Yet another Kitchen Sub-panel Post...Sorry
 
I did look back to other sub-panel posts, but wanted to post what I think I know, and ask a stupid question or two. My apologies in advance to everybody who has answered these things so often in the past!

I have 200 Amp main panel in the attic, which will be a finished space in the future. There are 8 unused spaces left on it.

I am renovating a kitchen on the ground floor, on the opposite side of the house from the panel. Rather than run the 8 circuits my kitchen needs all the way back to the main panel, my plan is to install a sub-panel for kitchen and future needs in the attic, directly above the kitchen, so I only need to run wiring straight up to the sub-panel. I have a code-acceptable location up there, in terms of clearances, so that is not an issue.

The kitchen circuits are, I think, as follows:

Slide-in range: 250V-50Amp dedicated circuit...6/3NM
Dishwasher: 125V-15 Amp dedicated circuit...14/2 w/ ground
Garbage Disposal: 15 Amp dedicated....14/2 w/ ground
Microwave: 125V-20 Amp dedicated....12/2 w/ ground
Refrigerator: 120V-20Amp dedicated....12/2
Small Appliance: TWO 125V-20Amp GFCI dedicated...12/2 w/ground
Lighting: 125V-15Amp...14/2

Questions:

Should dishwasher and garbage disposal be bumped up to 20Amp?
Is the sub-panel strategy an efficient/economical one?
How large a sub-panel would be required/prudent? (I assume it should not just be dedicated to kitchen circuits, so possible future expansion is possible)

Thanks in advance.

I would also like to add a couple circuits for new patio lighting and perhaps a water feature pump. Still hoping a 60 amp sub panel would work. Comments regarding this and above post?

Thanks in advance!

A good starting point would be to look at the nameplates on each of the major appliances you'll be using; range, dishwasher, garbage disposal, microwave. Each should list an amperage or wattage with which you can do a rough load calculation to see how much power you will need.

You are hoping to run a 60 amp subpanel and have it feed a 50 amp stove? You would be better off to run the stove to the main panel.

id run slightly bigger than 60 amps, but not much is needed. Everyone runs 50 amps to a range, but have you ever stuck a meter on one? Mine draws something like 10 amps.


still id do a little bit more. Something like #2 aluminum with a 90 amp breaker
