What Size Gfci Outlet For Bathroom?
Many people think that a GFCI is only necessary for the kitchen and outdoor outlets. This couldn’t be further from the truth. In fact, there are many bathrooms where you’re likely to find a GFCI outlet; these include bathrooms with tubs or showers, and kitchens within the bathroom (like in a bathtub).

There are many rules for how many outlets you need in a bathroom. The minimum requirement is one GFCI-protected receptacle served by a 20-amp circuit, but most bathrooms have at least two or more.
What is a GFCI (Ground Fault Circuit Interrupter)?
It’s a device that breaks an electrical circuit when the current to ground differs by more than 4mA (0.004A) from the current in the “line” wire. It has one common and one hot terminal, and a third, isolated grounding terminal.
How to use GFCI?
When you test a GFCI receptacle, you will probably see two buttons: One with “Test” and one with “Reset.”
First, press the button with “Test,” then touch one probe of a multimeter to the ground terminal and the other probe to each of the other terminals. If it’s working properly, no current will flow in either direction through any wire. You should get a reading close to zero on your meter. If not, you’ve got a wiring problem somewhere and the GFCI isn’t going to protect you!
Now press and hold down the “Reset” button for 30 seconds while nothing else is plugged into the receptacle (or something that doesn’t require GFCI protection). After this interval has passed, unplug the GFCI and plugin something that you know is grounded (like a lamp or heater). If it doesn’t light up, then there’s still a problem with your wiring.
If the item plugged into the GFCI receptacle does turn on, then congratulations, your GFCI is working properly! Now you can press the “Reset” button again to re-arm it for another test. If you don’t see anything happen when you press “Test,” but do when you press “Reset,” then your GFCI isn’t working. You’ll have to reset it at least once before using it again.
A faulty GFCI receptacle could be either defective equipment bad connections or loose wires due to a short-circuit.

How does a GFCI work?
When you plug in an appliance, the prongs of that appliance connect to one side of the power coming from your house service panel. The other side of that power connects to the ground wire running from your power lines to your electrical devices through their metal casings. When there’s a faulty connection between these two parts, it forces some current to take another route — through the “ground” wire and out into the earth.
GFCIs break this circuit when they detect differences in current going back to its source (your home). This is why you want a GFCI for appliances like clothes dryers and kitchen ranges, which have metal cases around them: If you use the wrong receptacle for these appliances, there’s a good chance of having an electrical fire.
Since they work by detecting small changes in current, GFCI outlets are useful only with “Load” devices that have metal cases–not just appliances, but lights and drills too! This is important to remember if you’re using extension cords or trying to plug more than one device into a single circuit. For example, if three lamps are plugged into an outlet protected by a GFCI receptacle, all three might turn on when you press the “Test” button on the front of your power strip. But if two of them are plugged into non-GFCI outlets (or extension cords), only one will actually get power.
The idea behind GFCIs is actually pretty simple.
They measure the amount of current flowing through the “hot” wire and the neutral wire. If they sense a difference between the two wires, it means that there’s some other path for electricity to flow. It doesn’t have to be another hot wire — any ground connection will do. Since water pipes are connected to sewer lines buried in the ground, this presents quite an attractive route for electric current to take!
When you plug anything into a GFCI receptacle, it immediately detects any difference between its own hot terminal and its neutral one, then breaks the circuit before there’s enough electricity flowing through your body to do damage. The outlet does this by working with your home’s wiring: It actually monitors the current going to each individual device plugged into it and instantly disconnects it when anything goes wrong. So if you plug a fan and a heater into the same outlet, the GFCI will monitor their power supply individually.
There’s another benefit to GFCIs
They keep electricity flowing only one way through long extension cords. If there’s a ground connection somewhere in that cord, then any appliance attached to it will have its metal case grounded directly through the earth. This ensures that all of your appliances are protected by having their cases connected to an external source of electricity
GFCIs are pretty simple devices
They just measure current flow!–but they work really well. The real problem is making sure that you’ve wired them correctly into your home’s electrical system. You see, most GFCIs are designed to “protect” one outlet at a time. They’re usually wired into the hot side of an outlet, so that if something goes wrong with that appliance, it’s not protected by anything.
What you need is some sort of plug-in GFCI tester, which you can use to make sure all of your outlets are working properly before you try using them on any appliances or devices.
GFCIs work really well when they’re installed and used the right way! That’s why it’s important for all homeowners to replace any older circuits in their home (even kitchens and bathrooms) with new GFCI-protected circuits. This ensures that your family will be safe even if you accidentally plug something in to an outlet without realizing its risk.

