What Is The Standard Of Kitchen GFCI?
If you’re looking for the standard of kitchen GFCI, this article is right up your alley.
With our help, we can provide you with all the information that you need to know about what it takes to install a GFCI in your kitchen.
Do you know the standard of kitchen GFCI?
Kitchen outlets are often wired to provide 20 amp, 120-volt circuits to GFCI outlets. Must kitchen outlets be 20 amp? Kitchens must have at least two 20-amp outlets. These outlets are used for high voltage appliances such as microwaves, blenders, and toasters.
As you know, GFCI (Ground Fault Circuit Interrupter) is one of the most important devices in electrical circuits to protect people from shock. It can be found almost anywhere that has electricity running through it i.e. kitchen gfci breaker etc. If you are thinking about adding another GFCI breaker into your existing system, then here are some guidelines to follow before doing so
First of all, the circuit must be rated at 15 or 20 amps and should not be more than 20-amps. Secondly, there should be no other outlets on the same circuit except for shared bathroom receptacles, which cannot exceed 5-amps each at any point in time.
Thirdly, it is best if you have a GFCI breaker for any 15-amp circuit. In case you have two heavy-duty appliances on the same 20-amp circuit, then it is considered safe to use a GFCI breaker or outlet. When you need to know more about kitchen gfci, please refer to the following guidelines:
- It is best not to install any 240‑volt appliance on a shared bathroom circuit as this will increase the load considerably and possibly trip the breaker. Even if your home does not have multiple bathrooms with different circuits, it is advisable that you do not share outlets between kitchens and bathrooms as this can be very dangerous in case an electrical fault occurs. If there are no other options available but to do so, then make sure that you install at least one 20-amp breaker between kitchen and bathroom circuits.
- Make sure that the GFCI outlet is not more than 6-feet away from the water source in case there is any leakage. Even if your home does not have multiple bathrooms with different circuits, it is advisable that you do not share outlets between kitchens and bathrooms as this can be very dangerous in case an electrical fault occurs. If there are no other options available but to do so, then make sure that you install at least one 20-amp breaker between kitchen and bathroom circuits.
- It is best to check what size wire was originally installed when the circuit was created; only then will you know if you need to upgrade it or replace it entirely. It is also necessary to know what equipment runs on that circuit (including the appliances and lights) before you can use it for other purposes.
- You need to make sure that there are no switches or receptacles between the GFCI outlet and the water source because this could lead to nuisance tripping of the breaker if there is any leakage.
- Kitchen gfci should be connected properly with ground fault interrupters, which should include a control panel in order to function correctly. If not so, then you will only have half protection i.e., against electric shock but not an arc flash hazard or fires caused by faulty electrical appliances. There are specific instructions given for each type of installation, which you must follow carefully in order to avoid any mishaps. For more information, you need to contact a certified professional electrician and get your job done on time.
Apart from this, there are specific instructions given for each type of installation, which you must follow carefully in order to avoid any mishaps. Keep these points in mind when you begin your project and call an electrician if you have any doubts or questions at all.

