The ground wires are twisted together and then connected to the GFCI ground. The black and white wires may also be twisted together and then using a jumper wire connected to the GFCI. Hard to say without seeing exactly how it is wired.

How do you wire a gfci outlet with fan switch?

Home depot sells RF switches whereby if the fan is connected to the transmitter. It can be controlled by as far as 5 meters i believe In my SPA i have this device for safety. switch here get turn on there


Do all electrical outlets in a garage need to be GFCI?

Yes, but you can feed multiple outlets from one GFCI outlet. Make the first outlet fed in the cicuit a GFCI. Search for GFCI outlet with Google, etc. and I'm sure you will find an explanantion of how. Most GFCI's come with instructions also.


What happens when you plug a GFCI protected extension cord into an outlet that is GFCI protected?

In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)


What would be the correct wiring for 3 sets of wires into a GFCI outlet?

I'm assuming your 3 sets of wires are black or red, or some other color normally associated with the "hot" wire, a white for neutral and a green or bare conductor for ground. If your GFCI protects only itself and no other receptacles, you splice all the wires of the same color together and attach 'pig tails' to your splice to connect to the GFCI. If your GFCI protects other receptacles 'down stream', you connect only the hot and neutral feed from the panel to the line side of the receptacle. Then you splice the others together as described above and connect your pig tails to the load side. "Line" and "load" should be clearly marked on the GFCI. Your ground in this case is still all spliced together with a pigtail for connection to the GFCI. Line is from the panel. Load is to other receptacles. Getting these reversed will prohibit your GFCI from functioning properly.


Will a gfci breaker work when neutrals and grounds are together in main panel or will there have to be a separate ground bar installed and wires separated?

Yes a GFCI will work if the neutrals and ground are to together the main panel. This is considered the line side of feed side of the GFCI. Neutral and ground can not touch down stream from the GFCI or on the load side of the GFCI.

Do you wire a gfci outlet differently?

No, except that you insert the wires into the holes on the back of the outlet. The power in connects to the LINE side of the outlet and power out connects to the LOAD side of the outlet. This is clearly marked on the back of the outlet. This will not only protect the outlet with the GFCI installed but all outlets receiving their power from that GFCI. If you do not want to protect the outlets receiving power from the outlet then connect that outgoing wire to the LINE side also. But know that only the outlet with the GFCI will be protected and all other outlets will not be GFCI protected.


The GFCI outlet's reset button does not pop out when the test button is pressed it is already out and when I try to press it in it will not catch although it does have power?

This indicates either you have an active ground fault or the GFCI is bad. To check this out turn off power at breaker and remove GFCI outlet from wall box. Determine if it is powering other non-GFCI outlets. (It will have both input and output wires. If there are output wires remove them and check the outlet again with power and see if it resets. If it does you have a ground fault down the line somewhere. If it still doesn't work you likely have a bad GFCI.


When would it be a better idea in a residence to install a GFCI breaker instead of an GFCI outlet?

GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.

Do you need a gfci outlet if you have a gfci breaker?

Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.


Why does a newly installed GFCI outlet show open ground on the tester?

Ground wire is loose or disconnected somewhere in that circuit.

Can you use a GFCI plug into a GFCI outlet?

Yes you can. Lots of blow dryers have GFCI protection built in.

How do you wire an outdoor timer into a GFCI outlet?

I assume you are hard wiring it and not plugging it in. The power coming into the GFCI outlet connects to the line side of the GFCI outlet. If you want the outdoor timer protected by the GFCI then connect the wire going to the timer to the load side of the outlet. If you do not want the timer protected then connect it to the line side. On the back of the GFCI if you look closely you will see Line & Load marked on the back.