I’m not a licensed electrician, can I still install a GFCI?
How many do I need? Where should they go?
Believe it or not, there aren’t any hard and fast rules to installing a GFCI. The NEC (National Electric Code) is very specific about what you can and can’t do with electrical wiring, but does NOT specify which types of outlets must be protected by GFCIs.
It may seem like we’re splitting hairs here, but the reality is that anyone who works on their own home’s electrical system should know how to properly protect their family from the dangers of electrical shock. Installing a GFCI outlet takes less than 15 minutes, and it’s well worth the added measure of safety.
The NEC does hold some sway when it comes to GFCIs. The section you need to pay attention to is Section 210-7(b), which states:
“Laundry areas, bathrooms, and outdoor areas shall be protected by a type AC GFCI (a type AC circuit with a GFCI receptacle in series with the equipment grounding conductor) located at the laundry area and bathroom locations and at least one type AC GFCI located at an outdoor outlet where electrical accessories such as rototillers and lawnmowers are likely to be used.”
This basically means that if you’re working in any area where water may come into contact with your (laundry room, bathroom, or outdoor outlets) you should have a GFCI outlet there. The NEC is pretty specific about the type of GFCI required as well. The device itself must have “test” and “reset” buttons on it, rather than just one button for testing/resetting the status of the unit. You can also buy combined “test-only” models that will light up when they’re tripped, but these are not acceptable under the NEC requirements.
They do cost more money to install (about $2 per outlet), but the peace of mind you’ll get knowing your family is safe from electric shock is well worth it.
Remember, these are meant to be installed by homeowners. If you’re not comfortable installing

National Electrical Code Requirements for Bathrooms.
The National Electrical Code (NEC) contains the minimum requirements for safe electrical installations in or on any building or structure.
The NEC applies to all wiring, devices, equipment, and systems that are installed or used within any dwelling unit including one-family dwellings. One-family dwellings are unrestricted as to the number of stories in the building structure. All parts of a one-family dwelling, both inside and outside the walls, ceiling, and underfloor must comply with the code’s provisions.
The code does not apply to detached one-family dwellings that do not have connections to electric supply lines that serve other dwellings on the same premises.
One-Family Dwellings: General NFPA 70 National Electrical Code Requirements.
All 125-volt, single-phase, 15- and 20-ampere receptacle outlets in the areas specified in 210.52(A)(1) through (A)(5) and any 125-volt, single phase, 15-, 20-, or 30-ampere receptacle outlet installed for the connection of laundry equipment in accordance with 400.22 and located within 6 feet ( 1.8 m) of a water closet shall be GFCI protected [210.8(A)].
Exception:
Bathroom receptacles within dwelling units shall not be required to be protected by ground-fault circuit interrupters where supplied through an isolated ground [250.146]. (Bathrooms generally fall within the scope of 210.8(A), which requires GFCI protection for all 125-volt, single-phase, 15- and 20-ampere receptacle outlets installed for “the connection of laundry equipment.” In other words, a bathroom cannot be an isolated ground.)
- Bathroom outlet height: 86cm
- Light shielding fabric: 137g/m²
- Height of hanging bar: 97-185cm (38″ -73″) depending on how it is installed. It can be tightened and loosened conveniently and quickly. The mounting brackets (included) can be adjusted up or down in that way that the light shields itself even if the height is not altered.
NEC bathroom Code
You have to have GFCI outlets in the bathrooms. They are for safety reasons. You need a 20-amp circuit, which is different from the other circuits, or they won’t work.
Does a bathroom GFCI need to be on a dedicated circuit?
All receptacles need to be AFCI and GFCI-protected. This means they should be either on a breaker or an individual receptacle that offers this protection.
There should be light fixtures and switches that are on separate circuits for the bathroom. A separate circuit is required for any tub or other large fixture in the bathroom.

