Testning GFCI-uttag

Elektrisk säkerhetskontroll

Alla GFCI-utlopp har en känd brist: deras kretsar sliter slutligen, vanligtvis efter ca 10 år, då fungerar de inte längre korrekt. Här är hela historien.

Testning av din GFCI

GFCI-tester

Enbart återställningsknappen kan inte berätta om ett GFCI-uttag före 2006 fortfarande fungerar korrekt - du måste kontrollera den med en speciell tester.

Genom att upptäcka farligt strömflöde och direkt stänga av strömmen, rensar jordfelsbrytare varje år hundratals liv. Men efter 10 år slits det känsliga kretslocket inuti ett GFCI ut. Och vanligtvis säger testknappen på GFCI att du inte har något fel: När du trycker på knappen stängs strömmen av som alltid. Så det enda pålitliga sättet att kontrollera en äldre GFCI är att använda en kretstester som har sin egen GFCI-testknapp (såld hemmahörna och hårdvaruaffärer).

Anslut testaren och tryck på testknappen. Om strömmen slås av fungerar GFCI. Tryck på återställningsknappen för att återställa strömmen. Om strömmen inte går av, byt ut GFCI.

Din nya GFCI kräver aldrig en kretstester. Alla GFCI tillverkas efter mitten av 2006 är utformade för att berätta när de misslyckas. Den stora majoriteten indikerar misslyckande genom att stänga av strömmen permanent. Så som en dag kommer din GFCI (och andra uttag anslutna till den) helt enkelt sluta leverera ström och du måste byta ut den.

FAQ - 💬

❓ 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.

❓ How do you wire a GFCI with 2 wires?

👉 2:523:39How to Wire a GFCI Outlet - 2 wires to GFCIStart of suggested clipEnd of suggested clipConnect your neutral wire to the silver screw the side with the wide slat. Now you can tuck yourMoreConnect your neutral wire to the silver screw the side with the wide slat. Now you can tuck your wires into the box. And tighten down the gfci.

❓ Why is my GFCI alarm going off?

👉 The latest in electrical protection, audible GFCI outlets emit a high-pitched sound to let you know that the circuit has been cut off to an outlet. Once you've been notified of the problem, you can either reset the outlet or plug the appliance into another one.

❓ Where does red wire go on GFI?

👉 The line connection is used for all GFCI outlet installations. The circuit's hot wire (typically colored black or red) connects to the black or brass-colored screw terminal marked LINE. The white neutral wire connects to the silver-colored screw terminal marked LINE.

❓ What's the difference between 15 and 20 amp GFCI?

👉 20-amp circuits are designed for a heavier load of electrical current than 15-amp circuit breakers. For commercial and industrial power distribution, the circuit breakers will have a higher amperage.

❓ Is there a 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.

❓ Are 2 prong outlets legal?

👉 Are Two Prong Outlets Legal? According to the National Electric Code, two-prong outlets are allowed in homes as long as they are properly working. If you choose to replace your two-prong outlet, you do not have to upgrade to a newer model.

❓ Can you sell a house with 2 prong outlets?

👉 Can You Sell a House With Two-Prong Outlets? According to the National Electric Code, you can sell a house with existing two-prong outlets as long as they're working correctly. Even if you choose to replace two-prong outlets, they do not have to be rewired and upgraded.

❓ How do you fix a GFCI outlet that keeps tripping?

👉 3. Overloaded Circuit

  1. Unplug all the appliances connected to the circuit in question.
  2. Reset the circuit on your fuse box.
  3. Wait several minutes.
  4. Plug an appliance back in and turn it on.
  5. Check to see that your circuit has not tripped.
  6. Plug in the next appliance, turn it on, check the breaker, and so on.

❓ What happens if you switch line and load on GFCI?

👉 If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will not reset and will not provide power to either the GFCI receptacle face or any receptacles fed from the GFCI.

❓ What happens if you reverse line and load on GFCI?

👉 If you miswired the GFCI it may not prevent personal injury or death due to a ground fault (electrical shock). If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will not reset and will not provide power to either the GFCI receptacle face or any receptacles fed from the GFCI.

❓ How do you test a GFCI outlet?

👉 How to Test a GFCI Outlet. Look at the face of the GFCI outlet: between the two sets of slots where you plug in cords there are two rectangular buttons, labeled "TEST" and "RESET.". To test your GFCI, simply press the test button with your finger. You will hear a snap sound that trips the outlet and cuts off the power to the two plug connections.

❓ How do I know if my GFCI is working or not?

👉 Plug in the tester and push its test button. If the power goes off, the GFCI is working. Press the reset button to restore power. If the power doesn’t go off, replace the GFCI. Your new GFCI will never require a circuit tester.

❓ How often should GFCI circuit breakers be tested?

👉 GFCI circuit breakers also should be tested monthly. The test is similar to testing GFCI outlets. You simply open the door on your home's service panel (breaker box) and press the test button on the GFCI breaker.

❓ How long does a GFCI last?

👉 But after 10 years or so, the sensitive circuitry inside a GFCI wears out. And usually the test button on the GFCI doesn’t tell you there’s anything wrong: When you press the button, it shuts off the power as always.