GFCI kitchen code
GFCI kitchen codes are one of the many banes of coder life. As you can see in this picture, an outlet is being used as a GFCI.
GFCI outlets have vertical slots instead of horizontal slots like normal outlets have. There are several reasons for this that I will go into later but first let me explain why they exist at all.
The main reason is safety
Because water and electricity don’t mix well (and sometimes eat your flesh too). A standard 120v circuit could deliver enough current to melt tissue within seconds. It only takes 0.01 amps to feel tingly or give you a short little shock, but it doesn’t take much more than 1 amp (or ~125 volts) before your heart stops beating.
As long as the current stays under the threshold of 1 amp you won’t get seriously injured or killed* by electrical shock, but there are many things that could cause it to spike way over that limit.
For example, if your hand was submerged in water while being shocked you would be in serious trouble because the resistance of your body’s tissue drops dramatically when soaked with water or other liquids. This means that more electricity can flow through your body since water offers less resistance than dry skin… not good!
Another reason for GFCI outlets is something called stray voltage… this really isn’t so much an issue with course, but it is still a legitimate problem. In old buildings, the wire insulation may have started to go bad and become conductive.
This could cause stray voltage where you wouldn’t expect it. For example, say that there is a wiring fault in a wall somewhere and electricity starts running along an outside wall into your house. It might then run right through your outlets before going back into the wiring of the building… not good!
In this case, GFCI outlets would cut off power from all of your outlets whenever they detect anything between 110v-125v on any one of the hot wires feeding it.
This way even if electricity from outside runs inside, frying your computer or electrocuting you while you sleep, at least the GFCI outlets will cut power to all of your other outlets as well, stopping further damage from being done.
The last reason that I see people using GFCIs is that they don’t fully understand electricity and what can happen if you hook something up wrong.
It is true that an incorrectly wired outlet could cause a lot of problems, but there are many things that would have to be done incorrectly for it to be a problem… so I’d suggest not adding a GFCI unless you have some specific need for one.
For example, if you had an old 2 prong outlet that had only 3 wires connected to it then it could cause problems with using large power tools or vacuums because the third prong is there mostly to ground your appliance in case something goes wrong. If it isn’t grounded then you could get shocked while using these appliances and it would be very dangerous.

How to install GFCI for kitchen
GFCI stands for Ground Fault Circuit Interrupter. This is a very important tool that helps prevent electric shocks and electrocution.
It also reduces the risk of fire. A GFCI works by preventing excess current from traveling through the body of a person who may be in contact with some electrical equipment that is faulty, damaged, or has been exposed to water.
In kitchens where appliances such as refrigerators, ovens, dishwashers, etc are used it becomes necessary to install GFCIs as these appliances release some amount of current which needs to be controlled. In this article, we will discuss how to install a new GFCI outlet in your kitchen.
These instructions can be different depending on what type of breaker you have in your home but generally follow these same steps.
1) Since you are dealing with electricity, ensure that the power to the circuit is switched off at the fuse box. So go ahead and switch it off. To ensure safety wear rubber gloves while performing this or any other electrical work in your home or workplace.
2) There are two types of wiring present in most homes – one follows a horizontal pattern and is attached to the bottom of each room’s light switches, while the other is vertical and attached to all outlets, fixtures etc throughout each room. Identify which wiring layout your home follows so that you can plan your project in an efficient manner. The following images show examples of both types of wiring layouts in common use:
3) The next step is to disconnect the existing outlet. It may be necessary for you to see inside each of your wall outlets so that you can identify which one belongs to the kitchen.
To do this, use a screwdriver and remove the faceplate from your outlet by simply unscrewing it.
Once this has been done, take out the receptacle and then detach its wires by simply pulling on them using pliers or your fingers (pliers are recommended if they are stuck).
Ensure that you label all three wires before removing them – black wire goes in the “line” slot, the white wire goes in the neutral slot while bare copper wire goes in the grounding slot of the GFCI outlet.
Remember that these correspond with the same colored slots or terminals present in GFCI outlets too. If you are unsure of their function, it may be a good idea to consult an electrician at this point.
4) Now remove the existing GFCI outlet by unscrewing its screws using a screwdriver. Remember to take note of which all wires are connected whereas doing so ensures that connecting new outlets is much easier later on.

