Why does my GFCI trip randomly?


All of the gfci outlets in the house are daisy chained and they all have the same problem. They will trip randomly more than one time a day, actually it has gotten worse recently and it is several times a day for all gfci circuits. There is not one set of circumstance that cause them to trip. Plugging something in will cause it to trip. Other times nothing is plugged into any of the plugs on the circuit and I hear the pop when it trips. Could they have used the wrong amperage 15 instead of 20? I haven’t tested this yet, but it seems like they don’t trip when something is plugged in and being used. One stand alone gfci for the wate3r softener doesn’t trip.

When I see "random tripping" I think "nuisance tripping". The easiest way to fix this is to remove the daisy chain receptacles off of the feed through GFCI and replace each one with a individual GFCI receptacle. Don't forget you still have a problem but now you can isolate it to one particular point and that...

Most likely, your outdoor GFCI outlet is tripping due to one of these 3 problems:

There’s a ground fault somewhere in the circuit. Moisture invaded the receptacle box. The GFCI outlet is faulty.

So, how do you know which one is your problem? Don’t worry. We’ll show you how to determine what’s tripping your outdoor GFCI outlet and what you can do to fix it.

Live in the Phoenix area and need help from an electrician right away? Just reach out to us now. We always respond quickly.

If the outlet resets but trips again after appliances are plugged in...

...then you most likely have a ground fault somewhere along the circuit or you have overloaded the circuit. A ground fault means that some amount of electricity flowing through the outlet circuit has found an alternate route and is “leaking” or escaping its proper path.

And a GFCI is designed to trip in less than 1/10 of a second when it detects even tiny amounts of leaking current.

Hi all,

I have been having a peculiar issue with one of the GFCI outlets i have in my house. this one is located in the upstairs hallway bathroom and is located right next to the sink. From seeing it trip, I know that the outlets it affects are the ones outside at the front of the house, and the one outlet that is in the basement also towards the front of the house. There have been 5 times it has tripped in the past 2 months:

1) Right after my wife vacuumed, she had it plugged into this GFCI outlet for some reason, and after she unplugged it when she was done, it tripped
2, 3, 4) All happened within 4 hours on the same day, there was a windy rainstorm we had and i noticed the Christmas lights went out and lo and behold the outlet had tripped each time (nothing was plugged into the outlet)
5) I was shaving and have an old electric razor that needs to be plugged in, after i was done I unplugged it from the GFCI outlet, and it tripped.

There have been other...

Random squealing also may indicate loneliness and/or boredom in a dog. If a pooch's favorite human member of the household just left for the day, she may squeal and whine as a means to summon said person back to her. A confused dog may be worried that her companion isn't going to return, and the squealing may be a way to "fix" the nerve-racking situation. Or, the pup may have loads of pent up energy with no-one or nothing to help them release it. Your bored doggie will probably resort to squealing and whining as an invitation to play. In the same vein, your pup may also be feeling a bit neglected by those around her and use sqeealing as an attention-getting tactic. Say, your entire household has gone through a hectic week and no one has had as much time as usual to play or snuggle with Fluffy. Her squealing may be her endearing canine way of saying, "Look at me, guys! I exist, remember? Give me attention!" In other cases, your doggie may just be pleading for more chicken treats,...

I have a 2003 Flagstaff 23 fbs trailer

All electrical appliances are turned off.

Plug into house electrical outlet and trips house GFCI. Works fine when plugged into campground outlet. I read somewhere that the problem is trailer electrical ground.

Where is the ground? On the tongue, electrical box? Camperland want mucho dollars just to diagnose problem.

ANSWER: Greetings thanks for submitting your question on our Ask An RV Question Page.

You are correct in stating that a bad ground or even reversed polarity in your travel trailer could be tripping the

GFCI Receptacle

. GFCI Receptacles look like normal 15/20 amp plugs except that they have a built in circuit breaker. The GFCI plugs are very sensitive to bad grounds and reverse polarity in electrical systems. They will blow when a normal circuit breaker will not.

First I normally do not recommend that a do-it-yourselfer mess...

Thanks for the report, most likely this is not a security concern but it's good to be vigilant and if you're at all concerned, you can update your master password in the LastPass Vault > Account Settings, as well as turn on two-factor authentication if you don't already have it enabled. Our default security settings should also keep you protected from this type of attack but changing your master password doesn't hurt.

I also recommend trying these troubleshooting steps from our FAQ:

My girlfriend asked me this question this morning and since I explained it to her, I though why not write an article and explain to everyone of you about why does USA/UK use 110/120V and others use 220/240V.

United States distribution system actually provides a 240 volt residential service in the form of two 120 volt conductors and a neutral conductor. You can see this if you look inside your breaker panel.
When a load is applied from either 120 volt conductor to the neutral (as is the case for typical receptacles, lights, and so forth) it is using 120 volts.
However, when a load is applied from one 120 volt conductor to the other, without using the neutral, the voltage being used is the sum of both 120 volt conductors (240 volts). This is the case for many water heaters, air conditioners, electric furnaces, clothes dryers, and so forth.

So equipment that is connected to strictly 240 volts is connected with only a two wire cable plus a safety ground...

Physicist: Ground.

You can put a paperclip practically anywhere. All the same, don't try it.

The zero volt, large-slit wire is called the “return” or “neutral” line. If it seems strange that the power company would supply you with a wire that has no voltage, keep in mind that what you really need is a voltage difference. That’s why everything that uses electricity has at least two wires connecting it to its power supply.

Green=ground, Black=120v, White=neutral. Notice that you can easily remove the green lines on the right without actually affecting anything.

The difference between the neutral line and the ground line is that the neutral line carries current (all the current that enters through the 120 volt line has to go back out), while the ground line is literally connected to the ground (usually through your plumbing) and carries no current. The ground and neutral lines are spliced together at the fuse box (and generally again out by the local...
