    Default electrical plan for Kitchen remodel

    Doing a kitchen remodel. I am going to rewire the room with new circuits from my main 200 amp panel. Currently the kitchen is on some shared circuits that I would like to clean up. I am looking for some advise on the layout.

    Here is what I will have in the kitchen as far as electrical….
    Appliances
    Fridge 15 OR 20 Ampere, 115 Volts, 60 Hertz (1/second).
    Full Gas range 15 Ampere, 120 Volts, 60 Hertz (1/second).
    Dishwasher 15 OR 20 Ampere, 120 Volts, 60 Hertz (1/second).
    Small Microwave Small countertop microwave

    Counter outlets 6 – 8
    5 recessed lights
    Under the counter lights
    Garbage disposal

    I have the ability to run homeruns from the main box. What would be the ideal configuration? I am more concerned about the appliances.

    Here is what I think. Feel free to rip it apart..

    New circuit for the Fridge
    New circuit from the Dishwasher and Stove
    New Circuit for counter receptacles and garbage disposal GFCI
    New Circuit for all lights.

    If you think this is overkill or underkill I would love to hear your comments.

    This is what I tend to do,

    fridge, 15amp dedicated
    Dishwasher & garbage disposal, 20a dedicated receptacle under sink
    TWO- 20amp circuits for the kitchen counter receptacles (per code)
    15 amp circuit for lighting.

    Why would you install a 20 amp circuit to the disposal and dishwasher?
    Most that I have installed call for a max 15 amp circuit in the installation book.

    I just finished up a complete gut and remodel and figured while it was all apart I may as well rewire everything. I went ahead and ran 20a circuits to everything since cost is not a huge difference and who knows what the future may bring eh? I ran seperate circuits for my fridge, dishwasher, microwave. Then two more circuits for outlets and another for lights. Overkill? Maybe but I won't have to worry about future upgrades. Btw, 12-2 is a pain in the ass

    There are a lot of energy "hogs" in a kitchen!

    Might want to think about counter-top appliances as well. Things like a convection oven, deep fryer, hot plate, etc.

    Look at the wattage on all these things and you will see how they can quickly add up! Then plug in a vacuum while these are on and pop goes the breaker!

    It seems to me there are NEVER enough outlets in the kitchen for all the counter-top appliances.

    Whenever I get around to remodeling my kitchen, I'm going to to install a subpanel nearby and plenty of fourplex outlets along the countertop, each on its own 20 amp breaker. Then of course the dedicated circuits for refrigerator, dishwasher, microwave, etc.

    To find the amperage used for an appliance, go to the following link and enter the voltage and wattage, then it will give you the amperage. (Don't forget that vacuum!)

    Use the "Convert Watts to Amps" calculator under "Single Phase"...

    Countertop outlets. I was just reading something that states that kitchen counter outlets have to be on 2 circuits. Is this true? and if so Why?

    I know that they have to be GFCIed if near water.

    Yes, you need at least 2 circuits for recepticles dedicated in a kitchen...a single item like a toaster or microwave could nearly tap one out, and how often do you have more than one thing working? The code also specifies how far apart (max) they can be. I think it's 4', but don't quote me. If you notice, most things like toasters, electric frying pans, etc., only have short cords, so you don't want to have the outlets too far apart or you may not be able to use it where you want.

    Then, most major appliances specify a dedicated circuit, or at least recommend it.

    So I am going to have 4 outlets total. 2 on one counter (Sink side) and 2 on the other. Can I set it up so each counter is its own circuit? or Should I mix it? I would not expect to use 2 plug in appliances on the same side at the same time.

    Which is more correct?

    Why not splurge and have 4 separate 20 amp circuits?

    And each outlet a 4-plex!

    That may not be enough outlets...the code is fairly specific about how far apart they can be.

    It all depends on what the size and rating is of each appliance. That is what determines what you need to run.

    There are a lot of appliances out there to choose from.

    This is an extreemly small kitchen. No outlet will be more than 4 feet apart. I only have 6 open slots in my pannel. So I can not run 4 circuits for the counter outlets. So I guess I will run one 20A circuit per side.

    If it is a small kitchen, then you are less likely to have a lot of counter top power hog appliances sitting around (and using them all at the same time) like bread maker, deep fryer, hot plate, toaster oven, etc.

    So two circuits should be plenty.

    I am surprised the Dishwasher does not need to be GFCI. Here are the reqs
    ------
    Electrical Requirements
    • This appliance must be supplied with 120V, 60 Hz., and
    connected to an individual properly grounded branch
    circuit, protected by a 15 or 20 ampere circuit breaker
    or time delay fuse.
    • Wiring must be 2-wire with ground and rated for
    75°C (176°F).


    Grounding Instructions—Cable Direct
    This appliance must be connected to a grounded metal,
    permanent wiring system, or an equipment grounding
    conductor must be run with the circuit conductors and
    be connected to the equipment grounding terminal or
    lead on the appliance.

    _______

    I figured since it involves water this should be on a GFCI circuit?

    When I did my kitchen I ran 4 20 amp circuits with 3 recepticles on each. Not all of them are near water so I did not have to use GFCIs on all of them. I decided to use GFCIs on them all because water gets all over a kitchen espically when my wife goes nuts cleaning the coutners.

    I ran a dedicated 20 amp line to the gas range and fridge. I also ran 14/3 to under the sink, one circuit for the disposal and one for the DW. Both manuals said 15 amp circuit MAX.

    I put the lights and vent hood on a 15 amp circuit.

    Now when my wife is making a holiday meal she can crank up the fryer, hot plates, blender, and mixer all at once and no tripped breakers. The best part is the fridge no longer dims the lights when it kicks on. This house was quite under wired.