5) Once you have completed disconnecting required wires, measure the distance between your old and new box locations – this will come in handy if there are any obstructions preventing the installation of strip or junction box at the desired location (junction boxes can also be used for installation purposes). If no such problems exist then proceed to step 6 otherwise continue with step 7 before returning to step 6.
6) Setting up a junction box is no rocket science – there are very specific instructions on how it should be constructed depending on where you plan to install it in your home. Below are some examples of different types of junction boxes which can be used for this purpose:
7) If your outlet doesn’t have a grounding wire then skip this step, otherwise if the second set of wires still attached to the old GFCI outlet has a grounding wire then follow these steps.
First, identify the ground wire with green insulation present in the bundle alongside black and white wires and attach one end of the grounded wire (included with the new outlet) to its respective terminal inside the GFCI receptacle.
Now ensure that bare copper wire (used as ground wire in old outlets) is attached to the grounding screw in front of the new GFCI outlet. Remember not to attach any wire at this time and wait for step 8 first.
8) Now measure and cut a strip of non-metallic sheathed cable (NMC) so that it can be used as a substitute for permanent wiring from the switch box to the junction box. This NMC is then connected with the terminals inside the new GFCI outlet, keeping in mind that black wire goes into the “line” slot, the white wire goes into the neutral slot while green grounding wire goes into a ground slot.
Ensure all connections are tight or else you will have some serious problems later on! When cutting the length of NMC remember to take its respective box locations into consideration before cutting it – 3 ft longer would be good.
9) Now, return to the junction box and using pliers, bend both bare copper grounding wires (also attached to the old GFCI outlet back in step 5) such that they can reach the grounding screw present inside the new GFCI receptacle.
It is a good idea to leave sufficient slack in this wiring so that movement of fan or light doesn’t cause any problems later on. The final outcome should look similar to the following images:
10) After this has been done, feed one end of NMC from the switch box through the wall and connect it with GFCI’s ground wire while ensuring that you have left ample slack outside for insulation purposes before connecting the other end with neutral wire from the switch box.
After this has been done connect the other end of NMC with the junction box’s ground wire inside using a green wire nut provided in the junction box kit – this ensures that all grounding wires are connected properly so that hazards related to electrical shocks do not occur in future. If everything was executed correctly you should have something similar to the following picture:
11) Now, cut the excess length of white neutral wire present inside the switch box and strip both ends with 1/2″ of insulation. Connect one end to a white neutral screw on the bottom of the new GFCI outlet while leaving the other end for use for the next step.
Do keep in mind that the neutral terminal present at the top is for connecting 3-switch combinations only – if you don’t have any three-way switches then ignore this connection!

12) Get rid of those extra wires dangling around the junction box and screw on the new GFCI receptacle so that it is attached properly:
13) Screw three-wire cables (to be used for connecting the switch to the outlet) into the top and bottom screws present inside the GFCI receptacle. Remember that these two connections are your “line” connections – refer to the installation manual for further clarification if you have any doubts regarding this matter – now connect one end of NMC which has been fed through the wall with an upper screw while another end should be connected with “load” terminal on the bottom of new GFCI using green wire nut provided in the kit. If everything was executed correctly you should have something similar to the following picture:
14) Use wire ties to attach an excess length of NMC. Ensure that it is not touching any bare electrical wires – this would act as ground wire causing shorts at some point in the future which could result in hazards, so ensure proper insulation before tucking it back alongside other wires:
15) Screw a white cover plate on top of the GFCI outlet and you are done! Just recollect all hardware that was used for installation and store them properly. Congratulations on completing your first electrical project!
16) Remember that the following precautions should be taken while using a newly installed GFCI outlet:
Do not connect power supply wiring by attaching black wires with any bare ground or neutral (white or grey) wires inside the junction box or else it will act as ground wire resulting in hazardous conditions at some point of time.
Do not connect wiring to any screw except the one designated for ground connection – do remember that GFCI is equipped with an internal circuit breaker which trips when load connected to it draws more current than rated by UL standards.
A small test section on the bottom of the new GFCI receptacle should be kept free from metal spatial, etc. If this test section (grey in color) is obstructed then the GFCI outlet will trip automatically even when it is working fine!
All electrical devices like fans, lights, etc must be connected to properly grounded outlets if you want them to work properly without tripping circuit breakers attached to GFCIs.
If these appliances are directly plugged in without grounding their frames to the proper ground then they will act as “floating” devices drawing current out of GFCI outlets resulting in tripping circuit breakers due to false/nuisance trips.
If you have two or more three-way switches installed at a place where only one switch should be present then it would result in frequent nuisance tripping of GFCIs at that location which could prove pretty annoying after some point.
The remedy for this problem is simple – go back and check your wiring diagrams carefully to ensure that all wiring was done properly before throwing /replacing any faulty GFCIs which are acting up due to a number of reasons mentioned above.

