Kitchen wiring dillema

[Rosco]

I am trying to finish the wiring on the bonus room over my garage. I plan on having a full kitchen and am wondering about all of the separate runs I am doing. After reading several wiring books and code requirements I have become a little confused

So far I have 4 separate 12-2 circuits running to the kitchen (not counting lights), but think I need more. I have the following plan so far;

1 for the refrigerator
1 for the microwave
2 for the counter outlets
6-3 running to the stove

I also plan on having a dishwasher and disposal. Can I branch off of any of the above circuits for these two items or should I run another feed from the main panel. I have a 200 amp main in the garage on its own meter so room in the box is not an issue. I am just trying to keep the attic runs to a minimum. If there is any risk of overload then running another wire or two is not a problem, just looking for some advice.........

I would take another run up for the dishwasher/disposal.

the kit counter ckts can't be used for any thing else.dish washer and disp should be on thier own 20 amp ckt's.some places let you get by with dish washer disposel on same ckt.you will need six ckts in kit unless dw/gd can be on same ckt then you need 5.all 20 amp.

I would not run a separate for the microwave unless it's a built in with hood. Counter top units use almost no power anymore. Other than that, what oleguy said - figger about 6. I put the DW and GD on the same circuit. FWIW - When I go through the kitchen, I'm pulling a line from the main box to a sub panel above the kitchen. Saves some wire IMHO.

Thanks for the replies. The microwave will be a built in with fan. I will probably run the DW and GD off of the same since I will not be using either that often. I do not plan on installing a GD, just running the power for future use. Dont like using the GD at all in my house since I am on septic.

Then again, what would be the harm in one more string of 12-2.........

decisions.....decisions.......

Maybe you could put a subpanel in the kitchen area, then you wouldn't have to run all those circuits from the main panel? One longer run of a larger wire vs. many runs of smaller wire.

All of the above appliances except for the garburator MUST be on their own dedicated circuits,two counter recepacles are permitted to be on one circuit.The GD usually is put on a general circuit,as they are used intermittently and not all that often.Your local rules may vary,the CEC and NEC are very similiar when it comes to residential kitchens.

That is a great idea except I already have 4 of them run........wish I would have posted earlier

in the US you have to have two circuts for countertop receptacles (small appliance branch circuit its called)

Also true in Canada,I should have phrased it better.However,it is permissible to have two receptacles on each circuit,but you must have the minimum of two circuits,and the ones adjacent to the sink must be GFCI protected..

I will have the two circuits for 4 total countertop outlets..........seems kind of excessive but code is code and inspectors are inspectors. I am just damn glad that I decided to put in a 200 amp panel with its own meter after all of the wiring in the garage and then the bonus room!

That is one great thing about reading this site. The best advice repeated over and over........"its never gonna be big enough" and "always plan for future needs or expansion"

Thanks again!

Here are the requirements from Art. 210 for GCFI requirements...


(A) Dwelling Units. All 125-volt, single-phase, 15- and
20-ampere receptacles installed in the locations specified in
(1) through (8) shall have ground-fault circuit-interrupter
protection for personnel.
(1) Bathrooms
(2) Garages, and also accessory buildings that have a floor
located at or below grade level not intended as habitable
rooms and limited to storage areas, work areas,
and areas of similar use
(3) Outdoors
Exception to (3): Receptacles that are not readily accessible
and are supplied by a dedicated branch circuit for
electric snow-melting or deicing equipment shall be permitted
to be installed in accordance with 426.28.
(4) Crawl spaces — at or below grade level
(5) Unfinished basements — for purposes of this section,
unfinished basements are defined as portions or areas of
the basement not intended as habitable rooms and limited
to storage areas, work areas, and the like
Exception to (5): A receptacle supplying only a permanently
installed fire alarm or burglar alarm system shall
not be required to have ground-fault circuit-interrupter
protection.
FPN: See 760.41(B) and 760.121(B) for power supply
requirements for fire alarm systems.
Receptacles installed under the exception to
210.8(A)(5) shall not be considered as meeting the

This is a copy and paste from the 2008 NEC.

The DW & disposal can be on 15A circuits, I prefer 20A but both are fine.
