasher location for convenience.

I was also thinking it might be good to extend a couple outlets off
circuit 2 to the new counter outlets. That way I won't trip the
breaker if someone decides to run the microwave, can opener, blender,
toaster, and whatever other appliance at the same time.

I've got 100Amp service in a new panel that was just installed this
summer when they found the old one full of water while wiring the new
AC.

All appliance will be brand new, so that should cut down some energy
use there too.

Anything I am missing?
