Kitchen Wiring Plan

Ok here is my kitchen wiring plan. You experts can tear it to shreds. My only question is does the disposer have to be on its own circuit? The way I have it on the same line as the fridge there should be enough slack to take the startup load. Just realized I show the DW as a plugin, but I think it's hard wired.



2 countertop receptacle circuits servicing 4 counter spaces (one receptacle per space)
Circuit # 1) 20A Countertop GFCI Duplex receptacle, Countertop GFCI Duplex receptacle
2) 20A Countertop GFCI Duplex receptacle, Countertop GFCI Fourplex receptacle(surface mount) I know I used the symbol for a duplex.

Dishwasher on its own circuit
3) 20A Dishwasher 9A

4) 20A Gas Range Est. 3.3A, Microwave/Vent 12.5A

5) 20A Refrigerator 6.5A, Garbage Disposer 10 A

 

Since the dishwasher and disposal are close together we run a 14/3 cable and split wire a duplex receptacle under the sink. Each will be on their own circuit (must install a 2 pole 15 amp breaker) and 15 amps is plenty. Most disposers installed today are cord connected. Otherwise you are required to install a disconnect. I would put the fridge on its own 15 amp circuit if you have the space.

 

I agree with TI. I would be the microwave hood on its own circuit. The instructions will call for the dedicated circuit. The gas stove can be on one of the 20 amp small appliance circuits.

 

NEC sets minimum requirements. I'd try to have a dedicated circuit for each appliance and avoid ganging where possible.

 

I actually have 8 free slots in the panel. Here is the revised plan. I figured I could get away with putting the range and a countertop duplex receptacle on the same circuit.

 

I suggest keeping 2 spaces open in your panel for future circuits. That way you can easily add a sub panel breaker without moving anything. I would do it like you had before but with the dishwasher and disposal on their own, and the range on with the fridge.

1) small appliance 12/2
2) small appliance 12/2
3) dishwasher 14/2 (or 14/3 with disposal)
4) microwave 12/2
5) disposal 14/2 (or 14/3 with dishwasher)
6) fridge/range 14/2 or 12/2 (Your call)

 

A dedicated circuit for a gas range is a waste of breaker space and material. Add it to the countertop 20 amp circuit.

 

It is not dedicated. It is with the fridge. Two small loads.

 

I did not see that in the diagram.

 

Sorry, Not in the diagram. Just in my post suggestion.
Sorry for any confusion.

 

I'd agree with Tolyn that for a kitchen that small, you only need/want two 20A countertop circuits. In your drawing, you currently have 3. Of course, it doesn't hurt if you want to run the wiring.

Don't forget about a lighting circuit. It looks like you have undercabinet lights planned, as well as I hope overhead/recessed lights. Per NEC, they can be on another lighting circuit that may already exist, but be sure it's not already close to the max.
