GFCIs and False Tripping
At SESCOS, we know that a small electrical problem can become a big headache if it isn’t fixed correctly, and in this post, we’ll take a look at a common electrical problem to discover why your GFCI keeps tripping and what you can do about it.
What is it?
The GFCI (ground fault circuit interrupter) is there to protect you. When it senses something blocking the electrical current or a leak in the current, it shuts off the electricity. This is a safety feature. Because the GFCI can detect the tiniest leaks, it shuts off the power to prevent you from getting a nasty shock when you plug something into an outlet.
But sometimes, it trips for no reason, in what electricians call “false tripping” or “phantom tripping.” Why does this happen?
1. You’re Wearing it Out
- The wiring is old and wearing out.
- You’re overloading the current.
- Multiple devices on the same GFCI are causing it to trip.
The solution? Have a SESCOS electrician replace the GFCI, outlet, and wiring, and install new ones if necessary.
2. It’s Too Sensitive
A sensitive person is one thing, but an overly sensitive GFCI can become a phantom tripper. GFCIs are designed to detect tiny fluctuations in current. Some motors naturally change their current levels and the change might cause the GFCI to overreact.
The GFCI might also be sensitive to moisture, and might false trip when it rains or in high-humidity areas.
The solution? A SESCOS electrician can recommend and install a different type of GFCI better suited to that particular appliance or motor. If the GFCI is for an outside switch, make sure it has wiring suitable for outside use and a moisture cover.
3. An Electrical Malfunction
If everything that you plug into the GFCI causes it to trip, you have an electrical malfunction and definitely, need to call an electrician. A SESCOS technician will test the electrical supply and determine if there is a ground fault. Avoid plugging anything in until you call for expert advice.
4. Appliance Overload
GFCIs that are connected to appliances may start to get overloaded over time. As the appliance ages and has to work harder, the GFCI might start picking up excess current and tripping more often.
This is especially true of GFCIs that have to contend with many appliances in the same room, for instance, the kitchen, bathroom or garage.
The solution? Replace older, worn-out appliances and have a SESCOS electrician install new circuit breakers in those areas.
5. Get Audible Alerts
We have added a new post about Audible Alert GFCI outlets – read more about the numerous benefits of upgrading your ground fault circuit interrupter outlets. For those in the Northern Virginia region – feel free to contact us to schedule a comprehensive electrical assessment and upgrade meeting.
Don’t Trip
There are several reasons why a GFCI might keep tripping. In most cases, it’s not an electrical emergency but it is something that could keep creeping up on you until it’s a big problem. Avoid that by calling your local electricians at SESCOS today. We’ll stop the tripping and get you switched back on in no time.
