The ground-fault circuit interrupter, or GFCI, is a fast-acting circuit breaker designed to shut off electric power in the event of a ground-fault within as little as 1/40 of a second.However, it protects against the most common form of electrical shock hazard, the ground-fault.
Do you need GFCI protection?
Where GFCIs Are Required. GFCI protection is required for 125-volt to 250-volt receptacles supplied by single-phase branch circuits rated 150 volts or less to the ground. GFCI receptacles are required in bathrooms, garages, crawl spaces, basements, laundry rooms and areas where a water source is present.
What is a GFCI and why is it important?
Ground-fault circuit interrupters (GFCIs) are used for protection from an electrical ground fault. They will also protect against fires and overheating. A GFCI is a fast-acting circuit breaker designed to turn off electric power in the event of a ground fault.
How does a GFCI outlet work?
GFCI outlets and breakers have a sensor that detects electrical imbalances as low as 4 to 5 milliamps across the hot and neutral wires. When an imbalance occurs, the sensor instantly breaks the circuit rendering the circuit dead. Power can be restored by resetting the tripped outlet or breaker.
Do all bathroom outlets need to be GFCI?
Bathrooms All bathroom receptacles should have GFCI outlets installed.Any outlets within six feet of this sink (and the dedicated washing machine outlet) should be equipped with GFCI outlets. Outside All outlets installed outside of your home should be GFCI outlets.
Does a dishwasher need GFCI protection?
GFCI protection is not required for receptacles serving appliances like dishwashers, or convenience receptacles that do not supply countertop surfaces. Receptacles installed within 6 ft of the outside edge of a wet bar sink must also be GFCI-protected [210.8(A)(7)].
Does a freezer need a GFCI?
A. That “protector outlet” you’re referring to is a GFCI, or “Ground Fault Circuit Interrupter” receptacle, and GFCI’s are required by building code in garages, kitchens, bathrooms, and on the exterior of new homes.So freezers and refrigerators should never be plugged into GFCI’s.
What does a GFCI outlet look like?
A GFCI receptacle is easily recognizable. Simply look for the test and reset button on the face of the outlet. When installed, any electrical device that is plugged in will be protected in the case of a ground fault. This also includes any electrical outlets that are connected on the same line.
What are the benefits of using GFCI in your home?
A GFCI outlet helps in preventing shocks and electrocutions as it has a built-in sensor that monitors the inflow and outflow of the electricity from any appliance. If a live wire inside the appliance comes in contact with the metallic surface of the appliance, you will get a shock when you touch it.
What must you do to ensure that the GFCI devices you are going to install are in good condition?
GFCIs should be tested monthly to ensure they are in working condition. Whether you have a receptacle or circuit breaker GFCI, pushing the TEST button should turn off the power to the circuit. For the receptacle-type GFCI, pushing the TEST button should cause the RESET button to pop up.
How do I know if my GFCI is bad?
Push Reset Button
- Look for GFCIs in bathrooms, kitchens, basements, garages and on the home’s exterior.
- If the GFCI won’t reset or the button doesn’t pop out when you press the “test” button, there may be no power to the GFCI or you may have a bad GFCI.
What happens when GFCI goes bad?
How to Tell If a GFCI Is Bad. When a GFCI trips, it won’t supply power, so your hair dryer or power saw won’t work, and if a tripped GFCI is at the beginning of a circuit, it will cut power to the entire circuit, so other outlets and lights on the circuit won’t work either.
What’s the difference between GFI and GFCI?
There is actually no difference at all.
A common conversation when discussing receptacles may be referring to a ground fault circuit interrupter (GFCI) as simply a ground fault interrupter (GFI). They are generally the exact same thing.
Why do bathrooms need GFCI?
Electricity and water don’t mix
Water and electricity are a recipe for disaster. Codes mandate strict guidelines for GFCI outlets throughout the United States. According to the National Electric Code (NEC), it requires a minimum of one GFCI-protected outlet per bathroom.
Does a dryer need a GFCI?

What is code for electrical outlets in a bathroom?

Do kitchens need GFCI?
Kitchens: All receptacles serving countertop areas and any receptacle within 6 feet of a sink must have GFCI protection.Laundry, utility, and wet bar sinks: Where receptacles are placed within 6 feet of the outside edge of the sink, they require GFCI protection.
Do garbage disposals need GFCI?
The National Electrical Code (NEC) does not require a garbage disposal to have GFCI protection. GFCI protection for this appliance is optional.Garbage disposals should be either hardwired or connected to an outlet through a grounded electrical outlet.
What appliances require GFCI protection?
Vending machines, cord-and-plug-connected spray washers, drinking fountains, auto vacuum and tire inflation machines installed for the public require GFCI protection.
What happens if you put a freezer in a garage?
Changes in temperature in an unheated garage can be a problem.If your freezer’s compressor has to work overtime to maintain its interior temperature when it’s very hot in your garage, it costs you more to run the appliance. If it’s too cold and the compressor shuts off, your food could thaw.
Can I install a non GFCI outlet in my garage?
Our electrician told us that since 2008 you cannot have a non-GFCI outlet in your garage.Non-GFCI outlets are a safety hazard when they are installed in garages, so it is definitely better for them not to allow them in garages, but it does cause quite a bit of inconvenience when it comes to plugging in a refrigerator!
