Two 20 amps GFCI outlets used for kitchen back splash


Is this properly connected or need to be changed? Note: Bare ground wire connected to both A and B metal boxes and to green screws on outlets A and B

Wired used from main Panel to both A and B outlet is 12awg/3 with ground, Red, Black, white and bare ground.

From main panel to 1st Outlet A, cut the red wire in the box and connected the end side of the wire from main panel side to Brass screw on line side of outlet, the other end of the red wire capped and taped inside box, the remaining red wire between box A and box B is now (Dead wire.) White wire cut in box A and connected one end on the silver screw line side of outlet and the other end connected in the hole behind outlet on same line side, (Instead of Pig Tail wire) Is this good not to use pig tail this wire section continues to outlet B and connected on silver screw on line side and now the Black wire connected on brass screw line side and the red end wire also capped and taped in Box B. In Main Panel I used a...

I think I've got it. The circuit breaker says 20 on it. The plugs in living room & kitchen are 15 amp. The breaker, not the GFI determines max cumlative load. If I want a 20amp outlet in that spot then put in 20 amp GFI. If 15amp outlet will do (i.e. don't have need for single appliance > 15amp) then 15amp GFI plug is fine.

A key I was missing, is that the 15amp GFI passes through the 20 amp current so it's the breaker that determines max load.

If later someone does need plug in a 20 amp appliance, they'll have to upgrade the GFI as well as any other outlet where they want to plug it in.

Thanks!! Especially to the first few folks.

Some of you didn't really read my question. (For instance, I said in my ques that code is not US specific but local.) Though sometimes every bit of data is helpful even if not specifically on target, so thanks for adding...

If you are planning for a kitchen remodel, big trends tend to take the drivers seat for design and planning. When planning big picture design, electrical outlets should be carefully planned & placed with thought and purpose.

Your kitchen is an electrical outlet hub that has various needs for different tasks. From major appliances to small appliances, to lighting, exhaust fans & built-in appliances, each has their own space restrictions and needs that need to be thoughtfully planned out. A place to charge and store your phone or tablet might be a high priority, or perhaps a small electric hub that holds your coffee pot, juicer & blender is a must.

Between electric codes, aesthetics, placement and more, we are here to help break down your questions and concerns to create a perfectly groomed space that meets all of your electrical needs.

Frequently Asked Questions about How to Wire a Kitchen

Kitchen Counter Outlets and Back Splashes

Counter Top Back Splash Outlets

Question from Dan:

I have installed the rough wiring for a kitchen, and at the back of what will be the counter top. I estimate will be approximately 2-3 inches clearance I'll have at the base of the outlet box to the top of the counter top. Does code allow for a In back splash outlet? What should I do to extend the wall up more or what?
Dave's Reply:
Dan, the back splash could be treated the same as if it were tile, so installing outlets there should be ok. It would not be ideal because it would require cutting into the back splash, but it would work. You will need to be very careful to plan the location of the outlets and keeping in mind the height of the counter top and the depth of the back splash. A box extension may be required after the back splash is in place. Also make sure the wires will extend 6...

Electrical code basics and recommended practices for kitchen renovation often seem like pointless rules cooked up in an office boardroom.

And while electrical code eventually does get hammered out across conference tables, most of it originates from people who work in the field: electricians, contractors, and other industry professionals. These recommendations influence the U.S. National Fire Protection Association (NFPA).

This is the group that writes the National Electrical Code (NEC), which then is adopted in whole or part (or not adopted) by your municipality.

So it is more than about making your local inspector happy. Far from draconian, the code actually addresses only the bare minimum. The NFPA updates the code every 3 years to meet the increasing requirements of the modern kitchen. Are you current with code?

The circuit breakers in the electrical panel in your house are safety devices. Each one is designed to disconnect power when the current passing through the circuit exceeds its rating. This prevents overheated wires, electrical power surges and fires. Electrical outlets don't draw power until you plug something in, so a 20-amp circuit should theoretically be able to handle as many outlets as you want without overloading the breaker. There are practical limits, though.

Allowable Breaker Load

The National Electrical Code doesn't limit the number of receptacles you can place on a 20-amp circuit, but you'll overload the breaker if you run appliances that draw more current than the breaker can handle. The NEC does specify that a circuit breaker shouldn't handle more than 80 percent of the load for which it is rated unless the breaker is labeled otherwise. By this standard, the total current draw on a 20-amp circuit shouldn't exceed 16 amps. This allows the breaker to...

Before beginning to wire your outlet, you will need to decide whether it is to protect any "downstream" outlets that may have been installed previously.

Any electrical circuit begins at the panel box, goes to the first device or outlet and from there to others. Those that are electrically further away from the panel are termed "downstream" and can be protected from ground faults by any GFCI outlet that is "upstream" from them.

The first step is to turn off the power and, if possible, test it with a voltmeter or a non-contact voltage detector.

If you don't want to protect downstream outlets (maybe it's a freezer outlet) then all the wires in the box will need to be spliced together with a "pigtail" to the outlet. Splice all the black wires together, including a 6 inch piece (of the same wire size!), all the white wires the same way and lastly all the bare, ground, wires. Use the 6" piece to terminate on the outlet.

