Question

organizing kitchen circuitry


1. three recess lights
2. recess microwave with fan
3. small (18-inch) dishwasher
4. garbage disposal
5. 2 regular double 15A outlets
6. gas cooktop (which still, i believe, needs some power supply for the clock)
7. fridge

i doubt i can dump it all in a single 15A circuit. how should i divide and conquer ?

thanks,

You will need 2 20 amp circuits as a min. for the kitchen.
1 20 amp circuit to split between the dishwasher and the disposal.
The gas cooktop can feed from one of the 20 amp circuits.
When I wire a kitchen, the fridge is on a single circuit, as well as the microwave.
The lights can be wired from another lighting circuit from another room.

i would expect that there would be some sort of a calculator online that gives you the optimal layout of circuits if you crank in all the outlets by amperage and location.

why the heck would a gas cooktop need 20 amps ???

Kitchens are required by code to have 2 20 amp small appliance branch circuits.
Unless prohibited by local code, dishwashers and disposals share a circuit. The fridge and cooktop can be run from one of the 2 20 amp circuits. The microwave should be on its own circuit, or may be required to be on its own circuit, depending on size.

I am telling you what code requires. How you wire it up is up to you and the inspector!

He isn't saying the range needs 20 amps, he is saying that you can power the range off of one of the two required 20 amp small appliance branch circuits.
By code, you can't power anything else off of these small appliance branch circuits, except for a fridge, and a stove and a clock.

SEE: Do I need a new box?

Are you doing this by code or not?

Dishwasher and disposal could be on the same 20 amp circuit. I believe there is some discussion about this. I put mine on the same circuit but this is a good time to run a 12/3 wire and do a multi wire branch circuit.



I've never seen 15 amp GFIs but apparently they exist. But if you can't get your hand on a 15 amp GFI outlet, then your outlets will need to be 20 because they do need to be GFCI. Is your kitchen so small that you really only need 2 outlets?

Ok I did not know you were not in the US/Canada in which case I really can't comment on requirements.

ROFLMAO - i am in washington DC - english basement is a style, not a geographic reference, much like a french door

OK Sorry. You should find out what code they follow if you are getting a permit. If not, then use good judgment.

1) Lights on a separate circuit or existing lighting circuit
2) Microwave on dedicated 20 amp circuit
3/4) Dishwasher/disposal shared on dedicated 20amp, or each their own 15 or 20 (seems to be discussion on this suggesting shared on 20amp isn't acceptable but I can't figure out why not - this is how mine is)
5) Kitchen outlets have to be GFCI. You do not see 15amp GFCI very often (or at least I don't) so they are most likely going to be 20 amp. You need to have at least 2 separate small appliance branch circuits, even if you only have 2 outlets. In short, off the top of my head, every piece of counter space needs to be within 24" of an outlet, but you can stop when you go around the sink.

6/7) Cook top, fridge, and a clock are the only things that can be tapped off of your small appliance branch circuits. I have heard people recommend not to go off of the small appliance branch circuits due to GFI tripping and spoiling your food.


These are off of the top of my head and rough requirements and your requirements could be entirely different - see your lcoal code requirements.

5) Kitchen outlets have to be GFCI. Either 15 or 20. I don't see any reason to run this as a 15 amp unless your wiring dictates that.

6/7) GAS Cook top, fridge, and a clock are the only things that can be tapped off of your small appliance branch circuits. I have heard people recommend not to go off of the small appliance branch circuits due to GFI tripping and spoiling your food. I have one 20amp circuit that goes to the fridge first, and one GFI outlet loads off of that. Not sure if that is code acceptable or not (it's how the house was when I got it).
