Self-test GFCI
Residual-current device
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device to quickly disconnect current to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock.
How often should you test a GFCI?
- Press the center "Test" button, then push in the "Reset" button, if applicable.
- Dry the GFI outlet with a standard hair dryer if the outlet has tripped due to exposure to water or moisture.
- Check the main breaker or fuse for the circuit that the GFI outlet is connected to.
How to test and troubleshoot GFCIs?
- First, make sure that the power to the circuit is off. ...
- Remove the existing outlet, noting the “hot” wire (usually black) and the “neutral” wire (usually white). ...
- If there are ongoing wires which continue to the next outlet on the circuit, connect them to the terminals marked LOAD, again black to black and white to white. ...
What is GFCI and how it works?
GFCI stands for ground-fault circuit interrupter and is part of an electric outlet. It is a device that stops the electricity when a imbalance happens between hot and neutral electric lines. It does this by comparing the electricity going to and returning from what is plugged in. It is important to understand how GFCI’s work, where they come ...
What is the function of GFCI?
- Natural degradation through age
- Humidity or heat
- Extended mechanical stress
- Extended voltage stress
Are all GFCI self test?
After June 29th 2015, it is mandatory that every GFCI made feature a self-test and a reverse line-load misfire function. GFCIs that are currently bearing the UL Certification Mark can no longer be produced after June 28, 2015.
What is Self Test outlet?
A self-test GFCI receptacle is a receptacle that regularly tests the ground fault circuit interrupter function by itself, and then cuts off the power to that receptacle when the ground fault circuit interrupter function fails.
Do GFCI outlets need to be tested?
Electrical safety experts and device manufacturers recommend testing GFCI outlets once a month. This may seem unnecessarily frequent, but the safety function of GFCIs can fail anytime and without notice, so there's often no indication of a problem.
What are the 3 types of GFCI?
Three types of GFCIs are commonly used in homes – the GFCI outlet, the GFI circuit breaker and the portable GFCI. All of these GFCIs perform the same function but each has different applications and limitations.
Why does my GFCI keep tripping?
If the GFCI's internal current transformer senses more than a 4-5 milliamp loss, it instantly shuts down the outlet and any outlets it feeds to prevent accidental electrocution. Most often, when a GFCI “trips” it is the result of a faulty appliance plugged into the outlet or an outlet down circuit.
Why does GFCI trip when power goes out?
Circuit overload occurs when more amperage flows through an electric wire or circuit than it can handle. This may happen if you connect malfunctioning or defective appliances. Loose, corroded wires or connections may also be to blame. Once the GFCI outlet senses an overload, it trips or "breaks" the circuit.

How can you tell if a GFCI is bad?
Push Reset Button 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. Pro tip: If the "reset" button trips again every time you press it, there may be a dangerous current leak somewhere on the circuit.
What are the steps in testing GFCI?
How to Test your GFCI OutletPlug a lamp into the GFCI.Turn on the lamp.Push the TEST button on the GFCI. The GFCI should trip, stopping the flow of electricity to the lamp. Note that the RESET button will pop-out.
What is the difference between GFI and GFCI?
Ground fault circuit interrupters (GFCI) and ground fault interrupters (GFI) are the exact same device under slightly different names. Though GFCI is more commonly used than GFI, the terms are interchangeable.
How often should a GFCI be tested?
monthlyGFCIs 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.

Self-Testing GFCI Requirements
Underwriters Laboratories (UL) is a worldwide safety consulting and certification company based out of Illinois. UL has published over 900 standards for safety. Effective June 29, 2015 they made revisions to their UL 943 Standard for Safety for Ground-Fault Circuit Interrupters (GFCIs).
Where did these UL GFCI revisions come from?
The revisions to the UL standard were brought about because the Consumer Product Safety Commission (CPSC) requested auto monitoring requirements on GFCIs. This request was made because it was believed that many individuals did not perform routine tests to ensure that their GFCIs were functioning properly.
What does the UL update mean for you?
The Self-Test function has the ability to automatically, periodically test the status of the GFCI. After the test is complete, the GFCI must visually or audibly indicate its status.
What is CPSC in the safety standard?
A past field study revealed a number of devices that were inoperative, prompting the U.S. Consumer Products Safety Commission (CPSC) to request a change in the safety standard to call for technology that, to the extent practical, would not require users to conduct manual tests.
Can you test a trip solenoid?
It cannot, however, test the trip solenoid driver, the trip solenoid itself or the contacts to see if they are welded. Testing those components can only be done by actually making the GFCI trip. It is not practical to have GFCIs randomly tripping off during self-test cycles.
How often should I test my GFCI?
The Self-Test GFCI Receptacles should still be tested every month. Press the TEST button and the amber light should come on and pressing the RESET button should turn the amber light off. The green indicator light will stay lit throughout this test. This will ensure a functional GFCI receptacle.
What does the green light on a GFCI mean?
There are 2 indicator lights on the face of the GFCI device. The first light will flash green or red to indicate status . The second light will flash amber to indicate a trip or fault. When the device is first wired up or in a tripped condition, the green status indicator light and the amber indicator light should be on.