Bathroom GFCI 15 or 20 amp?
A common question we field from homeowners is whether to install a 15 amp or 20 amp GFCI (ground fault circuit interrupter) protected outlet in their bathroom. The answer depends on several factors.
The National Electrical Code requires all 125 volts, single-phase, 15 or 20 amp receptacles located in wet/damp areas to be protected by a Ground Fault Circuit Interrupter (GFCI). While the NEC does not specify which type of receptacle must be protected it has been our experience that most local codes follow the guidance of the NEC and require GFCI protection for bathrooms.
If your local electrical inspector specifies that you must have a GFCI protected receptacle then you may only install one that is marked as a GFCI receptacle. This will prevent confusion in the future when you are troubleshooting a problem in your bathroom.
All 15 amp GFCI receptacles are marked with an orange “Test” button and a red “Reset” button on the face of the receptacle – see photo below right.
Some 20 amp GFCI receptacles have similar markings, but they are usually yellow instead of orange. Either type is acceptable to install if your local electrical inspector specifies one over another or no specific color is stated in the code. All 15A-120V GFCI receptacles manufactured after 1995 by Leviton meet the requirements for use in wet locations per UL Standard 943 and are listed to ANSI/UL STD 1446-2008.
Unless your local electrical inspector specifies otherwise you should install a 20 amp GFCI receptacle – but not so fast! First, there are two types of 20 amp GFCI receptacles: one has four slots and the other has five slots on the faceplate.
The only difference is that the one with four slots does NOT have an equipment grounding slot/screw. Without that equipment grounding wire connection your entire metal box, including all pipes, can become energized if current to ground travels through water in the box – not good!
If you don’t require an equipment grounding wire connection (perhaps because you are at the end of an electrical circuit) then install either type of 20A GFCI receptacle. Otherwise, install a 15A-120V GFCI receptacle.
Your local electrical inspector knows the requirements for your municipality – don’t make an expensive mistake that you or others could pay for in an injury or fatality.
If in doubt always ask before proceeding to avoid potential code violations and possible fines. The choice of whether to install a non-GFCI type receptacle is usually left up to the owner/occupant of the dwelling unit per NEC 210.8(B)(3). Install only equipment listed by one of the Nationally Recognized Testing Laboratories (NRTLs) such as UL, CSA, ETL tested to U.S./Canadian Standards and marked with their label logo for wet locations. If you are ever in doubt about what you can or cannot install, contact your local electrical inspector.
Leviton offers a wide selection of GFCI receptacles recognized for use in wet/damp locations including both 15A and 20A types with four or five slots on the faceplate to meet the requirements of most local codes. Quality wiring devices such as receptacles and switches must be properly installed in order to function properly which adds value to you and your home. Leviton also offers Lighting & Power Outlets, Cord Connectors & Taps, Multi-Outlet Adapters, and other devices that help protect people from shock issues around the home.

I understand that GFI is a ground fault interrupter, but I am not sure what the difference between GFI and GFCI is. What does the “C” stand for in GFCI?
GFI stands for Ground Fault Interruptor while GFCI stands for Ground Fault Circuit Interruptor. A circuit breaker alone cannot be used to protect against electrical shocks since electricity can travel through a faulty appliance cord or receptacle (plug).
A device that breaks (shunts) the current at fault is needed to prevent accidents. So when properly wired electrical outlets are provided with these devices, they provide protection against dangerous shock caused by accidental contact of energized circuits.
The GFCI detects a difference in current between the ‘hot and neutral lines.
Any imbalance of current will cause a GFCI to trip off power to the circuit, thus removing the electricity source from an outlet or device.
GFI vs GFCI – Difference between GFI and GFCI
The difference between these two devices is that while regular electrical outlets have only one line going to it when it’s faulty, electricity can flow into it through line 1, then it crosses over to line 2, which is unexpected. So when you are using them at that time there would be a chance for electric shock due to contact with either hot wire(line1 or 2).
But if there was a device inbuilt in the outlets that would prevent this, then there is no chance of getting an electric shock. The device I am talking about here is GFCI(Ground Fault Circuit Interruptor). This interrupts power to the faulty circuit before a dangerous amount of electricity flows over to you when there is a fault in the system.