The outlet will actually have two sets...

We tracked down an electrician who, not surprisingly, adds kitchen outlets all the time. He showed us how he adds an outlet to a kitchen backsplash by running conduit through the back of the cabinets. This method is fast, inexpensive, super simple, and best of all, doesn’t require a whole bunch of wall repairs or painting. This article shows how to install one new outlet, but you can add several by following similar steps.

Step 1: Before you get started

Kitchens need to be on a dedicated 20-amp circuit and require 12-gauge wire. Today, 12-gauge wire is wrapped in a yellow sheath, but your old cable may be white. New circuits in kitchens need both arc fault and ground fault circuit interruption (AFCI, GFCI) protection. In this story, we’re adding an outlet to a kitchen that already has GFCI protection, which has been required for many years. If your kitchen is not on a 20-amp circuit, or doesn’t have GFCI protection, you’ll have to install a new circuit...

Guide to Wiring Outlet Circuits
Electrical Question: How many receptacles can you wire onto a 20amp circuit breaker?

This electrical wiring question came from:
David, a Handyman from Millmont, Pennsylvania.

Dave’s Reply:
Thanks for your electrical wiring question David.

The Number of Electric Outlets on a Circuit

Application: Wiring Receptacle Outlets.

It might help to remember that the Code and commercial components were designed to take faults into account. For example, an approved 15 amp receptacle MUST be designed to carry enough current to trip the 20 amp breaker without self destructing. The reason this is possible is because it is designed to carry 15 amps 'forever'. A fault condition is a short term thing and wires and metals can carry currents much higher in these conditions; they don't have time to degrade before the trip occurs.

As an obscure example, there is a place in the code which specifically allow 12 gauge wire (normally thought to be good for 20 amps) to carry 50 amps during a trip condition (tapping rule, table 210.24). Note that 12 gauge wire is not ALWAYs ok for a load of 20 amps; it must be derated in many situations.

A familiar form of this is a typical lighting fixture. I believe you can actually have 18 gauge wire connected to a 20 amp branch circuit depending on the lights...

We are just beginning to start with our kitchen remodel. Today, I mapped out all the circuits and this is what I found.

Circuit # 7 - 20 amp circuit to 1 back splash outlet then to 3 kitchen wall outlets, then to a closet outlet and closet ceiling light and then to a side porch light!

Circuit # 8 - 20 amp to Dishwasher and Disposal

Circuit # 9 - 20 amp circuit to microwave and kitchen ceiling lights. 2 patio recessed lights and dining room ceiling light.

Circuit # 12 - 20 amp circuit to another back splash outlet then to 2 dining room wall outlets.

Circuit # 14 - 20 amp to Refrigerator only

Circuit # 18 - 15 amp to GFCI outlet in garage then that feeds 3 outlets for 3 bathroom outlets and 1 outside patio outlet.

I going to have to add 1 more back splash outlet due to increase in counter space. I'll put the microwave on a dedicated circuit. So I need 2 additional breakers but I only have 1 blank spot in the breaker panel. I guess...

First I would buy a circuit tester for about $5.00. Make sure it is the one with the red button on top that will test GFCI outlets. Make sure you have a proper ground and that the test button trips the outlets properly. Test them all and they all should break the GFCI the same and have the proper ground and polarity.If this is ok I would direct my attention toward the appliance. Could try as an test, bringing the coffee maker to your bathroom to see if it trips that outlet as well. could help confirm if it is the coffee maker or the outlet.
Then I would see what the plug rating is. Is it 15 or 20 amps. You will tell by the one side of the outlet having a cross or a t in it. Then check the size of the wire to see what it is. Lastly the breaker. You should have a balanced circuit, or eveything rated the same or better than the breaker.
Could be that the fridge or the dishwasher is on the same circuit, thus tripping the GFCI before the breaker. Small...

Split Circuit Outlet


Read the legal disclaimer page - click the legal link in the menu above

Split circuit outlets have been used in kitchen counter areas for use with small appliances. Codes have evolved over the years and there is some variations on codes between Canada and the United States or even between jurisdictional locations. Since I am not working in the field I want to be able to provide information about split circuits but yet refer you to our expects I have lined up in our forums for verification and specific requirements where you live.

Kitchens tend to have a number of higher amperage appliances so you don't want to use the rule of thumb which would be 8 per 20A circuit. One typical trick would be a separate 20A circuit for things like microwaves or toaster ovens and then stagger several circuits along back-splash areas so you can easily reach a separate circuit if you have a number of appliances in the same area. You should always have separate circuits for major appliances like refrigerators and dish washers.

According to the National Electrical Code book (NEC) each receptacle is calculated at 180 VA. A 20A circuit at 120V would be 2400 VA. Divide 2400 VA by 180 VA = 13.33 receptacles per 20a circuit (13 receptacles), but the above poster is correct in saying that the more circuits in a kitchen the better. The NEC requires at least two small appliance branch circuits in a...
