GFCI outlet (Grand Fault Circuit) is an essential item in homes, especially in places where electricity is close to water such as kitchens, bathrooms, and outdoor spaces. This device protects you from any electrical problem by immediately cutting of electricity once they detected a problem. Patented in 1965, it is commonly found in homes built in 1971 or after.
How does it work?
“Ground fault” is when electricity is free-flowing or is not taking its intended path – in its’ circuit. Whenever current flows in the wrong path, GFCI outlets can detect this problem and is able to shut everything down. The device measures electricity flowing in a circuit and makes sure that the amount current entering and leaving the circuit is the same. If not, it interrupts and shuts off the power.
What if my GFCI trips?
The first thing to do is to assess if your breaker tripped because of just a slight fluctuation or is an actual ground fault.
- Occasional Trip – sometimes GFCI can be a bit sensitive that even humidity can trigger it. If it’s happening occasionally, you’ve checked that there’s no water near outlets and no damaged appliances, you can just reset it with the reset button. For these cases, it usually resets after a single push.
- Actual ground faults – if you’re experiencing persistent trips and observed water near outlets, faulty appliances, or damaged wiring, it may require some troubleshooting. First thing to do is to unplug all devices connected to the circuit and find the source. If you’re unsure what to do, call your local electrician.
There’s also a chance that your GFCI may be damaged and needs to be replaced. Since they’re highly sensitive, the often don’t last that long. They’re especially sensitive to voltage spikes and lightning strikes. You can opt for a replacement or an upgrade with the help of your electrician if you see fit.
Where should they be installed?
The general rule of thumb is to have A GFCI protection in any place that involves water and electricity. That would be the kitchen (including your refrigerator), laundry room, bathrooms, basements, your garage, and every exterior outlet you may have. But if you’d like a longer and more intensive list the National Electric Code (NEC) has a list ow what must be protected in a residence.
Maintenance
To keep your family safe, we recommend testing your GFCI monthly. Start by pushing the “test” button in the device, which simulates a ground fault, and the circuit should immediately trip. Then, push the “reset” button to restore the power to the outlet. Do this test monthly to make sure your GFCI is working properly.
Not sure where to start with GFCIs? Do an assessment of your home and check if you’re protected where you should be. If you’re missing a few places, then it’s the start of adding the extra layer of protection in your home. Call your trusted local electrician to help you plan out the upgrade.