Can you put 2 GFCI outlets on the same circuit?
I’m having a hard time finding if it is possible to put two GFCI outlets from the same circuit. I have a split receptacle in my garage that has 2 outlets, one of which is wired straight through and the other is GFCI. It would be nice to access both without going out into the rain to switch them on or off.
Zeb, you can replace your existing outlet with a GFCI outlet but not sure if you can get away with putting multiple outlets on one circuit breaker. Be sure to check local code before installing anything new like this! – brent, electricianCAfromTX
Brent, Thanks for your response.
There isn’t a local code in my area for anything to do with home electrical wiring. The last house I lived in was built in the late 80’s – the early ’90s and there were no codes then that required properties to be brought up to any current code.
I have been looking into this, though, and it seems like you can only add one GFCI outlet to a circuit breaker without having them on separate circuits.
In addition, when you split off from a circuit it becomes its own circuit when the load exceeds 15-amps or when two or more receptacles are installed on the same wall box. The latter is not an issue since this is just a ceiling-mounted light fixture but again thanks for your response!
How many outlets can one GFCI protect?
A GFCI receptacle is designed to protect only the load it controls.
For example, on a 20-amp circuit, one cannot connect another appliance or device to an outlet controlled by the same GFCI receptacle because there isn’t any excess capacity left in the circuit.
This can be solved with either a new dedicated circuit for increased loads or simply by adding an additional GFCI into that branch circuit. While the NEC does not address how many outlets may be protected by an individual GFCI, I believe this rule comes from UL 498A and its revisions.
As stated in section 210-7(c) of NFPA 70 , “Where required by Table 210-7(B)(2), each receptacle shall be individually listed for the maximum number of circuits specified in Table 210-7(B)(2).”

What causes a GFCI to trip repeatedly?
A GFCI receptacle that keeps tripping might have a faulty component or it could be wired incorrectly. Some homeowners try to diagnose the problem on their own by resetting the switch repeatedly, but sometimes this can make things worse.
A licensed electrician should inspect the electrical system and the equipment to determine what’s causing the problem.
Voltage too low or too high?
Many people assume that low voltage causes a GFCI to trip repeatedly, when in fact this is rarely true. If you measure 120 volts at a grounded outlet, this is enough electricity for normal appliance operation such as lights and appliances (120-volts x 0.083 amps = 9.72 amps).
But when you add up all of the electricity being used by multiple appliances, you might have more than 15 amps of current running through the circuit. This is when a GFCI should trip to protect people from electrical shock.
A tripping GFCI could also be caused by high voltage because this may indicate that there’s something wrong with an appliance or its wiring which could pose a hazard. If the voltage is too high, it overpowers the sensor in the GFCI and makes it think that there’s dangerous leakage to the ground when in fact there isn’t any.
A licensed electrician will test for correct voltage readings on all outlets before completing an electrical project.
Isolation switch?
Sometimes homeowners confuse their isolation switches with GFCI receptacles. An isolation switch does not protect people from electrical shock.
It’s used to turn off power at a specific circuit in the home so that an electrician can work on wiring without causing a power outage for everyone else who lives in the home. Although GFCIs and isolation switches may look similar, they’re very different devices with separate purposes.
Outlet overloaded?
An overloaded outlet is another common cause of a tripping GFCI. Some plug-in air fresheners have been known to trip these receptacles because they use too much electricity or put out too much heat.
If you’ve been using an air freshener, try removing it to see if your problem clears up. Larger appliances such as ovens may also overload a circuit and cause a GFCI to trip repeatedly.
Electrical wiring problems?
When the GFCI senses current leakage, it trips within 1/40th of a second—50 times faster than most people can blink an eye! A common reason for a tripping GFCI is that the ground wire has become loose or disconnected somewhere along the circuit.
If you’re not sure where it’s located, call in a licensed electrician who knows how to find it. A faulty appliance cord may also cause a GFCI receptacle to trip repeatedly because this can indicate an electrical short as well as overloading on the circuit.
A licensed electrician will ensure that all connections are secure before completing any work.
Incorrectly wired GFCI?
On some circuits, the wiring order is reversed at the outlet so that hot, neutral, and ground are switched around. This is another fairly common reason why a GFCI trips repeatedly.
Not only can this cause a shortage or current leakage, but it can also indicate that an appliance cord isn’t wired correctly which could pose a hazard for everyone who lives in the home.
If you’re not sure how to tell whether your household wiring has been installed incorrectly, hire a licensed electrician to inspect your entire electrical system before using any outlets or plugging in appliances.

