Ground Fault Circuit Interrupter(GFCI). Sometimes known as a GFI, or a residual-current device (RCD or RCCB). Can refer to receptacles as well as circuit breakers. They detect a leak in current, or an imbalance between the current on the hot and neutral wires. This is used to prevent electrical shock. Use with the [electrical] tag

Why would the neutral wire in my bathroom's outlet box have voltage?
As @brhans noted in a comment to the other answer, your problem is very likely an open neutral on this circuit.
You have another load on the circuit, past the open, which is turned on. The voltage yo …

Can I connect only two wires to GFCI receptacle?
It is perfectly to code to replace a two-prong outlet (without an available ground) with a GFCI.
Never, ever, make a bootleg ground by connect the neutral to the ground pin. …

Can I install a double pole GFCI breaker on a 220V circuit with no neutral wire (10/2 romex)?
Yes, that is exactly what you do. Even though there is no neutral connected to the breaker, you still must connect the pigtail to the neutral bus.
Observe that if you connected this to a MWBC, with tw …

How to wire gfci-switch-gfci
Don’t forget to label that outlet “GFCI protected”. … Edit: as Harper noted in his answer, if you really want the GFCI Outside (so you can reset it there, for example), don’t put it downstream of the inside GFCI. …

Can a neutral be shared beween the line and load side of a GFCI if it's on the same circuit?
A GFCI functions by comparing the current flowing through its hot and neutral LINE terminals. … For a single-phase GFCI to function correctly on the LOAD side, you must connect only one matching set of hot and neutral. Any other connection will prevent the GFCI from functioning. …

New GFCI trips when load wires installed
If the downstream neutral is interconnected to the neutral from another circuit, the GFCI will probably trip. … This is a situation which is difficult to detect without a GFCI. It is also dangerous as a neutral wire could be overloaded and cause a fire. …

Will GFCI outlet protect downstream outlets with ground connected to neutral?
It is legal and advised to use a GFCI to install 3-prong outlets on an ungrounded circuit. This also applies to standard outlets downstream of a GFCI. … The outlets must be labeled "GFCI protected, no ground" (labels should have been provided along with the GFCI).
You should remove all of the "bootleg" grounds. …

Find a neutral/ground bond
Probably not a neutral-ground bond but a neutral-neutral bond where one neutral is post-GFCI and the other is not (or is post a different GFCI). … If you have a separate circuit that does not originate with the GFCI, if must be isolated from the post GFCI circuit. …

GFCI Breaker - Good or Bad?
The tester tries to trip the GFCI by connecting hot to ground through a resistor. In this case, because the resistor connects to neutral instead of ground, the GFCI cannot detect it. … If there is no actual ground in the switch box, you should disconnect the ground pin and label the outlet “protected by GFCI”. …

You cannot combine neutrals from two GFCI breakers; it just won't work. … I have no information on modifying your spa, but if you cannot change it, you'll need a different panel and two duplex GFCI breakers. …

GFCI plug tripping from a refrigerator that is plugged in last on the line
I’m not going to address the issue of if a GFCI is required but instead directly address the asked question.
On a GFCI outlet, the are two sets of hot/neutral connections, “line” and “load”. … This will remove the GFCI protection from all of the downstream outlets. …

Half Hot Outlet Tripping when Light is connected
In your case, current from the switched circuit is returning through the GFCI. Since this current did not originate from the GFCI, it trips. … The half-hot outlet cannot have GFCI protection in this case.
The other option is to use a GFCI breaker to feed everything and restore the GFCI outlet to a normal outlet. …

Is it ok to replace all 2-prong receptacles with GFCI ones without identifying head of circuit?
Now try another outlet, if it turns out that a new GFCI outlet is downstream, either make that an isolated GFCI or go back and replace the downstream GFCI with a normal 3-prong (labeled). … Don't forget to label all GFCI outlets "no ground". …

Split outlet with GFCI breaker?
The issue with GFCI occurs when the neutral from two GFCI breakers are connected together. … This is why a multi-wire branch circuit (MWBC) fed from GFCI requires a 240 volt (double) GFCI breaker, not two 120 volt GFCI breakers, even handle-tied. …