How to calculate GFCI for kitchen equipment?
How to calculate the GFCI protection that is required for refrigerators, freezers and ice-makers? This question comes up frequently. So let’s see what the requirements are.
What is the difference between a standard circuit and a kitchen equipment circuit?
A standard electrical outlet has two conductors – one hot wire (black) and neutral (white). Standard outlets are protected by an overcurrent device in the form of either a fuse or breaker. Kitchen tools typically have three conductors -one hot wire, one neutral wire, and one “equipment grounding” conductor. The purpose of this third conductor will be discussed later in this article.
Although it may be tempting to bring power into these circuits by simply tapping into an existing circuit, this is not allowed.
These kitchen circuits must have their own individual 20-amp circuit – a dedicated circuit with its own breaker or fuse in the electrical panel.
The reason for using an individual 20-amp breaker instead of pigtailing into an existing 15- or 20-amp circuit is that these appliances draw very large currents when they startup (up to 15 times the running current) and can cause other outlets on the same branch circuit to lose power temporarily when they are turned on.
This means that any lights downstream of these outlets will dim momentarily when you turn on your freezer or refrigerator. Incidentally, if you “pigtail” one outlet onto another it is potentially dangerous because plugging in an appliance like a vacuum cleaner could cause the outlet to overload and start a fire.

What is the purpose of the equipment grounding conductor (EGC)?
The GFCI breaker or receptacle not only monitors for leakage current but also monitors for ground faults. If you plug your countertop microwave oven into an ungrounded outlet (two-prong outlet), it may trip the GFCI device when you cook something that generates large amounts of static electricity.
The solution is to either replace that two-prong outlet with a properly grounded three-prong receptacle or add some type of supplemental ground fault protection downstream of the offending appliance – in this case, by installing a separate GFCI breaker on the circuit powering your microwave. Art Inter
A word about a kitchen design:
Most custom cabinet companies still install a single 15-amp branch circuit to power all of your kitchen outlets. Although this is legal, it would be a good idea to upgrade these circuits to 20 amps in order to provide dedicated power for high draw kitchen appliances such as dishwashers and microwave ovens.
If they have been wired with standard 12-2 type NM cable, I recommend that they be upgraded from #12 wire up to #10 AWG – which you can do yourself or hire an electrician to do.

How many outlets should GFCI protected kitchen circuits have?
Kitchen countertop receptacles are required by code to be GFCI protected when installed within six feet of a sink – but only one outlet needs the protection.
This means you can either install one GFCI protected duplex receptacle or two single GFCI protected outlets. Once again, it is my opinion that two separate 20-amp circuits are best – but the choice is up to you. In our house, we have both. We have one 20-amp dedicated circuit for countertop receptacles and a second 20-amp dedicated circuit for undercabinet lights.
Kitchen code requirements:
Article 210 covers general wiring requirements in kitchens and laundry areas of residential buildings including townhouses and manufactured homes. Although the NEC only requires a maximum of six feet from a receptacle within a kitchen to a sink, NFPA 101 – The Life Safety Code requires that all 15 amp and 20 amp receptacles within six feet be GFCI protected.
This means that you must provide at least one GFCI protected duplex receptacle on all countertop surfaces and additional GFCI protected duplex receptacles must be provided underneath any kitchen or sink countertop surface where the electrical appliances are used.
Conclusion
When installing your circuit breaker, be sure to follow the National Electric Code. The NEC is a set of regulations developed by professionals for professional installers and electricians. It will help you determine what GFCI standard kitchen outlets should have installed in them so that they are safer around water sources.