Can I replace a GFCI with a regular outlet??
A GFCI outlet is required for bathroom, laundry, and kitchen countertop receptacles in many regions of the US. These include areas that are wet (bathrooms) or present a wet environment (laundry). The NEC also requires some outdoor receptacles to be protected by a GFCI device. However, there is nothing prohibiting you from replacing an existing regular receptacle with one or more GFCIs.
This isn’t typical practice but it’s not prohibited either. If your question pertains to replacing one of these types of receptacles with another type such as an ordinary duplex receptacle then this would violate Article 406 which prohibits removing the ground prong on grounding-type receptacles unless the equipment has been made fully compliant with the most recent revision of the Code or it is necessary to use that receptacle for an exempted appliance.

Should a refrigerator be plugged into a GFCI outlet?
This is a question we have been asked several times by our customers. The answer is no! In this article, I will explain why refrigerators should not be plugged into GFCI outlets, and what to do if you already have a refrigerator plugged into a GFCI outlet.
If allowed to cool from room temperature down to 38 degrees Fahrenheit, most household refrigerators will consume about 30 amps of electricity.
Therefore it’s important for the circuit they are on to be protected by at least that much amperage. If an un-grounded outlet has 20 amps or less of available protective current (amperage), then the refrigerator must be plugged into its own individual dedicated grounded circuit.
These circuits can come in many different forms, including the GFCI type. But in no situation should a refrigerator be plugged into a GFCI circuit that is shared with other appliances or lighting.
What happens when an appliance pulls more current than the branch circuit it is on can safely handle?
This causes either blowing fuses in older houses, tripping circuit breakers in newer homes, or in some cases overheating of wiring insulation. Fires have even been started by overloaded circuits. When this occurs, it’s usually not just limited to one appliance being affected either.
It’s not uncommon for several outlets on the same circuit to go bad at the same time when an overload occurs.
What are examples of appliances that are likely to cause this sort of problem? Space heaters, toaster ovens, microwaves, electric blankets, large screen TVs or computer monitors when in use, and refrigerators are good examples.
In the case of a refrigerator’s electrical wiring undergoing an overload condition, it can cause a “bottleneck” effect.
This means that the available amperage must go through a narrow part of the refrigerator’s wiring because there is not enough electrical space on that branch circuit.
This causes the insulation on this overloaded portion of wiring to overheat and begin melting away. In some cases, wires touching together will cause a short circuit leading to sparks and fire behind your refrigerator!
Most homes have more than one outlet within reach from where someone would be standing while using a refrigerator so there is no reason why the refrigerator needs to be plugged into a GFCI outlet.
If you already have your refrigerator plugged into a GFCI, what should you do? The best option is to unplug the refrigerator and connect it to another nearby outlet that is not shared with any other appliances or lighting.

Should a washing machine be on a GFCI?
The GFCI protects people against electrocution meaning that appliances like washing machines can absolutely be plugged into them without compromising safety because if somebody accidentally gets electrocuted, the GFCI will immediately turn off the power supply.
Although they are not commonly used, there are also GFCIs in bathroom outlets; they prevent shocks when you touch any metal parts of the appliance, like the water lines.
The short answer is no.
A washing machine should never be plugged into a GFI circuit as it can trip even if its electrical system works perfectly fine (such as running non-heavily loaded cycles). Besides protecting people against electrocution, GFIs’ main purpose is to protect an electric appliance against damage due to excess current flow through its conductors.
If a washing machine were to be plugged into a GFI outlet and start a heavy load cycle – which it regularly does in order to agitate the laundry – it would trip the GFI. This is because a heavy load cycle in a washing machine could be anywhere from 60-100 amps, whereas a GFI’s rating is only 32 amps.
The safest option would be to plug the washer directly into the wall using an outlet that has no built-in protection against surges or excess current flow. This way, if something goes wrong with either the appliance or electric system, the risk of damage will still be minimized due to the lack of anything else attached to this circuit.
Conclusion
The National Electrical Code requires that all bathrooms have a GFCI breaker installed. If you are unsure if your bathroom has one, call an electrician to install it or visit the local hardware store for more information about this important safety requirement.
