Kitchen Circuits

Hambone

Is there a limit on the number of outlets in a kitchen on a circuil for normal backsplash outlets? I think codes says there must be at least 2 circuits for the kitchen area (outlets and refrig I believe), but I can't find anything yet on how many backsplash outlets can be on a circuit. I generally use the rule of thumb of 8-10 on a non-kitchen circuit - but haven't done many kitchen additions so want to make sure. Thanks for helping me be lazy today

You didn't state the code you use so I will assume IRC.

To answer your question, "Is there a limit....?"

Yes, there is a limit.

Your other assumption about the two circuits, one receptacles and one refrig is wrong. There are a whole bunch of rules about electric in kitchens. You really need to read the rule book on this one.

Thanks Thom - I realize there are bunch of rules, but at this time I am only concerned with Outlets in the backsplash. Hopefully someone can answer ... back to reading the code (NEC 2005) for now.

The IRC and the NEC are mute on the number of receptacles along the kitchen countertop. Different under the CEC, if you happen to be up there.

thom

Once again you are correct MD. We have some very specific requirements. They are local (state) additions.

Hambone

I think I found what I needed in 210.52 ... Receptacles installed in a kitchen to serve countertop surfaces shall be supplied by not fewer than two small-appliance branch circuits.

So you are correct that the number of outlets on a given branch is silent, but at least 2 circuits are required. I will check local requirements as I have heard that only 2 outlets are allowed on a branch. Problem with this remodel is the kitchen is huge and will require around 16 outlets - so that might be 8 seperate branch circuits depending on local code requirements.

Two, 20 AMP small appliance branch circuits for the kitchen countertop receptacles is the bare minimum. As is the entire NEC for that matter. You say this is a big kitchen. Why do it on the cheap? Perhaps you can run 3, or 4 circuits to the countertop and avoid any possible overloads after the walls are closed up. I would also suggest separate 20 AMP circuits for the microwave, refridgerator, and any other neat things that demand alot of current. You will most likely need a few ckts for a dishwasher and garbage disposal too. Also, some of the new vent hoods require their own separate 20 AMP circuit as well.

Good luck!

FWIW, the (2) required circuits count as 1500 watts each when it comes to calculated loads.

And, check for local additions to your code. Our additions include:

Max 4 recepts per circuit
Min 2 circuits
Countertop recept circuits may not extend elsewhere
Dedicated circuit for dishwasher/disposal
Dedicated circuit for microwave (if built in)
Dedicated circuit for any other built-ins (compactor,???)
Refrig on another circuit (not kitchen stuff), I just do dedicated
Lights may not be run off circuits listed above.

Every counter top needs a GFI . no more than 2 ft apart. IRC E3801.4.1

mdshunk

You'd better read that again. That's not what it says at all

Tom M

No point on the counter is more than 24" in any horizontal direction from a receptacle or 4' apart. With exceptions for corner sinks and ranges. Hows that MD?

mdshunk

Thanks for clearing that up. Now the earth can return to its normal axis.

There is no limit to number of outlets, only common sense. But 2 small appliance circuits are required......

Just remember that kitchens use a lot of power . And that 2 circuit minimum rule is based on the smallest kithchen around.

Hambone

Thanks everyone for the posts. This is a large kitchen and I am working with the electrician on how many circuits. We'll get it right - I don't like skimping on electrical outlets and its much easier/cheaper to add more circuits now than once this is finished up.

Appreciate all the looks and posts.

Magnettica

Thats correct. The rule is similiar to the habitable room requirement but instead of every 12', it's every 4'.

And instead of a receptacle needed at every wall space more than 24", for a kitchen countertop the rule is 12".

That's the best way to remember the rule, IMHO.

That was a very simplified way to remember something Mag

Ham,
I'd get the client involved, too...

I oncegave all my builtins proper circuit & split two to each side of a kinda smaller kitchen and was called back in for tripping breakers...
Client dumped ALL their plug in stuff at one place AND proceeded to use it all at once.

I was very lucky... buildup and also service were right below.

Solution is 2 outlets per circuit for the kitchen. Local code mandates it and I think it is reasonable given the potential load of appliances and I want to be sure I don't have tripped breakers
